INTRODUCTION The CS8 console has been designed to provide the consultant, contractor, installer and user with a cost effective system which will perform to accepted professional standards, be simple for the untrained user to operate, and be tolerant of wiring and installation problems. There can be no excuse for a system which is over sensitive to the wiring and installation conventions used, and hums at every opportunity. High quality balanced inputs and outputs are only part of the story. Equally important is the way in which the console grounding system works, because it is through the console ground that all the noisy ground currents from the cable screens will flow. Any part of the audio signal path which shares the cable screen to console ground path within the console will effectively have the cable screen noise added to that signal path. The current flowing in cable shields in typical installations has be shown to be substantial (in the order of 100mA and above) and is caused by the difference in potential between the ground connection at each end of the cable screens. Of comparable importance to any system performance is the power supply. Internal linear power supplies may be less expensive, but are usually responsible for inducing noise into the audio and generating substantial amounts of heat, making it uncomfortable for the operator. Internal switch mode supplies may be cool running, but are usually even more of a problem with regard to noise. Another often overlooked point with internal power supplies is how to provide auto-switchover between 2 supplies without extensive modification thereby nullifying the warranty. Internal supplies are also a potential problem from a maintenance point of view. Most service technicians can easily fault find and repair a linear supply with commonly found components, but a switch mode supply does not make use of common off the shelf components. Although more expensive, a separate and generously rated linear power supply is used with the CS8 keeping heat and noise away from the console. Rack mounting ears are available for permanent installations, and the supply is UL and CSA approved. At this point it is useful to look at some of the features of the CS8. PAN AND ROUTING The pan pot can be switched between stereo panning mode, and left/centre/right panning mode. Left-centre-right panning to the master outputs provides much improved spatial positioning. The technique has been used for many years in the film industry where its benefits are well known. 4
In music systems the centre channel generates a more solid centre image, especially for the “star” of the show, and helps to maintain a stereo image across a wider sound stage. In mixed media productions and in church applications the use of a speech optimised centre cluster can improve intelligibility without compromising the music system performance. If only a stereo system is being run, and the pan pot is switched to stereo mode, then the centre output is individually assignable from each input or the from a sum of the left/right mix to provide a separate mono output for broadcast/film feeds etc. Another unique feature for a mixer in this class is individual sub group routing instead of the inconvenient and inflexible paired routing which always requires the use of the pan pot to route a channel to a single sub group. There is always a crosstalk performance compromise involved and it is done solely for economic rather than for operational reasons, as it halves the number of routing switches and removes the need for a pan in/out switch. The CS8 allows routing to the sub groups either individually or in pairs via the pan pot. EQUALISATION The CS8 input module has a 4 band equaliser with high and low frequency boost/cut controls and two swept frequency middle sections. There is more than two octaves of overlap between the frequency ranges of the mid equalisers while the frequency span extends to from 70Hz to 10kHz. AUXILIARIES The CS8 has 8 full time auxiliary send controls allowing easy session setup. These are normally post fade but can be switched pre fade. Normally the pre fade signal is pre fade post cut but byusing internal links it can be changed to the pre equaliser signal. Auxiliaries 7 and 8 can be used in stereo where stereo foldback, for example, is required. CHANNEL CUT The channel cut is a silent FET switch which can be remotely controlled through a connector on the rear of each channel by a simple connection to ground. In addition, when the channel cut switch is pressed, another contact is grounded on the Mute Remote connector. This can be used to control a Midi Mute controller, cue lights, or even to control another channel on the mixer by linking the mute out pin of one channel to the mute in pin of any other channel(s). Such an application could be a podium switch which would allow the speaker to override other channels for example.
5
SOLO/PFL MONITORING While it is normal to find PFL/AFL on almost all mixers, the CS8 goes a step further. The input solo is arranged to have priority over the output solo. This means that there is no need to de-select an output solo when selecting one or more input solo controls, and when the input solo is released, the output solo is re-established. A master solo level trim control is located on the master module for level matching, and the level of the solo signal is displayed on the left mix bargraph. An additional solo feature provided is Solo In Place. In this mode, soloing any input channel will cause all other input channels to be cut, thereby allowing only itself to be heard in the mix, correctly panned and at the right level, along with any stereo effect return channels. This is of great benefit during set-up and rehearsal and is much more useful than the standard PFL. A switch on the master module selects Solo In Place mode. SIGNAL LED’s The value of effective metering of signal levels throughout the signal path cannot be overestimated. Signal present and 0dB LED’s on all input channels give confidence to the operator while peak overload LED’s indicate when the channel is being driven close to clipping. However, it is unusual to find a peak overload LED at the very place where it is most needed, at the summing bus mix amplifiers, operating independently of the output meters. If the mix amplifier is overloaded and starts to clip, the only thing that can be done to rectify the situation is to pull down all input faders. On the CS8, there are overload warning LED’s on each of the sub group mix amplifiers as well as on the left, centre and right mix amplifiers. When the output meters are switched to observe the matrix outputs the bus peak leds also monitor the matrix bus. INSERTS Inserts are used to patch in external pieces of equipment such as equalisers, limiters etc. and are provided on all channels, group outputs, mix outputs and auxiliary outputs. To be useful and useable, the inserts should be at a level which is compatible with this external equipment. Sadly, this is often not the case. Some mixers have inserts at odd levels which will preclude their efficient use because of the noise penalty. All inserts on the CS8 are at a consistent level which is at the internal operating level of 0dBu. AUXILIARY INSERTS In most installations, it is quite normal to place an equaliser in the stage monitor sends, but this is normally external to the mixer. This of course means that the only way of listening to the monitor sends (internal to the mixer) is via the solo system. 6
Herein lies a problem. The operator does not hear the effect of the external equalisation. Also, any noise introduced by the external device is constant and not proportional to the setting of the send control. The ideal place to insert an external device is pre the send master control and this is the case in the CS8.

INSTALLATION GUIDE There are a number of points to consider when installing a mixing console. Many of these points will have been addressed before the console is even unpacked but it is worth repeating them again. POSITION The console should be located in a convenient space commensurate with the use to which the console is being put. Ideally a cool area is preferred not in close proximity to power distribution equipment or other potential sources of interference. Provision should be made for some flat surface surrounding the console to prevent people using it as a table top. One of the worst fates that can befall a console is for a cup of coffee to be tipped into it by someone resting it on the control surface! POWER The power supply should be located as far from the console as the connecting cable will allow, a 5 metre power cable is supplied with the console. It should be set for the appropriate line voltage and plugged into the mains outlet using the supplied cable. If the power supply is rack mounted then be sure to leave space above for ventilation - 2U is suggested.

WIRING The console uses four different connector styles:TRS jack sockets, XLR male connectors, XLR female connectors and phono connectors. The cables used should be of as high a quality as possible. Many installation problems can be traced back to poor or faulty cables and connectors. There are two different conventions for the wiring of XLR connectors. The international convention uses pin 2 as the hot pin while the older American convention uses pin 3 as the hot pin. When going from balanced input to balanced output this is of little consequence but when unbalanced signals such as those found on the insert points are used then phase reversal can result. The CS8 and all DDA products are wired PIN 2 HOT.
ATTENTION CABLES This product should only be used with high quality, screened twisted pair audio cables, terminated with metal bodied 3-pin XLR connectors. The cable shield should be connected to Pin 1. Any other cable type or configuration for the audio signals may result in degraded performance due to electromagnetic interference. ELECTRIC FIELDS Should this product be used in an electromagnetic field that is amplitude modulated by an audio frequency signal (20Hz - 20kHz), the signal to noise ratio may be degraded. Degradation of up to 60dB at a frequency corresponding to the modulation signal may be experienced under extreme conditions (3V/m, 90% modulation). No permanent damage or degradation of performance will be caused by these conditions.
13
CIRCUIT DESCRIPTIONS The following gives a brief description of each module as an aide to understanding the signal flow within the console. Many references are made to the circuit diagrams with the reference number for the appropriate diagram being given at the beginning of each module. The master module uses two circuit boards requiring four circuit diagrams.
INPUT MODULE (CD1279) The input module contains eight input channels mounted on a common set of metalwork. The channels are identical and a console is constructed by using 2 or more input modules together with an output module and a master module within a frame. THE INPUT STAGE (CD1279) The same input stage is used for both the microphone and the line input. CON2, an XLR style connector, is used for the microphone input which is wired to the inner contacts of CON3, the line input TRS jack. With nothing inserted into the jack socket the signal connects to the normal contacts and is then fed to an attenuator which is activated by selection of the line input. Resistors R2 and R3 feed phantom power to the microphone input and this is DC blocked from the line input amplifier by C2 and C3. SP1, SP2 and SP6 are filters providing protection from high frequency signals entering the inputs. Additional filtering is carried out by capacitors C37, C38, C39 and C40. CON9 (optional) is wired in parallel with the XLR which allows for wiring the input to a multipole connector mounted on the console frame. Resistors R7, R8 and R9 form an attenuator when the line input is selected, reducing the input signal by 30dB. C45 and C46 again provide DC isolation and there is provision at this point for the insertion of an input balancing transformer. Note that if a transformer is fitted R14 should be changed to 1k. Where a transformer is not fitted two 10R resistors (R10, R11) carry the signal through to the input amplifier. D1, D2, D3 and D4 provide clamping for excessive input voltages and the signal is applied to the bases of transistors Tr5 and Tr7. VR1 is the front panel gain control and this is connected through the MIC/LINE switch such that in the MIC position the gain range is 20 to 70dB while in the LINE position it is -10 to 20dB. Signal is taken from the collectors of Trs 5 and 7 and applied differentially to the input of IC1A. The output from here is fed back to the emitters of the input transistors through 56k resistors with one side being phase inverted by IC1B. The phase reverse 14
switch, SW3, selects either the normal or the phase inverted signal and feeds it to the high pass filter stage. This is a three pole high pass filter operating at 80Hz giving a roll off of 18dB per octave. When not required this can be completely bypassed by SW4. The output of SW4 after buffering by IC8B is known as PRE1 and is the pre equaliser signal. PRE1 is a source for the auxiliary sends which will be referred to later. THE EQUALISER The signal is presented to the equaliser which is a four band design. The high and low frequency sections are built around IC2B with VR7 providing low frequency boost and cut while VR2 provides high frequency boost and cut. The middle frequency sections are built around IC3 and use a Wein bridge as the frequency determining network. VR3 selects the frequency of operation and VR4 determines the amount of boost or cut given to the hi mid signals while VR5 alters the frequency and VR6 the boost or cut for the lo mid signals. The output from the equaliser connects to SW5 the EQ IN/OUT switch where either the pre equaliser sinal or the equalised signal can be selected to be passed to the insert send. CON5, a Tip, Ring and Sleeve jack, is used for the insert point with the Tip being used as the send. SP3 and SP4 are filters preventing noise from entering the console. The insert return signal is buffered by IC7A and is then presented to the channel fader. The output from the fader feeds the channel cut circuit. The pre fader signal feeds the auxiliary cut circuit, the solo bus when a solo is requested and finally the 3 led signal meter which is driven from IC6, a quad comparator. There are SIGNAL PRESENT, 0dB and PEAK indicators which are powered from a current source built around Tr8. The auxiliary cut allows the creation of a PRE FADE POST MUTE signal, which can be defeated if required, in addition to the POST FADE POST MUTE signal. THE MUTE CIRCUIT Tr1 is the CHANNEL MUTE fet which is buffered by IC4A and following this the signal is known as POST. This signal routes to the groups when panning is not used and also feeds the auxiliary sends when selected as POST. The pre fade signal goes through a second AUXILIARY MUTE circuit built around Tr2 to give a PRE FADE POST MUTE signal called PRE2. LK1 is normally installed allowing the PRE FADE signal to be muted when the channel mute is operated. By removing LK1 and installing LK2 the PRE FADE signal will not mute with operation of the channel mute switch.
15
In order to improve the attenuation of the mute circuits a small amount of signal is fed forward to cancel with any residual from the output of the fets. Resistors R140, R141 and R142 perform the feed forward for the channel signal while R99, R100 and R101 are used for the auxiliary cut circuit. The mute circuit can be remotely controlled either through the external remote connector or from the four mute groups provided. A SAFE button allows the mute groups to be disabled on the module. When the local mute button is pressed a ground is placed onto the remote control connector. This can be used to operate external equipment such as a midi sequencer or it could be connected to other channels so that when one channel is muted others will also mute. Led 1 indicates a MUTE whether it is local or remote. In every case a MUTE request grounds the base of Tr6 causing it to switch off and hence its collector to go high. This is applied to the gates of Tr1 and Tr2 causing them to switch off since they are P channel fets. Tr4 will also turn off causing Tr3 to turn off allowing led 1 to indicate the mute condition. THE PAN CIRCUIT The POST signal next goes to the pan circuit. This circuit can be switched between stereo (L/R) and left/centre/right (LCR) modes using SW15. The output of the pan pot can be routed to the mix or the groups. If panning to groups is not selected then the groups receive the POST signal while, with panning selected, they receive the output of the pan pot (PANL and PANR). If LCR panning is selected then assigning to mix (SW13) will send signal to the left centre and right buses. If L/R mode is selected no signal will appear on the centre output except by pressing the MONO button (SW27) when the POST signal will be routed to the centre bus. The groups can only use the left and right pan pot outputs and therefore if LCR panning is selected, panning to groups will not function in the expected manner. The pan pot is built around VR16, a dual pot, and IC5. When in L/R mode only one section of the pot (VR16A) is used and it simply reduces the resistance to ground of the left or right signal depending upon the direction of rotation. This reduces the amplitude of the signal on one side while increasing it on the other to create the panning effect. When LCR mode is selected the input signal is fed to a centre tap on VR16A. Signal can thus only appear on the left or right output of this section of the pan circuit (but not both together) with the amplitude depending again on the rotation of the pan pot. 16
The centre output is derived from the same input signal and VR16B is used to control its amplitude by decreasing the resistance to ground when the pot is rotated away from its central position. IC5B buffers the centre signal. THE AUXILIARY SENDS The auxiliary sends can use the following three signals :PRE1, PRE2 and POST. PRE1 is the pre equaliser signal, PRE2 is the pre fader post mute signal and POST is the post fader post mute signal. All auxiliaries will normally receive the POST signal, however, there are PRE switches associated with the auxiliaries allowing the pre fader signal to be selected. The default condition is that PR2 shall be the pre signal although links allow this to be changed to the PRE1 signal. Only one link of a pair should ever be inserted. Auxiliaries 1, 2, 3 Link 4 PRE1 Link 3 PRE2 Auxiliaries 4, 5, 6 Link 5 PRE1 Link 6 PRE2 Auxiliaries 7, 8 Link 7 PRE1 Link 8 PRE 2 THE SOLO FUNCTION SW22 is the solo or PFL switch. When operated it places DC onto the IPCUEDC bus which is detected by the master module. The audio signal INS_RET is fed onto the IPCUE bus and fed to the monitoring system on the master module. If Solo In Place mode is selected then the module initiating the solo will have its solo switch depressed and the incoming SIP signal will have no effect. If the module did not originate the solo in place the solo switch will not be depressed and the SIP signal will cause the channel to mute. THE DIRECT OUTPUT The direct output is available at CON5, a jack connector. The signal is unbalanced, at a nominal level of 0dBu and by default is the POST signal. SW28 allows the PRE1 signal to be used.
17
Switches 9, 10, 11, 12, 23, 24, 25 and 26 route the signal to the groups. Switch 27 routes signal to the MONO (CENTRE) bus and SW13 routes to the stereo MIX bus. ROUTING AND MUTE GROUPS Switches 18, 19, 20 and 21 select the mute group buses. They are combined through diodes D11 through D14 and then go to the SAFE switch SW17 before combining with the local and remote MUTE signals. GROUNDING All routing to buses is through 10k resistors. All connectors are grounded to the metalwork (chassis) ground. This is connected to 0V by a 100R resistor in parallel with a 10n capacitor. BUSREF is taken from 0V through a 10k resistor. There is provision for an external meter output on CON8 (option).

INPUT MODULE BLOCK DIAGRAM
THE STEREO INPUT MODULE (CD1302/3) THE INPUT STAGE The same input stage is used for both microphone and line inputs. Looking at the left signal path, CON2, an XLR style connector, is used for the microphone input which is wired to the inner contacts of CON3, the line input TRS jack. With nothing inserted into the jack socket the signal connects to the normal contacts and is then fed to an attenuator which is activated by selection of the line input. Resistors R2 and R3 feed phantom power to the microphone input and this is DC blocked from the line input amplifier by C2 and C3. SP1, SP2 and SP3 are filters providing protection from high frequency signals entering the inputs. Additional filtering is carried out by capacitors C37, C38, C39 and C40. Resistors R7, R8 and R9 form an attenuator when the line input is selected, reducing the input signal by 30dB. C45 and C46 again provide DC isolation and there is provision at this point for the insertion of an input balancing transformer. Note that if a transformer is fitted R14 (R214) should be changed to 1k. Where a transformer is not fitted two 10R resistors (R10, R11) carry the signal through to the input amplifier. D1, D2, D3 and D4 provide clamping for excessive input voltages and the signal is applied to the bases of transistors Tr4 and Tr5. VR1A is the front panel gain control and this is connected through the MIC/LINE switch such that in the MIC position the gain range is 20 to 70dB while in the LINE position it is -10 to 20dB. Signal is taken from the collectors of Trs 4 and 5 and applied differentially to the input of IC1A. The output of IC1A is fed back to the emitters of the input transistors through 27k resistors with one side being phase inverted by IC1B. The phase reverse switch SW28 (located in the left signal path only) selects the normal or phase inverted signal and passes it to the high pass filter formed around IC2A. This is a three pole high pass filter operating at 80Hz giving a roll off of 18dB per octave. When not required this can be completely by-passed by SW3. The output of SW3 passes through SW19, the MONO R switch to become PRE-L1 which is the pre equaliser signal (left). It is a source for the auxiliary sends which will be referred to later. SUMMING AMPLIFIER IC11A sums the left and right signals together to create a mono signal which has its polarity restored by IC11B before being presented to switches SW19 and SW20 (the left and right signal cut switches). When Mono R (switch 19) is pressed the left signal is cut and replace by the right signal. Similarly when Mono L (switch 20) is pressed the right signal is cut and replaced by the left signal. If both switches are pressed the output of IC11B (a mono signal) is fed to both left and right signal paths. 21
THE EQUALISER PRE1 L1 is presented to the equaliser which is a four band design. The high and low frequency sections are built around IC9A with VR6 providing low frequency boost and cut while VR2 provides high frequency boost and cut. The lo middle frequency section is built around IC8/IC202A. VR15 selects the frequency of operation and VR14 determines the amount of boost or cut given to a signal. The hi middle frequncy section is built around IC15B and IC16A. VR17 determines the frequency of operation while VR18 determines the amount of boost or cut. The equaliser output feeds the EQ IN/ OUT switch, SW29 allowing the pre or post equaliser signal to be selected. IC7A buffers the equaliser output and feeds it to the fader. The equaliser output is also used to derive the PFL signal and to drive the SIGNAL PRESENT, 0dB and PEAK indicators. THE CUT CIRCUIT The signal path splits at this point to go through two cut circuits. This allows the creation of a PRE FADE POST MUTE signal (which can be defeated if required) in addition to the POST FADE POST MUTE signal. Tr1 is the CHANNEL MUTE fet and the post cut signal is buffered by IC4A. The signal leaving IC4A is the POST FADE signal which is then fed through a pan pot that can be routed to the groups or the L/R mix. The pre fade signal goes through an AUXILIARY MUTE circuit built around Tr2 to give a PRE FADE POST MUTE signal called PRE2. LK1 is normally installed allowing the PRE FADE signal to be muted when the channel mute is operated. By removing LK1 and installing LK2 the PRE FADE signal will be unaffected by operation of the channel mute switch. IC12A is used to combine the left and right post fade signals for sending to the auxiliaries. IC12B is used to combine the left and right pre fade signals for sending to the auxiliaries. As with the input module a small amount of signal is fed forward to cancel any residual from the fets to improve the mute attenuation. THE BALANCE CIRCUIT The post fade signal next goes to the balance circuit. The output of the balance pot can be routed to the mix or the groups. The groups normally receive the mono post fade signal but with the PAN switch depressed they will receive the outputs of the balance pot built around VR16. By default the balance control works as a pan pot with full attenuation of the unwanted side. A more limited range of adjustment can be obtained by changing the circuit as follows :-
22
Move R140 to R141 and R341 to R340 leaving the positions for R140 and R341 blank. Make R142 and R342 both 10k (they are 0R links). This will then give a balance range of +3/-6dB.
PEAK AND SIGNAL PRESENT LEDS A PEAK indicator and a SIGNAL PRESENT indicator are driven from the post equaliser signal. IC14 is used as a voltage comparator and directly drives leds 5 and 6. A reference voltage is applied to pins 5 and 7 while audio is applied to pins 3 and 5. The PEAK led comes on 3dB before clipping while the SIGNAL PRESENT led comes on with a signal level higher than -18dBu. THE AUXILIARIES With the exception of auxiliaries 7 and 8 the auxiliaries work in mono using mixed left and right signals which are derived either pre or post fade. The following three signals are available :PRE1, PRE2 and POST. PRE1 is the pre equaliser signal, PRE2 is the pre fader post cut signal and POST is the post fader post cut signal. When PRE is selected the PRE2 signal is the factory default setting. Links enable the default settings to be changed. AUX 1-3 Remove link 3 and install link 4 for PRE1. AUX 4-6 Remove link 6 and install link 7 for PRE1. AUX 7-8 Remove link 11 and install link 12 for PRE1. Auxiliaries 7 and 8 may be used as a stereo pair by depressing SW22, the STEREO switch. 23
THE CUT CIRCUIT LOGIC SW6 is the mechanically latching CUT switch which when operated places a ground on the cathode of D15 causing the base of Tr3 to go low and therefore the collector to go high. D9 will now stop conducting enabling LED1 to illuminate indicating a cut. The collector of Tr3 is applied via R118 and R98 to the gate of Tr1, an P channel FET, causing it to stop conducting hence muting the signal. D10 is used to create different on and off switching times for the FET. As the attenuation of the FET is not perfect a feedforward technique is used to cancel any residual signal. A small fraction of the channel signal is fed to the non inverting input of IC4A where it will sum with the residual but in anti-phase to it thus cancelling it completely. The operation of the AUXILIARY CUT is similar to that of the CHANNEL CUT. Links 1 and 2 exist to disable the auxiliary cut if required. In this case Link 1 should be removed and Link 2 installed. An external input and output are available for the CUT function. The external cut output simply extends a ground onto the connector when the cut switch is depressed. The external cut input requires to ground the cathode of D7 which then has the same effect as the cut switch grounding D6. A simple latching switch contact is sufficient. THE SOLO FUNCTION SW18 is the solo or PFL switch. When operated it places DC onto the IPCUEDC bus which is detected by the master module enabling it to replace the selected monitor signal with signal from the solo bus (IPCUE). The equaliser outputs are mixed to mono for use as the solo signal. If Solo In Place mode is selected then the module initiating the solo will have its solo switch depressed and the returned SIP signal from the master module will have no effect. If the module did not originate the solo in place the solo switch will not be depressed and the SIP signal will cause the channel to mute. Thus only the module initiating the solo will be left uncut. In this mode no change takes place on the master module and only the module initiating the solo in place will be heard through the monitoring system. There is provision for an external meter on connector CON4 (option). ROUTING AND GROUNDING All routing to buses is through 10k resistors. All connectors are grounded to the metalwork (chassis) ground. This is connected to 0V by a 100R resistor in parallel with a 10n capacitor. BUSREF is taken from 0V through a 10k resistor. 24

STEREO INPUT MODULE BLOCK DIAGRAM
THE GROUP OUTPUTS (CD1280/CD1286) There are two different kinds of output module. Numbers 1 - 6 carry a matrix section and auxiliary output while numbers 7 and 8 carry a stereo return section and an auxiliary output in addition to the group output stage. THE GROUP OUTPUT (CD1286) Links 1, 2, 3, 4, 14, 15, 24 and 25 determine which of the group buses will be assigned to the output. Only one link should ever be installed. IC7B mixes the bus signals and presents them to IC7A which simply phase inverts the signal before feeding the group insert point, CON4. This is unbalanced and the send signal is applied to the tip of the jack. When no plug is inserted the signal is normalled through the RING contact and sent to the group fader. This is followed by a buffer (IC8A) with 10dB of gain in order that the fader can be run with 10dB of gain in hand. A BUS PEAK indicator is fed from the pre insert signal to give warning of high signals on the group bus. D5 half wave rectifies the audio signal which is then presented to IC11B. This is used as a voltage comparator and drives LED13 when the signal exceeds the voltage on pin 6 of IC11B. Any signal greater than 3dB below clipping level will cause an indication. An AFL feed to the solo system is taken from the output of the fader buffer. It is fed to the OPCUE bus through switch SW9 which also applies DC to the OPCUEDC bus. The group signal goes to the MUTE switch, SW8, from where it splits off to the meter, the group output, and the sub mix circuitry. The balanced output stage built around IC10 will simulate a transformer so that it may be used into unbalanced loads without any ill effect. Links 7 and 8 are used to bypass the output transformer connector (CON10) and must be removed if a transformer is used. CON15 may optionally be fitted where the output is to be wired to a multipole connector. The meter is built around IC12, a BA683A, giving a 12 segment display with a range of +12dB to -21dB. PR1 is used to calibrate the 0dB point while PR2 is used to set the DC offset for the low end of the scale. SW1 selects the group or the matrix signal to the meter. Note that the BUS PEAK indicator is also switched between the group and the matrix. CON17 may optionally be fitted to provide signals for a meterbridge. CON17 is switched by SW1 to carry the group or the matrix meter signals. 27
There is a feed to an matrix connector (CON7) and links 5 and 6 determine whether the signal is pre or post fade. Link 5 is normally installed giving a POST FADER signal to the matrix. Link 13 is used to select the matrix bus. The group can be sub mixed onto the main L/R and centre buses of the console. A pan control is required to pan the mono group signal onto the L/R and centre buses and this is constructed around VR15, a dual pot, and IC9. When in L/R mode only one section of the pot is used and it simply reduces the resistance to ground of the left or right signal depending upon the direction of rotation. This reduces the amplitude of the signal on one side while increasing it on the other to create the panning effect. When LCR mode is selected the input signal is fed to a centre tap on the pot. Signal will thus only appear on the left or right output of this section of the pan circuit with the amplitude depending again on the rotation of the pan pot. The centre output is derived from the same input signal as the left and right outputs. VR15B is used to control the amplitude of the centre signal and it is buffered by IC8B. The output of IC8B is fed to the centre bus of the console when LCR mode is selected and the MIX switch, SW6, is pressed. The POST signal may be fed to the centre output of the console by pressing SW5 (MONO) which will over ride the centre output of the pan pot in LCR mode. AUXILIARY MASTER (CD1286) Links 9, 10, 11, 12, 20, 21, 22 and 23 determine which of the auxiliary buses will be sent to the output. Only one link should ever be installed. IC4B mixes the bus signals and presents them to IC4A which simply phase inverts the signal before feeding the auxiliary insert point CON11. This is unbalanced and the send signal is applied to the TIP of the jack through SUP11. With no plug inserted the signal is normalled through the RING contact and sent to the auxiliary master level control, VR1. This is followed by a buffer (IC11A) with 10dB of gain in order that the level control can be run with 10dB of gain in hand. An AFL feed to the solo system is taken from the output of the buffer. It is fed to the OPCUE bus through switch SW2 and DC is applied to the OPCUEDC bus. The buffer output feeds the balanced output stage built around IC6. This stage will simulate a transformer so that it may be used into unbalanced loads without any ill effect. Links 18 and 19 are used to bypass the output transformer connector (CON2) and must be removed if a transformer is used. Components labelled SUP are provided for the purposes of interference suppression and are fitted to all input and output connections. 28
CON16 may be optionally fitted to feed a meterbridge. THE MATRIX SECTION (CD1286) A 12 by 6 matrix is formed by output modules 3 through 8. The groups account for eight of the inputs with remainder being used by the left, centre and right mixes and an external input. CON12, a TRS jack, is used as the external input feeding IC1A which unbalances the signal and feeds VR2, the level control. The output of VR2 is combined with the group and mix inputs to the matrix at IC2A with IC2B being used to phase invert the group/mix signals which are simply brought in through level control pots VR3-VR10. The combined signal goes to the matrix insert point, CON3, before going through the matrix output level control, VR14. This is followed by a buffer with 10dB of gain allowing the fader to be used with 10dB of gain in hand. The output of the MUTE switch is used to feed the AFL switch, SW4, in addition to feeding the balanced output stage built around IC3. This stage will simulate a transformer so that it may be used into unbalanced loads without any ill effect. Links 16 and 17 are used to bypass the output transformer connector (CON9) and must be removed if a transformer is used. Components labelled SUP are provided for the purposes of interference suppression and are fitted to all input and output connections. STEREO INPUT (CD1280) The stereo input is a line level stereo input which can be routed to the group, auxiliary and mix outputs of the console. Note that if a mono input is available then only the left input need be used as it will be normalled to the right signal path if no jack is inserted into the right input. IC1 forms the stereo balanced input from where the signal goes through a gain control stage using IC2 and VR1 followed by the two band equaliser using IC3. The output of the equaliser is summed to mono to create the PRE-M signal used to feed PFL through SW8 and the auxiliaries. When SW8 is operated DC is fed onto the IPCUEDC bus to signal the master module that a solo has been requested and audio is placed on the IPCUE bus. The equaliser is followed by the MUTE switch, SW14, and from there the signal goes through a stereo fader. This is followed by a buffer stage with 10dB of gain in order that the fader can work with 10dB of gain in hand.
29
The post fader stage is presented to a balance control constructed around VR4 and is mixed to mono to create the POST-M signal used to feed the auxiliaries. The balance control is buffered by IC5 giving unity gain with the control in its central position. With the control rotated to the right, for example, the right signal will increase by 3dB while the left signal will be fully attenuated. The output of the buffer is fed to the MIX switch, SW2 and the group routing switches, SW4 through SW7. The feed to the mono bus is through SW3 using the POST-M signal. Auxiliaries 5 through 8 can be accessed by the stereo input. The PRE switch, SW1, allows the auxiliaries to be sent pre fade mono signal rather than the post fade mono signal. The STEREO switch, SW13, allows auxiliaries 7 and 8 to be used as a stereo auxiliary using either the pre or post fade stereo signals. THE GROUP OUTPUT (CD1280) Links 1 and 2 determine which of the group buses will be assigned to the output. Only one link should ever be installed. IC7B mixes the bus signals and presents them to IC7A which simply phase inverts the signal before feeding the group insert point. This is unbalanced and the send signal is applied to the TIP of the jack. When no plug is inserted the signal is normalled through the RING contact and sent to the group fader. This is followed by a buffer with 10dB of gain in order that the fader can be run with 10dB of gain in hand. A BUS PEAK indicator is fed from the pre insert signal to give warning of high signals on the group bus. D5 half wave rectifies the audio signal which is then presented to IC11B. This is used as a voltage comparator and drives LED18 when the signal exceeds the voltage on pin 6 of IC11B. Any signal greater than 3dB below clipping level will cause an indication. An AFL feed to the solo system is taken from the output of the fader buffer. It is fed to the OPCUE bus through switch SW12 which also applies DC to the OPCUEDC bus. The group signal then goes to the CUT switch SW10 from where it splits off to the meter, the group output, and the sub mix circuitry. The balanced output stage built around IC10 will simulate a transformer so that it may be used into unbalanced loads without any ill effect. Links 7 and 8 are used to bypass the output transformer connector (CON5) and must be removed if a transformer is used.

GROUP OUTPUTS 7-8 BLOCK DIAGRAM
THE MASTER MODULE The Master Module supports a number of functions including the main mix outputs, two auxiliary outputs, a tape return input and the monitoring system. Two circuit boards are used with signals passing between them when required. AUXILIARY SENDS (CD1281) Auxiliaries 7 and 8 are located on the master module and their function is identical to the auxiliary masters located on the group modules. Looking at Auxiliary 7 IC1A mixes the auxiliary 7 bus signals and presents them to IC1B which simply phase inverts the signal before feeding the auxiliary insert point. This is unbalanced and the send signal is applied to the TIP of the jack. When no plug is inserted the signal is normalled through the RING contact and sent to the auxiliary master level control, VR1. This is followed by a buffer with 10dB of gain in order that the level control can be run with 10dB of gain in hand. An AFL feed to the solo system is taken from the output of the buffer. This is fed to the OPCUE bus through switch SW1 and DC is applied to the OPCUEDC bus. The output of the buffer feeds the balanced output stage built around IC3. This stage will simulate a transformer so that it may be used into unbalanced loads without any ill effect. Links 1 and 2 are used to bypass the output transformer connector (CON13) and must be removed if a transformer is used. LEFT, CENTRE AND RIGHT MIX (CD1281/2) IC4A mixes the left bus signals and presents them to IC4B which simply phase inverts the signal before feeding the auxiliary insert point. This is unbalanced and the send signal is applied to the TIP of the jack. An unbalanced feed to a tape recorder is also taken from this point and is suitable for machines operating at -10dBV. A feed of the CENTRE or MONO mix is also summed with the left and right signals for sending to the tape recorder outputs. When no plug is inserted in the insert jack the signal is normalled through the RING contact and sent to the master fader. A BUS PEAK indicator is fed from the pre insert signal to give warning of high signals on the master bus. D11 half wave rectifies the audio signal which is then presented to IC7A used as a voltage comparator to drive LED13. Any signal greater than 3dB below clipping level will cause an indication.
35
The master fader is followed by a buffer with 10dB of gain in order that the fader can be run with 10dB of gain in hand. The output of the buffer feeds the balanced output stage built around IC8. This stage will simulate a transformer so that it may be used into unbalanced loads without any ill effect. Links 3 and 4 are used to bypass the output transformer connector (CON14) and must be removed if a transformer is used. A feed of the fader buffer output is also used to feed the centre output of the console when SW8 is depressed. The signal paths for the RIGHT and CENTRE signals are identical to that described for the left signal. MONITORING There are left, centre and right outputs for speakers, a stereo headphone output and 3 master meters. Solo audio is automatically switched on to the monitor outputs when a solo is active and there is an external tape input which can be assigned as a monitor source or to the left and right outputs of the console. TAPE PLAY INPUT (CD1283) The external tape input is unbalanced and buffered by IC5 having a non inverting gain of 5.5dB. The signal passes through CON11 (CD1283) to CON10 (CD1282) and from there to the level control VR2. The inputs to the level control are also taken to the TAPE switch SW6. The outputs of the level control feed IC13 which has 6dB of gain before being presented to switches SW2 and SW3 which route it the L/R and MONO outputs of the console. The signals are applied to the fader buffers and hence the master faders will not affect the level of the tape signal when assigned to the mix outputs of the console. This means that a tape can be played through the console outputs with the main faders closed to suppress other signal sources and is known as an intermission playback facility. In addition to the TAPE switch the monitor path has a MIX TO MON switch (SW4) and a CENTRE TO MON switch (SW5). The selected source is applied to fets Tr1, Tr2 and T18 which will normally pass the signal. If a solo is active then Tr1, Tr2 and Tr18 will cease to conduct and Tr3, Tr4 and Tr19 will conduct to allow the solo bus to be fed to the monitor outputs of the console. LMON, RMON and CMON are the signals presented to the monitor outputs. SOLO LOGIC (CD1282) There are two solo DC buses, IPCUEDC and OPCUEDC which allow input and output solos to be treated differently. If an input solo is requested the IPCUEDC bus will go high causing Tr7 to turn on and hence its collector to go low. 36
This switches off Tr8 which allows Led 16 to turn on indicating an input solo. The collector of Tr7 is connected through SW7 (the SIP switch) to the gate of Tr6, causing Tr6 to switch off. The effect of this is to disable any output solo audio that is active, giving the console input solo priority. The cathode of D7 is now low causing Trs 1, 2, 12 and 18 to turn off. Tr11 inverts the output of Tr7 causing Trs 3, 4, 13 and 19 to turn on. Thus the normal monitor source is silenced while the solo audio is allowed onto the monitor outputs in addition to the left meter now showing solo audio level instead of the left mix signal. The operation of an output solo is very similar other than for the fact that it cannot disable input solos. During a solo the centre and right meters are muted by fets Trs 5 and 6 (CD1283). Solo audio is mixed by IC11B and this is where the solo meter feed is derived. Signal can be adjusted in level by VR3 before going to the monitor system without affecting the meter readings. A Solo In Place mode can also be selected and when this is the case the output of Tr7 feeds Tr14 causing it to turn on and therefore Tr15 to turn on. This causes a logic low to be placed on the SIP bus which mutes any input module not having its solo switch depressed. The master meters are built around BA683A ICs, giving a 12 segment display with a range of +12dB to -21dB. Auxiliary 8 and the centre output are as for auxiliary 7 and the left output description previously given. THE MONITOR OUTPUTS (CD1284) The selected monitor signals LMON, RMON and CMON are fed to a volume control VR4 which is buffered by IC10/11. A PHONES switch (SW14) selects the headphone or loudspeaker outputs. The loudspeaker outputs are built around IC12, IC13 and IC14 and are similar to the balanced outputs used for the main outputs of the console. Transformer balancing is not available for the monitor outputs. The headphones outputs are designed to feed a low impedance load and have a transistor output stage. IC17, transistors 1 through 4 and associated components form the stereo headphone amplifier. TALKBACK IC15 is the talkback microphone amplifier with gain being adjustable by VR3. Link 1 may be installed if a phantom powered microphone is to be used. When the talkback key is pressed Rs 114, 115 and 116 connect with the monitor signals to form a DIM circuit of around 15dB. 37
Talkback can be routed to the auxiliaries, the mix or the groups. There are also sine and pink noise generators. They can be switched on using SW7 and the appropriate source selected by SW6. The routing for these generators is as for the talkback. VR2 is a level control for the selected oscillator. Pink noise is generated from diodes D16 and D17 which are differentially applied to IC7A. The output from IC7 is taken through the ON switch, SW7, and then applied to IC7B for amplification before filtering by resistors R86—R91 and capacitors C45—C49. The output of the filter is buffered and amplified by IC6B from where it goes to the SINE/PINK selector switch, SW6. A 1kHz sine wave is generated by IC16 with D18 and D19 being used to stabilise the amplitude. IC16A along with C53, C54 and R97 form a bandpass filter determining the frequency of oscillation.

MASTER MODULE BLOCK DIAGRAM
THE BUS LINKING PORT The bus linking port enables two consoles to be used together in a master slave configuration. The bus structure is broken between the input modules and the group modules although in normal use a shielded connector is used to join the two sections. If the console is to be used as a master the connector is removed and the master end of a link cable put in its place. This retains the link between the buses and connects the input modules of the slave console to the buses of the master console. If the console is to be used as a slave the slave end of the link cable is used which breaks the link between the buses and feeds the input modules over to the master console. This of course means that the group and master modules of the slave console are not used as only one master per function can be allowed access to the bus. During unlinked operation a blanking plug must be inserted to connect the input and output buses. CD1308 This shows the Bus Link Blanking Plug. CD1306 This shows the Bus Link PCB. There are two input connectors to allow consoles where the master modules are located in the centre. and one output connector. The output and input connectors are connected by the blanking plug during normal (unlinked) operation.

THE METERBRIDGE VU METERBRIDGE (CD1310) The VU Meterbridge carries 11 meters indicating the three main console outputs in addition to either the matrix, group or auxiliary outputs of the console. Signal selection is carried out by switches SW1 — SW3 while C1 ensures that on power up the GROUP signals will be displayed. IC1 is a dual SR Flip Flop and normally the Reset input will be held low by the pull down resitor R3. The Set input is wired to Vss and is thus always low. When SW1 is pressed, or C1 is charging immediately after switch on, Vdd is connected through D1 and R3 to Vss. Current therefore flows and a voltage is created across R3 which is enought to make the Reset input if IC1a see a logic high. The Q output is thus set to a logic low while the Qbar output will be a logic high. A similar situation will arise on IC1b and therefore the A and B control inputs of the 4052 multiplexers will both be low allowing the X0 and Y0 input signals through which are the group signals. IC12a also reads the control lines. As both are low and the IC is connected as an invertor the output will go high causing LED1 to illuminate. If neither or only one of the control lines is low the output will not go high enough to turn on LED1. If the matrix output is required then SW2 should be pressed. This will cause C2 to charge through R1 creating a +ve pulse on the clock input of IC1A. Assuming that we are in GROUP mode the Data input will see the logic high from the Qbar output and this will be clocked through to the Q output. The A control line now goes high while the B control line stays low causing the multiplexers to allow through the signals on the X1 and Y1 inputs which are the matrix signals. If the auxiliary outputs are required then SW3 should be pressed. IC1B is clocked by a +ve going pulse from C3. Again the Data input which is high will be clocked through to the Q output causing the B control line to go high. The multiplexers will now allow through signals connected to the X3 and Y3 inputs which are the auxiliary output signals. The B control line is connected through to the RESET pin of IC1A and when the auxiliary signal is selected a pulse will be created through C6 causing IC1A to reset. When the auxiliary signals are deselected the B control line will go low causing a -ve going pulse. To prevent this from causing damage to the circuit components it is clamped by D3 and thus prevented from driving the reset pin more than 0.6V below ground. C7 and D4 perform similar functions on IC1B.
43
When the A control line is high the output of IC11b will go low causing the MATRIX indicator to illuminate while if the B control line is high the output of IC12b will go low causing the Auxiliary indicator to illuminate. The outputs of the multiplexers are fed through buffer amplifiers with some gain adjustment to allow for calibration of the meters. Resistors attenuate the signal input to the multiplexers when a signal is not selected in order to prevent breakthrough of any high level audio signals. The signals for the left, centre and right mixes do not travel through any multiplexers and are permanently selected. There are of course only 6 matrix outputs and meters 7 and 8 will therefore not indicate during the period that the meterbridge is being used to indicate MATRIX signals.
LED METERBRIDGE OUTPUT SIGNAL PROCESSING (CD1312) The signal input to the led meterbridge output section is identical to that of the VU meterbridge. Selection can be made between the group, matrix and auxiliary signals. In this case the outputs from the multiplexers are fed to quad comparator ICs of the type LM2901. These rectify the audio signals and define the ballistics of the resulting signal that is fed to the display board (CD1311). LED METERBRIDGE OUTPUT DISPLAY BOARD (CD1311) Each meter is identical and is constructed from 3 quad comparator ICs of the type LM2901 creating a 12 segment meter. A resistor chain is used to set the threshold voltage for each comparator and this determines the point at which an led will switch on. The leds are driven from constant current sources formed from transistors TR1 through TR8. LED METERBRIDGE INPUT DISPLAY BOARD (CD1307) The meteres are identical to those used on the output display board (CD1311). There is no need for a ballistics and rectifier section in the meterbridge as the signal is taken from after the ballistics and rectifier section of the meter driver on the module. Further LM2901 ICs (IC25 and IC26) are used to buffer the module signals before being presented to the meters.

THE POWER SUPPLY The power supply is a linear type supplying +/-18 volts and +48 volts DC to the console. It may be rack mounted and a space of 2U above the unit is recommended for ventilation. The positive and negative rail regulators are identical in operation thus only the positive rail is described. Diodes D11 through D14 rectify the incoming AC from the transformer and feed the main reservoir capacitors C9 and C10. A small plug in module contains the series pass transistor and associated regulating circuit. Q002 is the series pass transistor and is driven from Q001 which in turn receives a control signal from IC001, a 723. The output from the series pass transistor is passed directly to the power supply output. D15 indicates that the supply is functioning. Diodes D1 through D4 rectify the AC used for the phantom voltage supply. This is smoothed by C1, C2 and C4 from where it is fed to a TL783C, the regulator. R1, R2 and R4 are used to derive a programming voltage which is applied to the TL783C. D5 and D6 will protect the regulator from inverse voltages that may be applied to it. C5 and C15 smooth the regulated output which is applied to the output connector of the power supply. D7 indicates that the phantom supply is working. There is a delayed output from the power supply which may be used to activate relays in a console. This facility is not used when connected to the CS8 console. There is no connection within the power supply between 0V and mains earth (chassis). There is a ground lift switch which, when operated, will allow the console to float completely free from ground. If the ground is lifted then the console chassis is connected to 0V Audio in the power supply. DC Pinout 1 2 3 4 5 6

SERVICE INFORMATION With the exception of the meters there are no adjustments within the CS8 console. SAFETY Always switch off the console before carrying out any work on it. TOOLS No special tools are required in order to service the CS8. An oscilloscope and multimeter will allow fault finding to component level in the unlikely event of a fault. A module extension cable, ACBL99-023, is supplied with the console to enable individual channels to be powered when removed from the frame. If a complete block of 8 channels is to be serviced then ACBL99-024, an 8 way extension cable, should be used. MODULE REMOVAL Remove the twelve screws retaining a module and ease it out of the frame. There are four screws at the bottom of the module, four screws at the top of the module and four screws at the rear of the console at the base of the connector panel. The recommended method is to raise the front of the module and to push the module a little towards the front of the console from the rear connector panel. Lift the module, holding it at the front edge and rear connector panel. Keep it parallel to the front plane of the console and disconnect the ribbon cable from each of the 8 boards before pulling the module completely clear. MODULE DISASSEMBLY Remove the screws mounting the XLR to the connector panel. Remove the screws holding the circuit board to the top panel and pull the circuit board clear. MODULE REASSEMBLY This is a reverse of the disassembly process and care must be taken that leds are not damaged through misalignment with their panel holes. MODULE REPLACEMENT Place the module over its final position and reconnect the ribbon cable to all the boards. Gently ease the module back into the frame taking care not to crush or otherwise damage the ribbon cable. Insert the 12 retaining screws. STATIC PRECAUTIONS Electronic equipment can be very sensitive to static discharges and care should be taken to avoid static in the work area. Where possible work on a bench where you can be grounded through a wrist strap. 58
If boards have to be shipped then they should be wrapped in conductive plastic bags or conductive plastic sheeting. PARTS In the interests of safety always use genuine replacement parts. Safety approvals will be invalidated by use of non standard components. METER ALIGNMENT An audio test set is required to accurately measure the level of the output for which the meter is being adjusted. Master Left and Right Meters With 0dBu at the console outputs adjust PR1 to read 0dB and with -21dBu at the console output adjust PR2 such that the bottom led is just on. These adjustments should be repeated until both readings are accurate as they are interactive to some extent. Centre Meter PR15 should be used to set the 0dB point while PR25 should be used to set the -21dB point following the above procedure. Group Meters PR2 should be used to set the 0dB point while PR3 should be used to set the -21dB point following the above procedure. If a meterbridge is fitted then some additional calibration work will be required as follows:VU Bridge Calibrate the console meters as above and then use PR1 through PR7 to calibrate the VU meters. The adjustment is the same for whichever signal source is selected and it is therfore probably easiest to set the meters to read GROUP. Set the group outputs to +4dBu (0VU) and adjust PR1 for group 1 so that the meter reads 0VU. Calibrate the remaining meters using PR2 through PR8. The master meters can be set in the same fashion having set the output levels to +4dBu. PR9 will calibrate the left meter while PR10 and PR11 will calibrate the centre and right meters respectively. LED Bridge There are no adjustments in the led meterbridge.
