INPUT MODULE MODEL CS 208 v2 Left Section 1. CH: Channel Power (down = on) Do not switch during recording. 2. PH/DYN/T: Phantom power, no mic power, T (AB) power (Phantom power is normally 48 v, see layout A to change to 12 v). 3. ø: Phase (audio only). ø = normal phase, REV = reverse phase 4. Mic/Line: Microphone or line level in. 5. Pad: Attenuator to reduce either mic or line input levels. 6. HP 1: High pass filter, pre-transformer. 7. HP 2: High pass filter, post transformer & preAmps.
INPUT MODULE MODEL CS 208 v2 Right Section 17. Gain: Mic/Line preamp gain. 18. HF: High frequency amplitude control. 19. MF 500, 5k Mid-frequency select. 20. MF: Mid-frequency amplitude control. 21. N/S: N = normal, S = side for M/S decoding. ‘S’ inverts phase to B & D busses allowing one pair of channels to be used with a M/S mic configuration and decoded to a L/R stereo signal (this is an option, see separate application note). 22. LF: Low frequency amplitude control. 23.
OUTPUT MODULE MODEL CS 208 v2 Monitor 2 & 3 1. DIR/TAPE: Selects direct or tape return signals (for busses ABC & D). 2-7. A,B,C,D,A1,A2: Assigns busses to Monitor 2/3 outputs (L) = left, (R) = right when using stereo headphones. 8. M/ST/MS: M = mono, ST = stereo, MS = mid-side. Only applicable if stereo headphones are used. (See rear panel) 9. LEVEL: Gain Adjustment. Aux 1, Aux 2 10,11.: Aux 1 & 2 master level controls. 12. BNC: 12 volts available to power a ‘Littlite’® (See meter panel). 13.
OUTPUT MODULE MODEL CS 208 v2 20. SOLO/OFF/ON A,B,C,D,A1,A2: 21. M/ST/MS: (Monitor 1) Any combination of busses can be monitored. ’SOLO’ disconnects the otherbusses to the Monitor 1 output - Solo normally mono’s the signal to the headphone out - there is an internal slide switch to defeat this. ‘ON’ - In stereo mode the busses are assigned to either (L) left or (R) right. M = mono, ST = stereo, MS = mid-side Any combination selected by switch (20) can be monitored in mono, stereo or mid-side. 22.

MODEL CS 208 v2 BASIC SET-UP Nominal value of 47kΩ to 56kΩ in series with signal conductors.
OPERATIONAL & APPLICATION NOTES MODEL CS 208 v2 Inputs: XLR In: Transformer balanced input. Nominally Pin 2 high. (Pin 3 - low, Pin 1 - ground). Channel Power: To conserve current consumption, switch off unused channels. Do not switch during recording. Mic Power Select: Mic power off. For example, dynamic and radio microphones. T-power / AB power = Unbalanced microphone powering, nominally Pin 2 is positive, for use with unmodified European microphones. XLR must be reversed for ‘red dot’ microphones.
MODEL CS 208 v2 OPERATIONAL & APPLICATION NOTES Limiter: Attack and release times are preset internally. Threshold: Limiter threshold adjustment. (See application note AN 2D v2) The LED adjacent to the limiter switch indicates limiter action. PFL/AFL: Selects prefade listen or after (post) fade listen. All other inputs to monitor 1 will be disconnected (except private line and communication in). The LED indicates whether PFL or AFL is selected as the switch is not momentary.
OPERATIONAL & APPLICATION NOTES MODEL CS 208 v2 Insert: Post HP filters, EQ. & Limiter. Send and return to auxiliary equipment. (eg: Outboard compressor / limiter, equalizers and multi-track recorders). Can be changed to Direct out, Prefader only. (See application note AN 2A & 2B v.2) Direct Out: Post channel fader. (eg: feed to playback systems. Direct feed to multi-track recorders) See balanced out option for pre or post fader outputs. 2 Holes above Ch.
MODEL CS 208 v2 OPERATIONAL & APPLICATION NOTES T/D (tape, direct): Tape return to monitor 1. Comm. in: Comm. return level controlled by trimmer below. ‘PL’: Assigns PL to monitor 1 (Down = on) Phones select: M = Mono ST = Sereo MS = Mid Side Monitor pots 1, 2, 3: To adjust level to phones 1, 2, 3 (stereo output). Caution: It is recommended to set the ‘phones’ pot at minimum before wearing headphones. Then increase the level to suit personal preference.
OPERATIONAL & APPLICATION NOTES MODEL CS 208 v2 Monitor 2 & 3 Expanded monitor selection - includes tape return and M/S decoding. All mix buses can be assigned independently. M/ST/MS - Mono, stereo, or MS decode. Note: CS 208 D chassis also has a mono/stereo switch on the rear panel, to enable both mono or stereo wired headphones to be used. In Mono (rear panel switch), the L & R outs are fed to the tip of the 1/4” stereo jack socket. The ring is not connected, so a mono plug can be used.

AN 2B v2 INPUT CHANNEL OPTIONS MODEL CS 208 v2 Direct Out, Pre - Fader Level Boost The nominal level of the Insert jack send/direct out, prefader, is -11dBu. If the insert jack function has been changed to direct out, prefader, (see AN 2A), the level can be increased 9dB. (see note 1) An op. amp. (TL071) needs to be plugged into U4 on board A to enable this feature. (This component is not normally installed to conserve current consumption.
AN 2C v2 - INPUT CHANNEL OPTIONS MODEL CS 208 v2 Mic Power See layout A, J8. Normally set for 48v phantom. Move both shunts to the left for 12v phantom power. The 12T power is not affected.
MODEL CS 208 v2 AN 2D v2 - INPUT CHANNEL OPTIONS Limiter Threshold Threshold - normally set at +4 PPM, with the input fader a ‘0’. Limiter Threshold Adjustment (no external test equipment required.) * Assign oscillator to C,D only (or Aux only). * Switch input channel to Line in. * Switch out C,D from the mix bus on input channel & turn off Aux sends. * Connect C,D or Aux outs to the input channel (short mic cable). * Pan L or R for A,B busses & switch off limiter. * Set input fader at ‘0’.
AN 2E v2 - INPUT CHANNEL OPTIONS MODEL CS 208 v2 M/S Decode Option See layout B. One or more channels may be set up to decode an M/S mic configuration. An op. amp. (TL071) needs to be installed on board B, U2 (on an even numbered channel). Jumpers on J3 need to be moved to the right position. Normal Side J3 J3 Switch ‘s’ (side) Left = Normal phase (no decode). Right = Reverse phase (M/S decode).
