15.COMMUNICATIONS TRIMMER: To adjust level of communications signal.
16.COMMUNICATIONS ON/ OFF: Communication input is fed only to "phones." (Line level input)
(eg: Boom operator talkback or cueing)
17. MUTE ON: In "on" position both monitor A & B outputs are muted during slating
and oscillator operation. An internal circuit board switch disables
muting function to monitor A output.
18. SLATE INTERNAL /EXTERNAL: External slate mic may be connected to the slate XLR. Level is
adjusted by (34)
19. "METER" AUTO /LEFT RIGHT: In auto, the meters follow the “phones”selection. ie:Mono / stereo,
L/R, Aux., PFL, Tape/Direct, L only, R only. In the L/R position the meter
indicates left and right signals, controlled by switch #20. (Tape direct)
20. "METER" TAPE /DIRECT.
21."PHONES" AUX. /LEFT RIGHT: Auxiliary signal is fed to both left and right "phones" outputs.
22. "PHONES" TAPE /DIRECT.
23. "PHONES" LEFT,MIX, RIGHT: With switch (21) in L.R., either left only or right only or both are fed
to"phones" outputs.
24. "PHONES"MONO / STEREO.
25. "PLAYBACK: Assigns tape return to monitor A & B outputs.
26. LEFT TAPE RETURN: Level adjust for tape return.
27. RIGHT TAPE RETURN: Level adjust for tape return.
28. PRIVATE LINE: Either internal or external slate mic output is fed to monitor A output.
(Can also be assigned to monitor B, see page 16).
29. PRIVATE LINE LEVEL: Independent of slate level.
30. OSCILLATE ASSIGN: Aux only, L/R only, all outputs
31. OSC. ON: Three-position switch; Up=On Center=Off
Down=Momentarily on
Level is dependent upon master fader positions.
32. OSC. FREQUENCY SELECT: Note: Also controls the frequency of the auto end tones.
33. INTERNAL SLATE MIC.
34. SLATE LEVEL: Controls both internal and external slate levels.
35. OSCILLATOR LEVEL.
36. SLATE ON: Three-position switch; Up =On(no sub-tone) Center=Off
Down=Momentarily on (with subtone)
Also, turns remote roll on (internal switch to defeat, see page 16).
37. ROLL ON LED.
38. ROLL ON: Roll is connected to the tuchel connectors to turn on either a Nagra
4.2 or IVS or both. When the roll switch is turned to off, the recorder will
remain on for ≈1 sec.and two end tones are fed to outputs. This
function can be defeated by a dip switch inside. (See location
diagrams, page 16).

enables module to be used as a single mono channel. By switching
the unused channel out there will be no additional noise contributed
to the other mix bus.
Ex. 2 As above, with right mic.
Ex. 3 Both inputs are fed to their respective outputs.
Ex. 4 Both module outputs are centered (ie; they are combined and fed
equally to both left and right mix busses and outputs).
Ex. 5 Both outputs are disconnected from the mix busses and fed only to
the module line outs.
(To enable a discrete mix to be made on a separate recorder.)
Ex. 6 As above, but both outputs are combined as in Example 4.
Ex. 7 Left output only is assigned to both left and right mix busses and
outputs.

AUX MODULE MODELS: CS 106+1
CS 108+1
COOPER SOUND SYSTEMS, INC. ■ 1067 MAIN STREET ■CAMBRIA, CA 93428 ■[phone]
A modular unit that can be installed in the Cooper series 100 location mixers. This
module provides two extra independent balanced outputs (Aux I, I I) that can
be utilized for four track recording (eg; Nagra D), two stereo mixes or additional
aux. sends.
The CSD-2 includes two P&G faders that are aligned with the existing two output
faders on the master module for easy group fades. Any input channel can be
selected or assigned to the CSD-2 outputs via the aux. module channel select
switches and the pan pots. The aux. outputs can be monitored by the 'phones'
and 'meters' on the output module by selecting 'I, II' on the module.
Mix bus switch on input channels - when switched 'off' the channel line out will
only go to the aux. module outputs allowing separate mixes to be made
independent of the main L, R outputs.
The slate and oscillator from the master module is also connected to the aux.
outs (internal dip switches can defeat this feature). The outputs are via a 5-pin
XLR connector mounted on the rear panel. Adapters to 3-pin XLRs are available.
Pin configuration is standard. (See specifications)
As with all other Cooper Sound products, all components are the best available
to ensure the highest audio quality and reliability in the field.
