Behringer CP35 Attenuators

Very useful sub control CV line.

This module divide 3 areas.

Upper area is ATTENUATORS,

This area function same to "995 ATTENUATORS" , but this CP35 has 4 volumes and outputs.

Normally use Attenuators, input signal add upper left side inputs, and return each gain down control voltage with volume, and output to down side .

Next one is CP35 only.

If you want to change the control voltage BASE LINE voltage to UP or DOWN, you patch -6V or 6V to OUTPUTS connector, you can change the control voltage center up to 6V and down to -6V.

This function create a new sound effects.

(some module has electric crash from outside HIGH voltage, please check and use carefully. As your own risk.)

Good Replica

The attenuators are bidirectional (this is not obvious). However there are only two each of the -6V and +6V outputs. I use the -6V output to bias my 921 Oscillator or 921A Oscillator Driver so that the control knob is closer to zero when summed with the keyboard CV. The multiples are handy.

I do wish that the voltage bias outputs were independently buffered.

Obviously there is space on the panel for more functionality, but this is supposed to be a Moog System 55 replica so not so much. Therefore instead of knocking off 2 feature stars I only knocked off 1.
