This is dual voltage controlled amplifier. Both can be used independently, as cross-fader or panning amplifier. VCA core is made with discrete transistors.

INITIAL 1,2 knobs:

ammount of initial amplification for each amplifier (without external CV)

PAN knob:

controlls amplification difference between both VCAs

LIN/LOG switches

toggle VCA control response between linear and log (dB-like)

CV1, CV2 knobs:

attenuators of external control voltages for individual VCAs

CVX knob:

attenuator of externall x-fade/pan control voltage

Other two switches

change module function: dual VCA, cross-fader, panner, and couple two control inputs, which can affect VCAs independently, or both at the same ratio.

INPUTS:

IN1, IN2, CV1, CV2, CVX

OUTPUTS:

OUT1, OUT2
