If only CV IN 1 is connected it will control all 4 channels. Each CV input has an associated CV LED which lights green for a positive CV (VCA gain) and red for a negative CV (VCA attenuation), if the CV IN voltage is 0V then the LED does not light. (2) CV ATTENUATOR - Each channel has a CV Attenuator, which can reduce the CV input signal level when moved CCW. (3) BOOST - Each channel has a switchable Boost control, which raises the input gain by +6 dB when the switch is set in the right-hand position. (4) CURVE - Each channel has a continuously variable VCA response curve, ranging from exponential at full CCW to linear at full CW. (5) LEVEL - Each channel has its own overall VCA output level control. The response of the Level control is affected by the Curve control setting. (6) INPUTS - Each channel has its own input, which can be used with audio or CV input signals. (7) OUTPUTS - Each channel has its own output, which is mixed with channels to the right if no output cable is inserted into that channel output. If only the 4/ Mix output jack is connected the module operates as a 4 into 1 mixer, which can be operated manually using the Level controls, or voltage controlled via the CV inputs.
