Erica Synths Black Quad VCA2 is a versatile four channel voltage controlled amplifier and mixer module for use in complex modular systems. Each channel has linear/logarithmic response selector and signal level indicator LED. All outputs are sequentially mixed and CV inputs are normalled to each other, so you can use the module in various configurations. If no CV is applied, the Black Quad VCA2 performs as a signal mixer, and the 4th channel is DC coupled for controlling CV sources, as well.

Features:
4 independent VCAs 
Selectable lin/log response for each channel 
Manual CV bias and signal level adjustment 
Sequential output mixing 
Signal level indicator LEDs

Technical specifications:
CV level: -10V – +10V
Attenuation level: 
CV = 0V (max attenuation) -80dB
CV = +10V (unity gain) +3dB
Response lin/log
