Erica Synths Black Quad VCA, despite its compact size, is designed in line with the Black Series Hi-Fi philosophy, our custom pre-emphasis – de-emphasis circuits preserve all the nuances of the original signal. 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

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.

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, we did not economise on the module width, we put design and usability first. Big knobs are assigned to functions that make difference in sound. Together the Erica Black series are a range of modules that make an entire synthesizer.
