4VCA 31A

The 4VCA 31A is 4 individual high quality low noise linear Class A VCAs in a single space module. The 4VCA is also an excellent voltage controlled 4 x 1 sub-mixer or optionally configured as a voltage controlled CV processor.
An essential module for medium to large systems.

Three possible configurations are available:
Config 1- the VCA inputs are capacitor coupled for minimum offset feed through, for audio only with no 'thumping'.

Config 2- the VCAs are set for unity gain with no capacitor
coupling for voltage processing applications. This config can be used with audio too but fast attack times can introduce 'thumping' with signals containing DC-offsets.

Config 3- pull pot switches (switch is part of the gain potentiometer)
Permits individual selection for audio or CV processing.

Please specify when ordering.
Add $50 for optional switch option.
