mfb vca price : $110.00

the vca (voltage controlled amplifier) module is a classic amplifier to control audio- and cv-signals.

mfb-vca offers three inputs, of which input 1 can be continuously attenuated. inputs 2 and 3 offer no attenuators but different sensitivities. they are intended as alternatives for different signal sources rather than to be mixed.

both cv-inputs can be adjusted in amplification. an envelope generator will typically control cv-1. a distinctive feature for cv-input 2 is its dependency to cv-input 1. only if voltage is applied to cv-1, any cv-2 control becomes active. a typical application would be a dynamic tremolo effect: with cv-1 under envelope control and cv-2 under lfo control, the tremolo will only be audible with a note held. typical parallel cv-inputs found in other modules would need a second vca-module to achieve this effect.

there are two parallel outputs: output 1 has fixed level and output 2 offers variable attenuation.

the module has a width of 40 mm (8 te).
