VCA and Mixer Modules

Pittsburgh Dual VCA

The perfect voltage controlled amplifier for both audio and CV applications. Dual, high quality linear voltage controlled amplifiers with both offset gain, CV attenuation, and a mix out. Each VCA includes a CV attenuators and input pass through attenuator. The output of each VCA is sent to a fully buffered mix output that allows the Dual VCA to act as two channel voltage controlled mixer.

Pittsburgh mixer

A flexible, low-noise four channel mixer and/or attenuator for audio and cv that can be used in several ways.  Three of the four channels have an output that removes the channel from the mixer circuit and allows it to become a standalone attenuator.

PITTSBURGH MIxmult

The MixMult is a multifunction utility module. The module combines three important functions into a single module. A high quality three channel mixer and/or attenuator and two sets of passive multiples.
