Switched On - Doepfer A-135-1 VC Mixer Module

Doepfer A-135-1

Regular price $125.00

This A-135-1 V1 is fully functional and in very good condition.

Module A-135-1 is a quad voltage controlled mixer. It is made of 4 independent linear VCA's. The VCA outputs are mixed to a common output. For each VCA the following inputs and controls are available: audio input with attenuator, control voltage input with attenuator, gain (pre-amplification). The VCA's are realized with high-quality CEM VCA's (CEM3381 for version 1 and SSM2164 for version 2).

Applications: voltage controlled mixing of up to 4 audio signals with separate control voltages (e.g. delivered by LFO's, ADSR's, Random, Shepard generator, MIDI-to-CV interface or other control voltage sources). In connection with the Morphing Controller A-144 the soft fade-over of 4 audio signals with only one control voltage is possible.
