Doepfer A-135-1

Module A-135-1 is a quad voltage controlled mixer. It is made of 4 independent linear VCAs. 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. Inputs: 4 x Signal in, 4 x CV In Output: Signal Out, Version 2 in addition: 4 x Single Out Controls: 4 x Signal In Attenuator, 4 x CV Attenuator, 4 x Initial Gain • 18 HP
