Abstract Data ADE-50 3x VCA

Name: ADE-50 3x VCA
Brand: Abstract Data

3 Linear VCAs based on a discrete OTA core.

4 HP Eurorack module

A compact three-channel analogue VCA module. Each channel uses a 0–5V control-voltage input to set attenuation through unity gain.

Features

Three all-analogue linear VCAs based on discrete OTA cores.
DC-coupled signal paths handle audio, fixed DC voltages, LFOs, and envelope CV.
Remember: allow about one minute for the discrete VCA cores to settle to optimum gain and offset after power-up.

CV Input 1— 0–5V control-voltage input for VCA 1; 0V attenuates fully and 5V gives unity gain.
Output 1— DC-coupled, voltage-controlled output of VCA 1.
Signal Input 1— DC-coupled signal input for VCA 1; accepts audio, fixed DC voltages, LFOs, and envelope CV.
CV Input 2— 0–5V control-voltage input for VCA 2; 0V attenuates fully and 5V gives unity gain.
Output 2— DC-coupled, voltage-controlled output of VCA 2.
CV Input 3— 0–5V control-voltage input for VCA 3; 0V attenuates fully and 5V gives unity gain.
Signal Input 3— DC-coupled signal input for VCA 3; accepts audio, fixed DC voltages, LFOs, and envelope CV.
Signal Input 2— DC-coupled signal input for VCA 2; accepts audio, fixed DC voltages, LFOs, and envelope CV.
Output 3— DC-coupled, voltage-controlled output of VCA 3.
