A-138U Dual Micro Mixer

Doepfer A-138U

Doepfer’s A-138U is a space-efficient, low cost 3:1 mixer module with dual channels. The output of the upper section is normalled to the first input of the lower section, enabling one to use the module as a 5:2, with the sum of all five signals being sent via the bottom output.

A-138U Features

• Mixer for audio signals, e.g. three VCOs preceding a VCF, when the amplifications are adjusted slightly different no signal extinction occurs during the beat of the VCOs
• Mixer for control voltages (e.g. LFOs, envelope generators, random voltages)
• Combined with an attenuator bank, a full function mixer is available
• DC Coupled - works with audio rate and control signals
