1. Introduction
Module A-135 (VC-Mixer) is a four-channel voltage
controlled mixer, which is used to mix audio signals
with four independent voltage controlled levels.
The module consists of 4 linear voltage controlled
amplifiers (VCAs) mixed to one common output. High
quality integrated VCAs (CEM3381) are used in the
circuit.
Each VCA has the following:
• Audio input with attenuator
• Control voltage input with attenuator
• Gain control (amplification offset).
