Module A-132-1 contains two voltage controlled amplifiers, with a linear response most suited to regulating the level of control voltages (ADSR amount, level of vibrato effect, etc.). In non-critical situations, though, its VCAs can be used to control audio signals. Amplification is governed by the sum of the voltages patched into the two CV inputs.

Technical notes:
The A-132-1 is able to process even slowly varying control voltages (DC coupled in/outputs).
Since June 2013 the A-132-1 is equipped with SSM2164/V2164 (instead of two CA3080). Unfortunately it's not possible to upgrade older modules because the new circuitry is totally different.
