Dual Linear / Exponential Voltage Controlled Amplifier
The A-132-3 is composed of two identical voltage controlled amplifiers (VCA). Each VCA has a manual gain control and a control voltage input with attenuator.
The character of the control scale can be switched to linear or exponential. All inputs and outputs are DC coupled. Consequently the VCAs can be used to process both audio and control voltages.
The input has no attenuator available but is capable to process up to 16V signals (i.e. -8V...+8V) without distortion.
After September 2010, the A-132.3 was redesigned from using the now unavailable CEM3360 VCA chip, to the new SSM2164 chip, which can produce a greater amplification, allowing the A-132.3 to be overdriven easier.
