Doepfer A-132, Dual VCA@+The module A-132-1 contains two voltage controlled amplifiers with a linear characteristic, which are mainly designed for controlling the amplitude of control signals (e.g. for ADSR-height, in/out-swing-vibrato, etc.). In uncritical, high-level applications, the VCAs can also be used for audio signals (e.g. regulate VCO outputs).@+@+For gain control, two control voltage inputs are available. The control voltages applied to them are summed.@+@+, Linear voltage controlled amplifier, Width: 4 HP, Depth: 35 mm, Power requirements: +20 mA (+12 V) / -10 mA (-12 V)
