The A-133 is a special dual voltage controlled amplifier that enables both positive and negative amplification. Negative amplification means in this context that the signal is inverted.
The main application of the module is the processing of control voltages, e.g. ADSR or LFO. The amplification range will be -5....0....+5.
Amplification can be adjusted manually (Man control) or by an external control voltage. The amplification state is displayed with two LEDs: one for positive and one for negative amplification.
