| A-133 is a special dual voltage controlled amplifier that enables both
positive and negative amplifications. 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 is about -2.5....0....+2.5 (other
amplification ranges for small additional charges, e.g. -1...+1 or
-5...+5). Amplification can be adjusted manually (Man control) and by
an external control voltage with attenuator (CV). The present
amplification is displayed with two LEDs: one for positive and one for
negative amplifications (not a signal display but amplification diplay,
similar to A-134).
Another module with polarizing function is the Polarizing Mixer A-138c.
