Description
Doepfer's earlier two voltage-controlled polarizers in 8 HP: each amplifies a signal by about -2.5 to +2.5, so it can also invert it. No longer made; its replacement is the A-133-2.
Key features
- Two channels, each with a manual gain control (Man.) from inverted through zero to positive
- A CV input per channel with its own attenuator, added to the manual setting
- Signal input and output per channel, for control voltages (envelopes, LFOs) or audio (waveshaping, ring modulation)
- Two LEDs per channel show the present gain, negative or positive (not the signal)
