Doepfer - A-132-8: Octal Poly VCA

Manufacturer Description: A-132-8 is an octal VCA and primarily planned for polyphonic applications. The module contains four VCA pairs. Each pair includes two daisy-chained VCAs. One VCA has a linear control scale, for the second VCA linear or exponential control scale can be chosen by means of jumpers. We decided to provide two VCAs for each voice because usually one VCA is required for loudness envelope and a second one for velocity (or other functions like individual voltage-controlled loudness of each voice, amplitude modulation and so on). These controls and in/outputs are available: Default Gain 1 (GL)Default Gain 2 (GX)CV Input VCA 1CV Input VCA 2Audio InputAudio OutputIn addition an Audio Sum Output is also available.The module features two Default Gain controls (GL, GX), that enable the opening of the first VCAs (L) and/or second VCAs (X). For this the controls GL and GX generate two internal control voltages 0...+10V which are connected to the switching contacts of the socke
