A-132-8 is an octal VCA and primarily planned for polyphonic applications. The module contains four VCA pairs. The amplification range for each VCA is 0 ... 1. 0V CV corresponds to amplification 0 (full suppression), +10V CV to amplification 1. 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). All VCAs are DC coupled and can be used in special applications also for the processing of control voltages.
