A-132-8 Octal Poly VCA

Doepfer's octal VCA for polyphonic patches: four pairs of VCAs in series, one for the envelope and one for velocity, per-voice levels or modulation, with a sum output.

Key features

• Eight DC-coupled VCAs in four pairs, gain 0 to 1 for 0 to +10 V
• The first VCA of each pair (L) is linear, the second (X) linear or exponential by an internal jumper
• CV inputs 1L to 4L and 1X to 4X; GL and GX set a default gain normalled to them, to open unused VCAs or tune
• Four audio inputs and outputs, plus a sum output
• Made for polyphonic systems, such as the A-141-4 polyphonic ADSR
