A-135-5 Polyphonic Mixer

Module A-135-5 is a combination of a voltage controlled polyphonic mixer and a polyphonic suboctave generator. It is made of 12 voltage controlled amplifiers (VCAs) which are arranged in form of a 4x3 matrix. Herewith up to three four-voice polyphonic signals (e.g. the outputs of three polyphonic VCOs A-111-4) can be mixed. The level of each of the three polyphonic channels (A, B, C) with four voices each can be controlled manually or by means of an external control voltage with associated attenuators.
In addition the module features four frequency dividers which derive the suboctaves from the four input signals of channel A.  The suboctave signals are wired to the switching contacts of the sockets of channel B.
