Both VCAs are identic: the signal input can be AC- or DC-copled witha switch which makes possible to use te module wither with slow CVs or with audio signals. The characteristic of the VCA, exponential or linear, is determined with another switch.
Each channel has a potemtiometer for manually setting the VCA's initial gain and two modulation inputs which are exipeed with polarizers (bi-polar attenualtors) for scaling and inverting the modulation.
In combination with the normalizations of all left channel inputs to the right channel the polarizers are especially interesting as you can achieve voltage controlled pannings very easily: one channel is modulated in a positive manner and the other one inverted - the signal starts moving between the channels.
The VCAs outputs are summed at the Mix Out which turns the module into a voltage controlled two-input mixer.
Finally the module has a ring modulator. The input of the left VCA is used as the modulator input and the right channel's input as the carrier input.
