The module consists of two identical voltage controlled amplifiers (VCA). Each VCA has a controller for manual setting of the basic gain (Initial Gain) and a control voltage input CV with attenuator. The control characteristic of each of the two VCAs can be chosen between linear and exponential. All inputs and outputs are DC coupled. Therefore, the module can also be used to process control signals (eg to get a controllable amplitude of LFOs or envelopes).
The signal input has no attenuator, but the module can process signals up to approx. 16Vss (ie from approx. -8V to approx. + 8V) without distortion.
