  GMS-712MU Dual VCA
    The GMS-712MU Dual Voltage Controlled Amplifier contains two high quality VCA devices in a 1MU panel. Each amplifier can be used with an external control input to produce a change in amplifer gain from infinite attenuation to a gain factor of 1 and beyond. The control curve can be set for a linear or logarithmic response to the input control voltage. The control voltage inputs are equipped with reversible attenuators.    
    The module contains two seperate high quality voltage controlled amplifier channels. Each channel has an associated control voltage input that passes through a reversible attenuator. The attenuator allows the control voltage to be prescaled from zero up to twice the applied level. When the attenuator control is positioned to the left of 0, a greater negative voltage on the control input will produce higher gain values approaching a gain of 1 at 5 Volts in the associated amplifier channel. Higher voltages produce gain beyond X1 to as much as X2.5.

The control voltage response curve is determined by a toggle switch. When in the LIN position the response curve has a linear action. When in the LOG position the response curve has a logarithmic action. This response is similar to the logarithmic taper on a normal volume control.
