• Dual Log/Lin Voltage Controlled Amplifier
   ELECTRONIC MUSIC > Synthesizer Modules > GMS-712EU  
    The GMS-712EU Dual Log/Lin Voltage Controlled Amplifier contains two high quality VCA devices in a 6HP 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 or more. The control curve can be set for a linear or logarithmic response to the input control voltage.    
    The module contains two separate 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 in the associated amplifier channel.

The control voltage response curve is determined by a panel toggle switch. When the switch is down, the response curve has a linear action. When the switch is up, the response curve has a logarithmic action. This response is similar to the logarithmic taper on a normal volume control.
