Stereo VCA with Stereo Audio Thru

SVCA is a High Performance Stereo Voltage Controlled Amplifier with plenty of gain to boost signals.

If you insert an audio source into the jacks L IN and R IN it will be directly routed to the THRU jacks where you may use your original signal for further stereo processing.

The signal is also directly routed to the Stereo VCA. Here you can control the volume or amplitude of the audio either manually or via control voltage using the CV jack.

Turning the CV Potentiometer will attenuate the incoming CV signal. The Offset Potentiometer will offset the level where the amplifier will start to take effect.

SVCA is great to split your stereo signal for further audio processing and simultaniously change the amplification via CV to create complex harmonics from a single stereo source.
