The Quad VCA is designed as a utility module for providing fourItalic text basic VCA's to be grabbed for a patch.
Each of the four identical VCA's include:
Channel input: The VCA's are DC coupled to allow for signal processing of CV or audio signals.
CV input: The amplifier stage responds to a 0 to 5V control voltage.
5V for full output. 0V for fully attenuated.
All of the CV inputs are cascaded.
The CV applied to channel 1 will control all four VCA's. Inserting a CV into another CV input will interrupt the cascade and apply the new CV to the selected and subsequent channels.
Level control: Allows for adjusting the gain stage of the channel from 0 to unity gain. On-board trimmer potentiometers allows for the user to adjust the maximum output gain for each channel up to just below the power supply limits providing up to a 2.5 gain amplification of the input signal.
Channel output: Output jack for the channel.
