VOLTAGE CONTROLLED AMPLIFIER
The VCA is an amplifier whose gain can be changed with a modulation signal, typically
an envelope.
There are four choices available on the rotary switch.
EG1
EG1 CV is used to control the VCA level.
EG2
EG2 CV is used to control the VCA level.
GATE
MIDI Gate - an on/off (organ like) voltage is used to control the VCA level.
THRU
The VCA is left ‘open’ / on. It stays at full level.
CV Level control and socket
An external CV can be used to control the VCA level.
