A-142-3

Envelope Controlled VCA

Module A-142-3 is the combination of a simple AD/AR envelope generator and a VCA behind a front panel with 4HP only.

The type of envelope can be selected by means of a toggle switch between A/D (Attack-Decay) and A/R (Attack/Release). Another toggle switch is used to choose envelope or (free running) LFO mode. The envelope output controls a linear VCA.

These controls and in/outputs are available:

• Attack control
• Decay/Release control
• AD/off/AR switch
• Envelope/LFO switch
• LED (envelope display)
• Gate Input
• Manual gate (momentary switch)
• Envelope Output
• VCA CV Input (normalled to Envelope Output)
• Audio Input with Level control
• Audio Output (the outputs of several A-142-3 can be internally mixed together)
