AS3360-based Dual Linear VCA

This is a Dual Linear Low Noise VCA module, based on the AS3360.

Both VCAs can be controlled by a CV entry, modulated by control knob.

VCA1 also has an initial gain control (B1), that offsets the CV input by a constant value. This allows VCA1 to be left always open, with the initial gain controlling the amplification.

If both input jacks are used (IN1, IN2), the two VCAs will operate independently. The output of VCA1 will go to OUT1, the output of VCA2 will go to OUT2.

If there's no jack in IN2, the two VCAs will be cascaded, and the output of VCA1 will go both to OUT1 and as an input to VCA2.
This allows this module to be used to process both the MIDI Velocity and the envelope of an audio signal.


Inputs:

  • IN1: Input Signal for VCA1.
  • CV1: Control Voltage for VCA1's amplification.
  • IN2: Input Signal for VCA2. If no IN2 is present, the input of VCA2 will be the output of VCA1.
  • CV2: Control Voltage for VCA2's amplification.

Outputs:

  • OUT1: Output of VCA1
  • OUT2: Output of VCA2

Controls:

  • M1: Attenuator for CV1
  • B1: Initial gain of VCA1
  • M2: Attuenator for CV2
