Instruo vincâ

Dual VCA with four-quadrant multiplication and series/parallel routing

4 HP Eurorack module

vincâ is a dual voltage controlled amplifier from Instruo with both parallel and series routing capabilities. Each of its two VCA channels has a different architecture: Channel 1 is a four-quadrant multiplier with input bias and attenuverter controls, while Channel 2 features a fader-style amplitude control with variable linear-to-exponential response curve shaping. The Mode switch selects between parallel operation (both channels sum to Output 2) and series cascading (Channel 1 feeds into Channel 2). Multiple vincâ modules can be chained together via rear panel jacks for distributed mixing throughout a system.

Features

  • Two independent VCA channels with different architectures
  • Channel 1: four-quadrant multiplier for ring modulation
  • Channel 2: amplitude VCA with fader control
  • Input Bias adds positive or negative DC offset
  • Input Attenuverter scales and inverts signals
  • Variable response curve: linear to exponential
  • Parallel mode sums both channels to Output 2
  • Series mode cascades Channel 1 into Channel 2
  • Normalled +5V reference on Input 1B and CV Input
  • Infinitely chainable via rear panel jacks
  • DC coupled inputs accept audio and CV
  • Unity gain at two-thirds fader position
