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
