Broca

A Simple and Open Source 4 Channels Audio Mixer

This module is inspired by the Doepfer A-138n and uses some parts of the schematics of the Befaco STMix.

While inspired by those modules, it is better at handling audio signals because of the high quality capacitors it uses on the audio path and the better overall noise filtering.

Features
- 4 mono channels with independent volume control
- 1 output
- 1 inverted output
- High quality audio capacitors on the signal path (Nichicon MUSE ES Bipolar)
- Low ESR filtering capacitors on the power path

This module is designed to mix audio signals with very low noise and distorsion.

Mixing CV signals is also possible but low frequency signals can get distorted in unexpected ways, try it and see if it works for you :)

This module is Open Source
All details and schematics are available on the Github repository
