Multifunction Utility Mixing Module

• 4 Channel Mixer
• 4 Independent Attenuators
• 2 Attenuators and a 2 Channel Mixer
• 1 Attenuator and a 3 Channel Mixer

A flexible, low-noise four channel mixer and/or attenuator for audio and cv that can be used in several ways. Three of the four channels have an output that removes the channel from the mixer circuit and allows it to become a standalone attenuator.

The pots are wired with a logarithmic volume curve that is tuned for use with audio but it will work with CV as well.

Patching the output of channel 1, 2, or 3 will remove it from the mixer circuit. Channel 4 can not be removed from the mixer circuit, however if channel 1, 2, and 3 are all being used as attenuators, channel 4 is the only input remaining in the mixer allowing it to be used as a buffered attenuator.
