Vertmix

RYO

3-channel bipolar mixer/attenuator with 5V offset (currently out of production)

Vertmix was designed as a handy CV mixer and processor with buffered inputs but its low-noise circuit means it will also work great with audio.

A 5V offset is normaled to the input of the first channel, giving it a maximum of 5V out turned full clockwise/right or minimum of -5V turned fully counter-clockwise/left. Please note that this offset will affect the mixing if the channel hasn't been patched on its input or output.

It works as 3 channel bipolar mixer,
1 bipolar attenuator + 2 channel bipolar mixer
or 3 bipolar attenuators.

The buffered inputs offer very large resistorless jFET impedance and is unaffected by output impedance (isolation/protection resistors) on the modules going in to the mixer. The inputs without offset voltage is grounded if no patch cable are inserted. If a patch cable is inserted in an input but loose at the other end, the input will be floating (this is modifiable by a resistor between input pin and ground on the input jacks, input impedance will then be equal to this resistors value).
The outputs have 1kohm impedance.
