Happy Nerding

6-channel attenuverting mixer/offset/scale/polarizer in 3 blocks of 2-channel attenuverting mixers using dual concentric pots. DC coupled for audio, CV, or both.584

Capabilities 4

Attenuverterattenuverter
Each of the 6 input channels has a bipolar attenuverter knob capable of scaling and inverting the input signal.584
Mixermixer
Three independent 2-channel mixer blocks that can be chained for 2-2-2, 4-2, or 6 mix configurations.584
Offsetoffset
With nothing plugged into an input, an offset is normalled to that channel, making each unpatched attenuverter knob a manual offset/bias voltage source.584
Polarizerpolarizer
Bipolar attenuverter knobs allow polarity inversion of input signals.584

Jacks 9 — 6 in / 3 out
