Patch-configurable 6 channel mixer/attenuverter
Module consists of 6 attenuverters, connected in a series. Connecting a patch cable to any output breaks a chain in that point. That way you can create separate mixer segments, connecting signals for mixing on the left, from top to bottom, and then collecting result from the output of the last channel.
Can be used for any signal: audio, LFO and constant voltages.
