The kit version of the 1U Unity Gain Mixer. A unity gain mixer adds input signals together and combines them for a summed output.  For example, if you put in a 1V source and a 3V source, the output will be 4V.  It's mainly used for CV, but it can be used to combine audio signals together. 

 

A unity gain mixer is handy in several ways:

• Combining gates and triggers. Plug a few sequencer steps into the unity gain inputs, then run the output to a drum synth, VCA, envelope, etc.
• Re-shaping two CV sources with a single envelope
• Combining different wave shapes or LFOs to make crazy sounds.
• Controlling the CV of one source with the CV of another source. Just plug the CV out of a sequencer into and an expression pedal/touchable CV out into the unity gain inputs.

 

Features:

• 2 channels, 4 inputs per channel
• Mixes both AC signals (audio) and DC signals (gates, triggers, CV)
• Input signals are not boosted or cut
• Sum of inputs is the total output
• Channel A is not normalled to Channel B
• Polarity protected
