Mst Unity Gain Mixer. The MST 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 also 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: Two 5:1 Unity Gain Mixers 5 inputs per channel Mixes both AC signals (audio) and DC signals (gates, triggers, CV) Channel A output normalled to first input of channel B Input signals are not boosted or cut Sum of inputs is the total output Polarity protected Specifications: Current draw: +12V: 9mA -12V: 9mA Module Depth: 22mm Width: 6HP Product Features Two 5:1 Unity Gain Mixers, 5 inputs per channel.
