Audio and Control Voltage Signal Router
The Pittsburgh Modular M3 is a unique signal routing module with 3 distinct sections able to perform several different functions at once. Signal splitting, mixing, and buffering are combined to create a module that is both compact and incredibly useful.
The top section labeled MULT, is a standard 4 jack passive multiple used to create 3 copies of the original signal. One input becomes up to 3 identical outputs.
The bottom 2 sections, MIX1 and MIX2, both function the same way. Two input and 2 outputs allow each section to be used as a 2 channel unity gain mixer, signal buffer, and buffered multiple.
