Two 5 in by 4 out mixers with provision for setting the amount of signal coupled from any input to any output. Commoned outputs provide 10 in by 4 out capability. Switches are provided for monitoring input signals through the Model 226 Quad Monitor Interface. 

The 205 Matrix Mixer is particularly useful for quadraphonic mixdown and distribution. Complex dynamic control of timbre can be achieved by inputting multiple oscillator or filter signals (additive or subtractive synthesis) and gating the outputs with a model 292 Lopass Gate.
