Yamaha PM-170 is a six-channel input, stereo output mixer that can be used alone or as a submixer with more sophisticated models. It has a top electronic performance, with flat frequency response, low distortion, and inaudible noise and crosstalk. The PM-170 is mechanically solid and rugged enough for the road, but also ideal for permanent installation thanks to the standard 19” rack mounting. All solid state circuitry increases reliability and portability. The PM-170 has smooth rotary controls that offer smooth performance and give the user the mixing freedom and control they need.
