There are also continuously variable input gain controls for matching input sensitivity, 3-band equalization, and extensive VU metering for easy, accurate level control. Drawing on Yamaha’s vast background in the sound reinforcement field, the RM804 is a remarkably compact, multifunction, high-performance mixer that is ideal for 4 or 8 track recording applications. In order to obtain the highest possible performance and make the most of the RM804’s extensive professional features, we urge that you read this owner’s manual thoroughly.
