The Yamaha MX-55 is a power amplifier designed for both 2-channel stereo and 4-channel surround sound operation. It features selectable channel modes, speaker level controls, and an unswitched AC outlet for powering other components. The unit includes a speaker protection circuit that mutes output for a few seconds after power-on to prevent damage to speakers.
