MC303 3-Channel Amplifier

The McIntosh MC303 is McIntosh's most powerful multi-channel amplifier to date, providing 300 Watts into each of 3 channels. It features their renowned Autoformer which allows its full 300 Watts of power to be delivered into 2, 4 or 8 Ohm speakers with the lowest noise and distortion performance possible.

The MC303 was designed with the intent to drive a home theater’s front left, front right and center channels. As most of a movie’s soundtrack is delivered by these three channels, the powerful MC303 provides all the power needed for an amazing in-home theater experience. If building a five channel theater, combine the MC303 with the mono block MC611, 1.25K, Stereo MC452, MC312 and for high dynamic and resolution theaters.  Alternatively the MC303 can be used for the front three channels with a McIntosh multi-channel amplifier such as the MC255 to drive the surround and rear channels.
