McIntosh MC303 3-Channel Solid State Amplifier
- 300 Watts x 3 Channels
- Designed for home theaters
- Tri-Amp capability
The McIntosh MC303 is our most powerful multi-channel amplifier to date, providing 300 Watts into each of 3 channels. It features our 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. For surround channels, combine the MC303 with our MC312 or MC152 amplifiers and fully immerse yourself in your movie collection. For music lovers, the MC303 can be used in tri-amping configurations on compatible speakers, such as our XRT1.1K or XRT2.1K.
The MC303 shares many notable McIntosh technologies that are found in our other home audio and home theater products, including Power Guard® that prevents over-driving of the amplifier and the resulting harsh sounding clipping that could damage your speakers. Sentry Monitor™ is our fuse-less short-circuit protection circuit that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal. Inputs for both balanced cables and unbalanced cables are available to provide flexibility in connecting to the rest of your system. A triple bank of blue watt meters provides instant recognition of power output (the meters may be switched off for theater use if they conflict with the television or movie screen).
Aesthetically, the MC303 is every bit as McIntosh as any of our products. A polished stainless steel chassis, classic black glass front panel, knobs and custom machined aluminum handles all come standard.
