Three Channels of High-Power Performance
The MC303 delivers 300 watts per channel into 2, 4, or 8-ohm loads, supplying ample headroom for demanding home theater front channels or for tri-amped speaker configurations.
Autoformer™ Technology for Consistent Output
McIntosh’s Autoformer™ ensures each channel produces its full rated power regardless of speaker impedance, maximizing performance and maintaining consistent sound quality across different speaker loads.
Advanced Protection Systems
Power Guard® continuously monitors incoming signals to prevent clipping and distortion, while Sentry Monitor™ provides fuse-less protection by shutting down the output stage if unsafe conditions arise, then automatically restoring operation when normal conditions return.
Iconic Blue Watt Meters
Three large watt meters provide real-time visual tracking of power output for each channel. The illumination can be switched off when used in a darkened home theater environment.
Flexible Connectivity
The amplifier offers both balanced and unbalanced inputs, making it easy to integrate with a wide range of preamps, processors, and home theater systems.
Signature McIntosh Build Quality
With its polished stainless steel chassis, black glass front panel, and machined aluminum handles, the MC303 embodies McIntosh’s renowned craftsmanship and long-term reliability.
