Exclusive McIntosh Power Assurance System:
A collection of technologies that enhance performance and reliability while protecting the amplifier and loudspeakers.

Power Guard®:
A waveform comparison circuit continuously monitors both input and output signals. Power Guard dynamically adjusts the input level to avoid clipping while preventing harsh sounding distortion.

Sentry Monitor:
Fuse-less short-circuit protection circuit disengages the output stage before current exceeds safe operating level; resets automatically.

Output Autoformer:
Unique McIntosh technology delivers the full rated amplifier output with the least possible distortion into loudspeaker impedances of 2, 4, or 8 Ohms; you get all the power you paid for and the freedom to choose any loudspeaker.

Swift, accurate response reveals program peaks to make staying within the power limits of your loudspeakers is easy.
