The most powerful single chassis McIntosh amplifier, the MC1.2KW produces a massive 1,200 watts. The MC1.2KW features the extraordinary McIntosh Quad Balanced Circuit. Each amplifier consists of two balanced amplifier circuits, the outputs of which are combined in the unique, hand-crafted McIntosh Output Autoformer. The result? Totally balanced operation from input to speaker output that cancels virtually all distortion.

The MC1.2KW can be used with all loudspeaker types and features output connections that are optimized for 2, 4, and 8-Ohms for low distortion performance and maximum power transfer. With features such as DC failure protection and remote power control, the MC1.2KW is an ideal marriage of power and performance.


 

MC1.2KW Power Amplifier Features

 

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.

WATTMETER

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