MA7000 Integrated Amplifier
Designed to deliver a continuous 250 watts per channel, the MA7000 Integrated Amplifier is the most powerful integrated amplifier McIntosh has ever offered. The MA7000 leads an already impressive array of McIntosh integrated amplifiers delivering uncompromised performance in a convenient, single-box solution. The MA7000 employs the famous McIntosh Autoformer. Designed and manufactured exclusively by McIntosh, the Autoformer helps the MA7000 deliver optimum performance with any loudspeaker. Whether your speakers are 2, 4, or 8 ohms the McIntosh Autoformer ensures that you will always get all of the power that you have paid for.
MA7000 Integrated 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.
