Experience the latest blockbusters and your favorite movies like never before in your home theater with the sound quality and power only McIntosh can deliver.

Highlighted by our new eye-catching TripleView™ Power Output Meter that independently indicates the real time power reading of the three front channels.

Delivers 250 Watts per channel when using just the three front channels. When using all 7 channels, each receive a healthy 200 Watts per channel.

Dynamic Power Manager® (DPM) technology delivers the full 200 or 250 Watts to either 4 or 8 Ohm speakers.

Compared to previous model, dynamic headroom - a key feature in a home theater amplifier - increased 94% from 1.7dB to 3.3dB.

 

Overview

Features five McIntosh Monogrammed Heatsinks™ that efficiently and silently cool the amplifier; as a result, noisy cooling fans are not needed. A quiet, specially wound toroidal isolation power transformer also helps keep noise to a minimum.

Has multiple uses: it can power a 7-channel home theater; it can be paired with either our MI128 or MI254 digital amplifiers in theaters that have more than 7-channels; or it can be used in 5-channel theaters with 2 of its channels available to power a second audio zone.

Includes Power Guard®, Sentry Monitor™, Power Control, our eco-friendly power management system, and direct LED lighting of the front panel.
