Announcing the MI347 7-Channel Amplifier


Edge-Of-Your-Seat Audio Experience.

 McIntosh is proud to announce the new MI347 7-Channel Amplifier.

 The MI347 7-Channel Digital Amplifier is a dedicated home theater amplifier that delivers an immersive sonic experience that provides a heart-stopping, edge-of-your-seat audio experience. It uses highly sophisticated closed loop digital switching amplifiers that are paired with extremely robust power supplies that produce audio performance levels rarely heard in home theaters. While the MI347 has a simplified and understated exterior, the internal circuitry and components have received the full attention of the McIntosh engineers to make the viewer feel like they are part of the movie.

In a home theater, the most important audio channels or speakers are the front left, front right, and center channel speaker. These are where a majority of the dialogue and the loudest and most prominent special effects resonate from. As such, the MI347 will deliver 250 Watts at 8 Ohms or 300 Watts at 4 Ohms to each of these three speakers. The MI347's other four channels are meant to drive the still important but less power-hungry surround sound speakers. To each of these four channels, the MI347 will deliver a healthy 125 Watts at 8 Ohms or 200 Watts at 4 Ohms.

A highly efficient Class D amplifier, the MI347 does not require noisy cooling fans to maintain nominal operating temperature; it also features an abundance of cooling vents on the top and sides to further assist with heat dissipation. On the front panel, multi-color LED indicators display the status of each channel. On the back, both a balanced and unbalanced input is included for each channel.


The MI347 is ideally suited to be paired with the rack mountable McIntosh MX100 A/V Processor, but can also be used with McIntosh's MX123 and MX170 processors, or with virtually any home theater processor. If there's more than 7 audio channels in the home theater, such as with Dolby® Atmos or DTS:X™, McIntosh's MI254 4-Channel Digital Amplifier or MI128 8-Channel Digital Amplifier (both rack mountable) can be added to deliver McIntosh power to all the speakers.


Other features included with the MI347:

Power Guard® signal overload technology that prevents overdriving and damaging the speakers

Sentry Monitor™ short-circuit protection circuit that disengages the output stage should current ever approach unsafe operating levels

Power Control to automatically turn other connected McIntosh components on and off

Eco-friendly on/off signal sensing that turns the unit off if no input signal has been detected for a set amount of time and – perhaps more conveniently – automatically turns the MI347 on when it senses a signal from the home theater processor.
