McIntosh MI347 7-Channel Digital Amplifier

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 or ceiling 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 along with our standard 5-way speaker binding posts.

The MI347 can be used with any McIntosh home theater A/V Processor like our MX123, MX180 or rack mountable MX100. If you've got more than 7 audio channels in your home theater, such as with Dolby® Atmos or DTS:X™, you can add our MI254 4-Channel Digital Amplifier or MI128 8-Channel Digital Amplifier (both rack mountable) to deliver McIntosh power to all your home theater speakers.

Other features included with the MI347:

• Power Guard® signal overload technology that prevents overdriving and damaging your speakers
• Sentry Monitor™ short-circuit protection circuit that disengages the output stage should current ever approach unsafe operating levels and then resets automatically when operating conditions return to normal
• 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 your home theater processor

The MI347 includes many McIntosh design cues including a black glass front panel, an illuminated McIntosh logo, and a familiar form factor highlighted by silver trim. Contact your local dealer to learn more.
