McIntosh MI347 7-Channel Digital Power Amplifier
Country of Origin: Usa
The MI347 7-Channel Digital Powerr Amplifier is a dedicated home theater amplifier that packs a hefty punch with an immersive sonic experience that provides a heart-stopping, edge-of-your-seat audio experience in the comfort of your home theater. It uses functionally sophisticated closed loop digital switching amplifiers that are paired with extremely robust power supplies that produce audio performance levels rarely heard in home theaters.
Meant to be heard more than seen – such as being set up in an out-of-sight A/V equipment rack, the MI347 has a simplified and understated exterior. But rest assured that the internal circuitry and components have received the full attention of the McIntosh engineers to make you feel like you are part of your favorite movies. With its rack-friendly 3U height, it can effortlessly be installed in your A/V rack via the included rack mounting brackets (the mounting brackets are removable for non-rack installations). But the MI347 is not limited to just rack installations, as it can also be placed out in the open for all to indulge in.

Benefits of McIntosh MI347 7-Channel Digital Power Amplifier:
Edge-Of-Your-Seat Audio Experience
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.
Highly efficient Class D amplifier
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 the standard 5-way speaker binding posts.
Can be used with any McIntosh home theater A/V Processor
The MI347 can be used with any McIntosh home theater A/V Processor like the 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 the McIntosh MI254 4-Channel Digital Amplifier or MI128 8-Channel Digital Amplifier (both rack mountable) to deliver McIntosh power to all your home theater speakers. 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.
