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.\u003c\/p\u003e\u003c\/section\u003e\n\u003cfigure class=\"mc-img-block\"\u003e\u003cimg src=\"https:\/\/www.mcintoshlabs.com\/-\/media\/images\/mcintoshlabs\/products\/productimages\/mi347\/mi347-angle-background.jpg?rev=55d64ad626c54a8f9edce65193290045\u0026amp;revision=55d64ad6-26c5-4a8f-9edc-e65193290045\" alt=\"McIntosh MI347 Amplifier\" loading=\"lazy\"\u003e\u003c\/figure\u003e\n\u003cfigure class=\"mc-img-block\"\u003e\u003cimg src=\"https:\/\/www.mcintoshlabs.com\/-\/media\/images\/mcintoshlabs\/products\/productimages\/mi347\/mi347-mounting-ear.jpg?rev=560aa859fae2490cabfef9b7dd3ad489\u0026amp;revision=560aa859-fae2-490c-abfe-f9b7dd3ad489\" alt=\"McIntosh MI347 Amplifier\" loading=\"lazy\"\u003e\u003c\/figure\u003e\n\u003csection id=\"section-1\" class=\"mc-section\"\u003e\u003cp\u003eMeant to be heard more than seen – such as being installed 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 easily 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 see and enjoy.\u003c\/p\u003e\u003c\/section\u003e\n\u003csection id=\"section-2\" class=\"mc-section\"\u003e\u003cp\u003eIn a home theater, the most important audio channels or speakersare 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.\u003c\/p\u003e\u003c\/section\u003e\n\u003cfigure class=\"mc-img-block\"\u003e\u003cimg src=\"https:\/\/www.mcintoshlabs.com\/-\/media\/images\/mcintoshlabs\/products\/productimages\/mx100\/mx100-mi347-system-lifestyle.jpg?rev=f257c8d80fb342feba5f4ca3e7ad8ce9\u0026amp;revision=f257c8d8-0fb3-42fe-ba5f-4ca3e7ad8ce9\" alt=\"McIntosh home theater system with MX100 A\/V Processor, MI347 Amplifier, MPV901 Audio Video Player, LCR80 Center Channel Speaker, XR100 Floor Standing Speakers\" loading=\"lazy\"\u003e\u003c\/figure\u003e\n\u003csection id=\"section-3\" class=\"mc-section\"\u003e\u003cp\u003eA highly efficient Class D amplifier, the MI347 does not require noisy cooling fans to maintain nominal operating temperature; it also features an abundanceof cooling vents on the top and sides to further assist with heat dissipation.
