McIntosh MHT300

The McIntosh MHT300 Home Theater Receiver (or AV Receiver or AVR) is an uncompromising 7.2 (or 5.2.2) channel home theater powerhouse sure to heighten your emotional connection to what you are watching.

With support for breathtaking 8K/60Hz and 4K/120Hz video and leading home theater surround sound audio formats Dolby® Atmos and DTS:X, plus delivering 120 – 150 Watts of legendary McIntosh power to your home theater speakers, the MHT300 will make your home theater dreams come true.

Full Power to All Speakers All the Time

Don’t be fooled by high watts per channel specs listed by many other AV receivers on the market as many times the fine print will show that those power ratings only apply to just two channels driven.

That may be fine for a stereo setup, but a home theater has a lot more than just two channels to drive.

With the MHT300, the power ratings are for all seven channels being driven.

That means every 4 Ohm speaker will receive 150 Watts and every 8 Ohm speaker will receive 120 Watts of heart pounding McIntosh power to bring all your favorite movies and video content to life.

Every explosion, every car chase, every high-speed flyby of a fighter jet or spaceship, every roar of the crowd after a game winning score will be faithfully reproduced by 120 – 150 Watts on every one of your speakers.

With the MHT300, you’ll no longer have to wonder if each speaker is getting the full power listed on the box.

Can Expand with Your Needs

AV amp

The MHT300 can also grow with your theater as its individual amplifier modules can be configured in many ways to suit your specific speaker configuration.

If someday your home cinema expands beyond seven channels, additional external amplifiers can be connected to the MHT300 to power them via the Height 1 and Height 2 audio outputs.

An external amplifier, such as the McIntosh MI254 4-Channel Amplifier, would be connected to these outputs to drive these additional speakers.

This would effectively turn the MHT300 into a 7.2.4 channel AVR.

Even if you do not add more speakers to your home cinema, more power could be added.

For example, if you decide you want more power for your front left and right speakers, you can add an external stereo amplifier to your system (such as the McIntosh MI502 amplifier) and connect it to the MHT300 by simply removing the jumper from the selected channel(s), then connecting the output on the MHT300 to the input on the stereo amplifier.

Or you could connect a higher power mono amplifier to drive the center channel speaker.

In these cases, the selected channel(s) would be driven by the more powerful external amplifier.
