Blockbuster Power.

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.
