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.


  • 7.2 channel AVR (expandable to 7.2.4)
  • 150 Watts per channel into 4 Ohms/120 Watts per channel into 8 Ohms (ALL 7 channels driven)
  • 4 HDMI inputs & 1 HDMI output: 8K/60Hz & 4K/120Hz; HDCP 2.3; 40Gbps; Rec. 2020; 4:4:4 Color; eARC/ARC

Full Power to All Speakers All the Time

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

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.

State-of-the-Art Room Correction

Advanced room adjustment and correction is provided via Dirac Live® Room Correction. Dirac Live is an advanced room acoustic solution that enables users to optimize their sound systems and reduce unwanted effects introduced by the room. Utilizing purpose-built audio algorithms, Dirac Live provides world-class room correction with time domain correction by means of patented mixed-phase filter technology – something that all other solutions are missing. Dirac Live is nevertheless easy to use, with an intuitive user interface and step-by-step guidance that allows for quick setup and robust personalization. Dirac Live is trusted by numerous hi-fi and home theater manufacturers, from household names to the most coveted designer brands. Their room correction solution has brought unparalleled fidelity to hundreds of thousands of delighted users worldwide, in listening situations as diverse as bedroom stereo setups, professional mixing studios, and some of the world's most exclusive home theaters.


The MHT300 has 4 HDMI inputs and 1 HDMI output. Each HDMI port is HDCP 2.3 compliant and support 8K/60Hz and 4K/120Hz. All ports have 40Gbps of bandwidth and are compatible with High Dynamic Range (HDR) formats Dolby Vision™, HDR10 and HLG; 4:4:4 color spacing; Rec. 2020; and 3D video pass-through.

Audio Return Channel (eARC)

The HDMI output features enhanced Audio Return Channel (eARC) functionality. Audio Return Channel allows a compatible TV to send audio data to the audio video processor over the HDMI cable, eliminating the need for separate audio cables. eARC offers improved bandwidth so higher resolution audio formats such as DTS-HD Master Audio™, DTS:X®, Dolby TrueHD, and Dolby Atmos can be sent through the HDMI cable, allowing the MHT300 to deliver the best possible sound quality.2 Two coax and 2 optical digital audio inputs are included to connect additional audio devices, while 2 subwoofer outputs will let you have as much bone-rattling bass as you want in your theater.

Digital-to-Analog Converters (DACs)

Seven premium 32-bit Digital-to-Analog Converters (DACs) provide audiophile-grade processing. Bass and treble tone controls are included to help fine-tune the audio to your personal preferences. Sturdy 5-way speaker binding posts will firmly connect your speaker cables so you do not have to worry about them coming loose.

Easy Setup

Setup and configuration are easily performed via computer interface. To save time, your installer can pre-configure your unit before bringing it to your home and then simply load the configuration file at installation. The MHT300 can be operated via the included remote control, or your integrator can easily incorporate it into your home automation system via RS232 control protocol.


The MHT300 AVR includes many McIntosh design cues including a black glass front panel, an illuminated McIntosh logo, rotary control knobs, and a familiar form factor highlighted by silver trim. A work of art that can be placed front and center in your home theater for all to enjoy, the MHT300 can also be placed in hidden or out-of-the-way A/V equipment rack thanks to the included rack mounting brackets and its 3U rack size.
