About the Anthem MRX 1140 8K

Anthem’s flagship receiver is an A/V masterpiece

Anthem’s top-of-the-line receiver just got an 8K upgrade — all 10 HDMI connections (7 in and 3 out) support 8K at 60Hz and 4K at 120Hz. The MRX 1140 8K doesn’t skimp on audio quality either — it offers exceptional signal processing, amplification, and room correction, along with an advanced digital to audio converter. It also has a fantastic web-based control system, allowing you to set up and control your system from your computer or smart device.

Enjoy theater-quality Atmos surround sound at home

The MRX 1140 8K is capable of driving up to 11 speakers at the same time. That means you can power an ultra-immersive 7.2.4-channel Dolby Atmos or DTS:X™ system, with up to four upward-firing or in-ceiling speakers for overhead effects.

Plenty of power for each channel

Five of the receiver’s channels feature a Class AB design and are rated at 140 watts per channel with two channels driven. They’re well-suited for high-performance stand-mount or floor-standing speakers.

The other six channels use Class D amplification and are rated at 60 watts per channel with two channels driven. That’s plenty of power for surround and overhead channels that reproduce less-demanding portions of a movie’s soundtrack.

A high-quality toroidal power supply helps ensure top-notch sound from each channel.
