Anthem's flagship receiver is an A/V masterpiece
I've long admired Anthem for their high-performance A/V gear. I'm particularly impressed by the MRX 1140 — the company's flagship home theater receiver.

This sleek-looking receiver offers exceptional signal processing, amplification, and room correction. It also has the best web-based control system I've seen, allowing you to set up and control your system from your computer or smart device.

Anthem MRX 1140 11.2-channel home theater receiver
The MRX 1140's large front-panel display gives you easy-to-read status updates at a glance.

Enjoy theater-quality Atmos surround sound at home
The MRX 1140 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 MRX 1140's channels are rated at 140 watts (Class AB amplification), and are well-suited for high-performance stand-mount or floor-standing speakers.

The other six channels are rated at 60 watts (Class D), which is 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.

Intuitive web-based controls
One of the features that makes Anthem's receivers stand out from the crowd is their user-friendly control interface. Access it from a web browser on your computer or smart device, and easily turn zones on and off, adjust settings, switch up speaker configurations, and more.

Advanced room calibration with ARC Genesis
The MRX 1140 includes the company's own highly regarded ARC (Anthem Room Correction) Genesis software — one of the industry's best room-correction platforms.

ARC Genesis measures the acoustics of your room with the included microphone, and then fine-tunes the output of your system to best match the unique sonic characteristics of your space. The resulting sound is clear, smooth, and ultra-detailed, with tight bass and impactful dynamics.

Note: You'll need to install the free ARC Genesis software on your Mac® or PC prior to calibration.
