Anthem MRX 1140: Modern flagship AV receiver

Anthem MRX-1140 is the most modern flagship AV receiver of the Canadian company, already belonging to the fourth generation of the MRX series. It is also one of the rare models that offers, in addition to Dolby Atmos/DTS:X 3D decoders, a built-in 11-channel power amplifier. Accordingly, the speaker systems connected to it can be configured up to 7.2.4 (seven main layer speakers, two subwoofer modules, four vertical effects speakers). The amplifier power is 140 watts into an 8 ohm load.

In addition to 11-channel amplification, the Anthem MRX-1140 receiver is equipped with a unique ARC (Anthem Room Correction) electronic sound correction system, which many audio experts consider one of the most advanced in the world. ARC Genesis is the latest software that works with many ARC-enabled Anthem or Paradigm products. New features include Mac and Windows support; new target curve settings including deep bass and treble; improved algorithms and much more.

ARC Genesis is backwards compatible with many Anthem and Paradigm products that support ARC or PBK. To see the full list, visit This third generation of Anthem Room Correction software represents a significant step forward in room correction with the most comprehensive feature set yet. ARC Genesis transforms the sound characteristics of compatible speakers or electronics while maintaining the unique character of any room. Proprietary Digital Signal Processing (DSP) software works in tandem with a calibrated microphone (included with many ARC and PBK-enabled products) to deliver dramatic improvements to the sound you hear.

The MRX 540, 740 and 1140 AV receivers are a great way to bring premium audio to any home theater or media room. Ultra HD signals are transmitted unchanged up to 18.2 Gbps with support for Dolby Vision, HDR and Hybrid Log Gamma. All models feature HDMI eARC 2.0b inputs, with future upgrades to HDMI 2.1 (8K) specifications.

All AVM/MRX components support Apple AirPlay and AirPlay 2, which allow the user to stream content as well as songs stored on local networks to any AirPlay-enabled device. AirPlay 2 adds support for multi-device playback, so you can hear your music anywhere in the home.


Anthem’s web user interface is now built into all MRX receivers and AVM processors. Using a phone, tablet or laptop, owners can easily access any feature or setting and make changes instantly. Turn your main or second zone on and off, adjust volume, change sound modes, or customize channel trim for perfect surround sound. The web interface can also be used to calibrate delays and speaker levels, and configure network/control settings. Source devices can be renamed, simplifying setup by eliminating unused inputs. Installers can import and export files to make remote management simple and convenient.


The powerful, rich sound of the receiver, both on dynamic movie soundtracks and on musical material, leaves no one indifferent. The developers have done a great job and deserve all respect – there is hardly a competing device on the market with a similar sound. The Dolby Atmos demo disc sounds amazing, all the effects are clear, and the movement and localization of the sound image is top notch. No matter which listening mode is selected – stereo or multi-channel – the result is always excellent. The very deep bass immediately attracts attention – this is one of the hallmarks of Anthem AV equipment.
