Anthem MRX 1140 8K 15.2 Channel AV Receiver

The Anthem MRX 1140 8K is the flagship of Anthem's MRX range: a 15.2 channel AV receiver with eleven built-in amplifier channels, designed for large Dolby Atmos home cinemas. Straight out of the box it can drive a 7.2.4 or 9.2.2 system, with the processing to expand all the way to 9.2.6.

A toroidal power supply, two independent subwoofer outputs, seven 8K HDMI 2.1 inputs with eARC and a Zone 2 output, Anthem's latest ARC Genesis room correction and built-in streaming make it a complete command centre for a serious home cinema.

For dedicated cinema rooms, media rooms and custom installations, the MRX 1140 8K delivers outstanding performance without the need for separate processors and power amplifiers.

Eleven Channels of Anthem Power

Eleven high-performance amplifier channels let you run a full 7.2.4 Dolby Atmos system without a single external amplifier. The main five channels deliver a conservative 140W each into 8 ohms (170W into 6 ohms), keeping demanding home cinema speakers controlled even at reference volumes.

Two independent subwoofer outputs let you integrate a pair of subwoofers for smoother, more even bass, and 15.2 channel pre-amp outputs give you room to expand.

8K HDMI 2.1 for Movies & Gaming

Seven dedicated 8K HDMI inputs and two main outputs, including eARC, plus a dedicated Zone 2 HDMI output, pass through 8K/60Hz and 4K/120Hz video with HDCP 2.3, so your 4K Blu-ray player, streaming box and games console all connect in one place.

HDR10, HDR10+, Dolby Vision and HLG are all supported, along with VRR, ALLM and QFT for smooth, responsive gaming. eARC also lets your TV send high-quality audio, including Dolby Atmos, from its built-in apps back to the receiver.

Immersive Dolby Atmos up to 9.2.6

The MRX 1140 8K decodes Dolby Atmos, DTS:X and IMAX Enhanced soundtracks with 15.2 channel processing. Drive a 7.2.4 layout with four ceiling speakers straight out of the box, or add external amplification for a full 9.2.6 system.

Premium 32-bit/768kHz DACs ensure everything from film soundtracks to hi-res music is reproduced with detail, dynamics and clarity.

ARC Genesis Room Correction

Your room has a huge effect on how your speakers sound. Anthem's award-winning ARC Genesis uses a precision calibration microphone and advanced algorithms to measure every speaker and subwoofer, then corrects frequency response, level and phase to fix room problems rather than mask them.

The latest version features a redesigned, more accurate microphone, and you can store up to four profiles for different listening setups.

Built-In Wireless Streaming

Stream music straight to the MRX 1140 8K with Apple AirPlay 2, Google Cast, Spotify Connect and Bluetooth, with no extra streamer needed.

Hi-res FLAC, ALAC, WAV and DSD files are supported, and AirPlay 2 lets you group the receiver with other AirPlay speakers around your home for multi-room listening.

Toroidal Power & Flexible Amplification

A robust toroidal transformer, chosen for its exceptional efficiency and ultra-low noise, forms the foundation of the MRX 1140 8K's clean, effortless power delivery.

Unused amplifier channels can be reassigned to bi-amp demanding front speakers or drive a second zone, and a dedicated Zone 2 HDMI output lets you enjoy a different source in another room.

Simple Setup with the Web Interface

Anthem's web interface lets you configure every setting from a browser on your phone, tablet or laptop, from speaker setup and levels to inputs and listening modes.

Up to 30 virtual inputs let you pair any video source with any audio input and speaker profile, so your system works exactly the way you want.

Ready for Custom Installation

With IP and RS-232 control, the MRX 1140 8K integrates seamlessly with Control4, Savant, Crestron, URC, RTI and ELAN control systems, making it a dependable choice for custom installers.

An optional rackmount kit (sold separately) lets you fit it into a standard 19-inch AV rack in 4U of space.

Anthem Remote App

Control volume, inputs, listening modes and ARC from your phone with the free Anthem Remote app, or use the included remote control.

The 6-inch colour front display keeps volume and input information clear at a glance.
