Anthem MRX 1140 8K

Surround Sound Receiver

The definitive home theatre command center.

With 15.2 pre-amp and 11 amp channels, 8K HDMI 2.1, and the unrivalled precision of ARC Genesis, it delivers a sonic and visual experience of absolute authority and fidelity.

The Absolute Authority in Home Theatre

The Anthem MRX 1140 8K is not just an A/V receiver; it is the culmination of their relentless pursuit of sonic perfection and technical innovation.

As a cornerstone of the award-winning MRX Series, the 1140 8K delivers an uncompromising blend of performance and value, a testament to Anthem’s independent engineering philosophy.

With 15.2 pre-amplifier channels and 11 amplifier channels providing a conservative 140 watts each into 8 ohms, this is the ultimate power centre for discerning audiophiles and home theatre enthusiasts.

It is an instrument of precision, designed to deliver unadulterated audio and video performance.

Anthem’s MRX A/V receivers are meticulously engineered to maximise audio performance, reaching levels previously unobtainable at their price points.

The MRX 1140 8K builds upon this foundation by incorporating the newest version of ARC Genesis with a redesigned, more accurate calibration microphone, Anthem’s intuitive Web User Interface, and robust integrated streaming support.

It features object-oriented audio codecs with support for up to 15.2 channels, ensuring an immersive sound experience.

The new electronics platform includes HDMI 2.1 with HDCP 2.3, offering 7 dedicated 8K HDMI inputs that support 8K/60Hz or 4K/120Hz pass-through, along with three dedicated outputs, including eARC.

The Science of Superiority

At Anthem, they don’t just innovate; they engineer with intent.

Every element of the MRX Series 8K is the result of careful design, rigorous testing, and a relentless pursuit of excellence.

From the precision of their amplification stages to the integrity of the 8K HDMI platform, each feature is built on one guiding principle: to preserve the truth of the performance.

Gaming, Movies, and Beyond- Uninterrupted, Uninhibited, Unmatched

Anthem’s 8K HDMI 2.1 platform is not a feature list—it’s a technical blueprint for next-generation entertainment.

With 7 dedicated 8K inputs and 2 outputs, it ensures uninhibited signal flow at 8K/60Hz and 4K/120Hz.

This is not simply about handling new formats, it is about guaranteeing the integrity of every pixel and frame, from source to screen. Features like VRR and ALLM are not afterthoughts; they are critical components of a platform built to deliver a fluid, high-fidelity experience, particularly for gaming.

ARC Genesis: The Room is No Longer an Obstacle

Acoustics are a science.

Their award-winning ARC Genesis Room Correction uses a precision microphone and advanced algorithms to solve—not mask—room issues, optimising frequency response for peak performance.

With four storable profiles, you get unmatched customisation and control.

ARC Genesis is Anthem’s flagship room correction software, designed to put the power of a professional audio lab in your hands.

Compatible with Mac and Windows, it measures your room’s unique acoustics, calculates custom correction curves, and uploads them to your ARC-compatible system — delivering accurate, balanced, and natural sound for any setup.

If you own an Anthem, Paradigm, or MartinLogan product that’s ARC- or PBK-enabled, you can unlock a new level of performance and precision by downloading the ARC Genesis software.

Experience the next generation of room correction — powerful, intuitive, and unmistakably Anthem.

New Features Include

• Support for Mac & Windows
• New Target Curve Adjustments: Customise deep bass and high-frequency response
• Flexible Measurement Options: Save, stop, start, resume measurements, and remeasure individual speakers
• Improved User Interface for easier navigation and setup
• Enhanced Algorithms for more precise corrections
• Custom Maximum Correction Frequencies for each speaker set
• Automatic Speaker/Subwoofer Phase Alignment for Anthem STR Series products

Precision-Driven, Digital-to-Analog Conversion

The MRX 1140 8K leverages 32-Bit/768 kHz DACs to deliver every digital signal with precise fidelity, ensuring a dynamic, detailed, and truly pure listening experience.

Audio Codecs: Purity Beyond Perception.

Anthem MRX integrates the latest object-oriented audio codecs—including Dolby Atmos, DTS:X, and IMAX Enhanced—not for marketing, but for the precise, three-dimensional spatialisation they enable.

Their system ensures every sound object is rendered with surgical accuracy, immersing you in an auditory landscape that is both vast and meticulously detailed.

Complexity Simplified

At Anthem, they believe a system engineered for performance without equal should be effortless to command.

They’ve gone to a meticulous degree to ensure no detail is overlooked, giving you absolute authority over your device from a phone, tablet, or laptop.

Their Web User Interface simplifies the complex, allowing you to power on a secondary zone, adjust volume, change audio modes, and tweak channel trims on the fly.

You’re in control, and it’s by their design.

Power & Flexibility: The Unseen Force

The MRX 1140 8K features seven high-performance amplifier channels powered by a robust toroidal transformer—chosen for its exceptional efficiency and ultra-low noise.

This forms the foundation of Anthem’s clean, effortless power delivery.

With intelligent channel reassignment, you can allocate power exactly where it’s needed most—whether bi-amping demanding main speakers or driving a multi-zone setup.

It’s more than flexibility; it’s engineering optimised for your unique application.

The Anthem Advantage

Drawing on their decades of hands-on design and innovative audio engineering, Anthem products deliver an unparalleled level of reliability and functionality.

This isn’t just about features; it’s about a relentless focus on a superior performance-to-price ratio that sets the industry standard.

This is the reason Anthem electronics are the definitive choice for audiophiles, professional musicians, and engineers worldwide.
