Anthem MRX 740

The Anthem MRX 740 occupies a position of rare authority in the mid-range of Anthem's receiver lineup — a 7.2-channel A/V receiver that delivers the engineering integrity and acoustic performance Anthem have built their reputation on, at a price point that makes genuinely world-class home cinema accessible. With ARC Genesis room correction, 140 watts per channel of clean amplification, and a comprehensive 8K HDMI implementation, the MRX 740 sets a standard that competitors at this price point cannot match.

ARC Genesis — The Room Correction Standard

The MRX 740 is equipped with the latest version of ARC Genesis — Anthem Room Correction Genesis — the most sophisticated room correction system available in any receiver in its class. A redesigned, more accurate calibration microphone works in conjunction with Anthem's proprietary measurement algorithms to map the acoustic signature of your room across the full frequency range. ARC Genesis then applies mathematically precise corrections that eliminate the bass coloration, frequency smearing, and imaging collapse that untreated room acoustics impose on even the finest speaker systems. The outcome is a soundstage of extraordinary coherence — precise imaging, low-level detail retrieved cleanly from the signal, and bass that is tight, controlled, and articulate rather than bloated and indistinct. ARC Genesis is accessible and adjustable via Anthem's Web User Interface from any device on the network.

Power Delivery

Anthem approach amplifier design with an uncompromising discipline rarely seen outside dedicated power amplifier manufacturers. The MRX 740 delivers 140 watts per channel — a figure measured with all channels driven simultaneously, not the single-channel measurements used to inflate the specifications of lesser receivers. This clean, stable power delivery gives demanding speaker loads the current and headroom they require, ensuring that every channel in a 7.2-channel system performs with the same authority and composure under the most dynamic programme material.

Object-Based Audio

The MRX 740 supports Dolby Atmos, DTS:X, and IMAX Enhanced — the full suite of object-based audio codecs that define the state of the art in immersive home cinema. Up to 15.2 channels of processing capability means the MRX 740 is not constrained by its physical amplifier channels — pair it with an external power amplifier such as the Anthem MCA 225 GEN 2 or Anthem MCA 325 GEN 2 and the system scales to meet the demands of the most ambitious installation. Object placement, height channel rendering, and spatial accuracy are handled with the precision these formats demand and that Anthem's processing engine is built to deliver.

8K Video and HDMI Connectivity

Seven dedicated 8K HDMI inputs — each supporting 8K/60Hz or 4K/120Hz pass-through — and three dedicated outputs including eARC give the MRX 740 the connectivity to serve as the unambiguous hub of a modern home cinema. Dolby Vision, HDR10, and Hybrid Log Gamma are all supported, ensuring that picture quality from every source reaches the display without compromise. 8K readiness future-proofs the installation against the continuing advance of display technology.

Integrated Streaming

The MRX 740 includes integrated streaming support, allowing direct access to music services without an additional source device in the signal chain. Anthem's Web User Interface provides full system control and ARC Genesis management from a smartphone, tablet, or browser — a receiver designed for the realities of how home cinema systems are used and configured today.

Technical Specifications

Who Is It For?

The MRX 740 is the natural choice for the serious home cinema enthusiast who demands Anthem-grade performance without stepping into flagship territory. It is the centrepiece of a 7.2-channel system that punches well above its price — and with pre-amplifier outputs and support for up to 15.2 channels of processing, it grows with the installation. Those seeking a more accessible entry point into the Anthem ecosystem should consider the Anthem MRX 540 8K, while those building a no-compromise reference system will find the Anthem MRX 1140 8K the logical destination. For subwoofer matching, the Paradigm XR11 Subwoofer and Paradigm XR13 Subwoofer are outstanding partners.
