Anthem MRX 740 8K 11.2 AV Receiver

The Anthem MRX 740 8K 11.2 AV Receiver is best described as an 11.2-channel pre-amplifier / processor with 7 built-in amplifier channels.

That means it can power a 5.1.2 or 7.1 speaker layout on its own, or process up to 11.2 channels when paired with additional external amplification. Anthem rates channels 1 to 5 at 140 watts per channel into 8 ohms, while the remaining two amplifier channels are rated at 60 watts per channel into 8 ohms, measured from 20Hz to 20kHz with two channels driven at 1% THD.

It also includes HDMI 2.1, 8K/60Hz and 4K/120Hz pass-through, Dolby Atmos, DTS:X, IMAX Enhanced, ARC Genesis room correction, 32-bit / 768kHz DACs, streaming support, Anthem’s Web User Interface, and integration support for major control systems.

What We Like

At Rapallo, the Anthem MRX 740 8K is the sweet spot in the Anthem MRX range for many serious home theatre systems.

Compared with the MRX 540 8K, the MRX 740 8K gives you more amplifier channels, more processing flexibility, and a stronger pathway into immersive audio. It can run a proper 5.1.2 Dolby Atmos system without needing an extra amplifier. However, it also gives you 11.2-channel processing, so you can add external power amps later and build a larger system around it.

The biggest reason to choose Anthem is still ARC Genesis. In NZ homes, room acoustics can make or break a home theatre system. ARC Genesis measures the speakers and room, then applies correction to improve tonal balance, bass integration, and overall clarity. Anthem also supports four storable ARC profiles, which is useful for different listening setups.

For customers who want performance first, the MRX 740 8K is a very strong choice. It does not just chase feature count. Instead, it focuses on clean power, accurate processing, excellent room correction, and long-term system flexibility.

Key Features

11.2 Processing with 7 Built-In Amplifier Channels

The MRX 740 8K includes 11.2 pre-amplifier channels and 7 amplifier channels. This makes it ideal for 5.1.2, 7.1, or externally expanded 7.1.4-style systems. It is a stronger foundation than the MRX 540 8K for customers wanting a more immersive setup.

Strong Amplifier Platform

Anthem rates channels 1 to 5 at 140W into 8 ohms and 170W into 6 ohms. The remaining two amplifier channels are rated at 60W into 8 ohms and 75W into 6 ohms. These figures are measured from 20Hz to 20kHz with two channels driven at 1% THD.

ARC Genesis Room Correction

ARC Genesis is a major strength of the MRX 740 8K. It uses a precision microphone and advanced software to measure your room, then creates correction filters for improved frequency response and system balance. This is especially useful for subwoofer integration and challenging room layouts.

Four ARC Profiles

The MRX 740 8K supports up to four storable ARC profiles. For example, you can create different profiles for movies, music, late-night listening, or different seating positions.

HDMI 2.1 with 8K and 4K/120Hz

The MRX 740 8K includes Anthem’s HDMI 2.1 platform with HDCP 2.3. It has 7 dedicated 8K HDMI inputs and dedicated HDMI outputs with eARC support. It supports 8K/60Hz and 4K/120Hz pass-through for modern video sources.

Gaming-Ready Video Features

The HDMI platform supports features such as VRR and ALLM. This makes the MRX 740 8K suitable for PlayStation 5, Xbox Series X, gaming PCs, and modern displays that support 4K/120Hz gaming.

Dolby Atmos, DTS:X and IMAX Enhanced

The MRX 740 8K supports immersive audio formats including Dolby Atmos, DTS:X, and IMAX Enhanced. This gives movie soundtracks more height, movement, scale, and placement when used with the right speaker layout.

32-Bit / 768kHz DACs

Anthem lists 32-bit / 768kHz DACs in the MRX 740 8K. This supports precise digital-to-analogue conversion for movie soundtracks, music streaming, gaming, and digital sources.

11.2 Pre-Outs for Expansion

The MRX 740 8K includes 11.2-channel preamp outputs. This gives you a clean upgrade path. You can add external amplifiers for height channels, front channels, or even move toward a full separates-style system.

Streaming Built In

The MRX 740 8K supports Apple AirPlay, Google Cast, Spotify Connect, and Bluetooth. That makes it useful for everyday music playback as well as home theatre.

Anthem Web User Interface

The Web User Interface lets you control setup from a phone, tablet, or laptop on the same network. You can adjust inputs, volume, listening modes, channel trims, and system settings more easily than using only the front panel.

Custom Install Friendly

The MRX 740 8K supports IP and serial control. It is also designed for integration with major control systems, making it suitable for custom home theatre and smart-home projects.

Perfect System Match

A great match would be the Anthem MRX 740 8K, a quality 5.1.2 speaker package, and a capable subwoofer. Add ARC Genesis calibration and the system becomes much better matched to the room.

For a premium Rapallo home theatre system, pair it with Paradigm speakers and an SVS subwoofer. Anthem and Paradigm are a natural match because both brands focus on accuracy, controlled sound, and proper room integration.

For a larger room, add a separate power amplifier. This lets the MRX 740 8K use its 11.2-channel processing and expand beyond its seven internal amplifier channels.
