Anthem MRX 740 8K Home Theater AV Receiver
Overview
The Anthem MRX 740 8K sits in the middle of Anthem's MRX receiver line, built for a home theater that wants real object-based height channels without moving all the way up to the flagship. It pairs 11.2 channels of pre-amplifier processing with 7 onboard amplifier channels delivering 140 watts per channel into 8 ohms on the main five channels.
ARC Genesis room correction and two parallel subwoofer outputs tune the system to the room, and the 8K-ready HDMI 2.1 platform (7 inputs, 3 outputs including Zone 2 and eARC) keeps it ready for current and future sources. The same 32-bit/768kHz DACs found across the MRX line keep the audio path clean regardless of channel count.
Channels can be re-assigned for bi-amping or a second zone, and the Anthem Web User Interface handles day-to-day control from a browser rather than an on-screen menu.
Simcoe Audio Video Insight
We spec the MRX 740 8K most often for a 5.1.2 or 7.1 layout where the client wants room to grow into height channels without the largest receiver in the lineup. It carries the same processing and DAC quality as the flagship MRX 1140, just with fewer onboard amplifier channels and a single parallel (rather than independently calibrated) pair of subwoofer outputs.

Why the Anthem MRX 740 8K Stands Out
11.2-Channel Processing, 7 Amplified Channels
Enough onboard amplification and processing headroom for a 5.1.2 or 7.1 layout with room to grow.
ARC Genesis Room Correction
Anthem's proprietary calibration engine, included with a calibrated microphone.
8K HDMI 2.1 Platform
Seven inputs and three outputs (including Zone 2 and eARC) support 8K/60Hz and 4K/120Hz pass-through with HDCP 2.3.
32-Bit/768kHz DACs
The same digital-to-analog conversion quality found across Anthem's MRX and AVM lines.
Configurable Amp Matrixing
Channels can be re-assigned for bi-amping or a second zone rather than locked to a single layout.
Anthem Web UI & Streaming
Apple AirPlay 2, Google Chromecast, and Spotify Connect join Bluetooth for wireless playback from a browser-based interface.
Buyer's Guide
Who It's For
- The Height-Channel Adopter: Wants a 5.1.2 or 7.1 layout with real object-based processing, not just a larger 5.1 system.
- The Future-Proofing Gamer: Needs 8K/60Hz and 4K/120Hz HDMI 2.1 pass-through for next-generation consoles and displays.
- The Mid-Tier Anthem Buyer: Wants flagship-level processing and DACs without the 1140's full channel count.
How It Compares
The MRX 740 8K and the flagship MRX 1140 8K share the same ARC Genesis platform, DACs, and HDMI 2.1 video engine, but the 1140 steps up to 15.2 channels of processing, 11 amplified channels, and two independently calibrated (rather than parallel) subwoofer outputs. The 740 is the right call for a 5.1.2 or 7.1 layout; step up to the 1140 for a full object-based system with more height channels.
