Anthem MRX 1140 8K Home Theater AV Receiver
Overview
A full object-based theatre usually means a rack of separate components. The Anthem MRX 1140 8K is the flagship of Anthem's MRX receiver line, combining 15.2 channels of processing with 11 amplified channels in one chassis, so a 7.2.4 speaker layout can run entirely from a single receiver.
The first five channels deliver 140 watts each into 8 ohms (two channels driven), and the remaining six are rated at 60 watts each, all fed by a toroidal transformer. ARC Genesis room correction, with Anthem's redesigned calibration microphone, tunes the system to your room through two independent subwoofer outputs, and 32-bit/768kHz DACs handle the conversion.
Seven HDMI 2.1 inputs and three outputs, including Zone 2 and eARC, pass 8K/60Hz and 4K/120Hz video with VRR and ALLM for gaming. AirPlay, Google Cast, Spotify Connect, and Bluetooth are built in, and the Anthem Web User Interface and Remote App handle day-to-day control.
Simcoe Audio Video Insight
We spec the MRX 1140 8K for clients who want a genuine object-based layout, such as 7.2.4, without stepping up to separate processor and amplifier boxes. The two independent subwoofer outputs are the detail that matters most in larger rooms: ARC Genesis can calibrate each sub separately rather than treating them as a single blended source.

Why the Anthem MRX 1140 8K Stands Out
15.2-Channel Processing, 11 Amplified Channels
Enough onboard processing and amplification to run a large object-based layout from one chassis.
Two Independent Subwoofer Outputs
ARC Genesis calibrates each subwoofer separately rather than as a single blended output.
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
High-resolution digital-to-analog conversion keeps the signal clean across all 15.2 processed channels.
Flexible Channel Reassignment
Amplifier channels can be reassigned for bi-amping demanding main speakers or driving a second zone, rather than being locked to a single layout.
Anthem Web UI & Streaming
Apple AirPlay 2, Google Chromecast, and Spotify Connect join Bluetooth for wireless playback, all managed from a browser.
Buyer's Guide
Who It's For
- The Zero-Compromise Theatre Builder: Wants a full object-based layout with height channels and dual subwoofers from a single receiver.
- The Future-Proofing Gamer: Needs 8K/60Hz and 4K/120Hz HDMI 2.1 pass-through for next-generation consoles and displays.
- The Multi-Zone Homeowner: Wants a centralized receiver that can run a main theatre and a second zone from re-assignable amp channels.
How It Compares
The MRX 1140 8K and the MRX 740 8K share the same ARC Genesis platform and HDMI 2.1 video engine, but the 1140 steps up to 15.2 channels of processing, 11 amplified channels, and two independent (rather than parallel) subwoofer outputs. For a full object-based layout with height channels, the 1140 is the right call; for a more contained 5.1 or 7.1 setup, the 740 covers it with less amplifier to spare.
