Anthem MRX 1140 8K Home Theater AV Receiver
Overview
The Anthem MRX 1140 8K is the flagship of the MRX receiver line, built for home theaters that need serious channel count without moving to separate components. It combines 15.2 channels of pre-amplifier processing with 11 onboard amplifier channels, so most large object-based layouts can run from a single chassis.
The main five channels deliver 140 watts per channel into 8 ohms, while the remaining six channels use more efficient power modules rated at 60 watts each, a design that puts the power where a room needs it most (the front and surround channels) without over-building the height channels. ARC Genesis room correction, with two independent subwoofer outputs, tunes the whole system to the room, and the 8K-ready HDMI 2.1 platform (7 inputs, 3 outputs) keeps it ready for current and future video sources.
Control runs through the Anthem Web User Interface and Remote App, so day-to-day adjustments don't require an on-screen menu at all.
Simcoe Audio Video Insight
We spec the MRX 1140 8K for clients who want a genuine object-based layout, up to 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 on its own timing and phase 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 on its own timing and phase 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.
Configurable Amp Matrixing
Channels can be re-assigned for bi-amping or an additional 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 Theater 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 theater 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.
