Anthem MRX 1140 8K AV Receiver

Reference 15.2-Channel Processing Meets Hybrid Multi-Channel Power

Inspiration drawn from uncompromising cinematic engineering meets ultra-modern home theater innovation. The Anthem MRX 1140 8K is Anthem’s flagship multi-channel A/V receiver, combining a 15.2-channel preamplifier with 11 channels of high-current built-in amplification in a single chassis.

Housed in a sleek, two-tone chassis featuring a high-resolution front display and minimalist tactile controls, the MRX 1140 8K pairs refined Canadian craftsmanship with Anthem's most advanced digital processing and room-calibration architecture.

Engineering Marvel: Class AB & Class D Hybrid Topology, Subterranean Precision

Don't let its single-chassis footprint deceive you. Under the hood, the MRX 1140 8K features a hybrid amplification design—utilizing high-current Class AB amplification for the demanding front channels (140W into 8Ω) alongside energy-efficient Class D amplification for surround and height channels (60W into 8Ω). Powered by 32-Bit / 768 kHz DACs and a robust toroidal transformer, it processes up to 15.2 discrete channels with complete spatial authority and zero signal degradation.

Key Performance & Technological Innovations

15.2 Processing / 11 Amplified Channels: Powers up to a 7.2.4 Dolby Atmos® or DTS:X® configuration natively, with pre-outs to expand up to 15.2 channels (9.2.6 spatial layout).

Hybrid Class AB / Class D Power: 5 primary channels driven by high-current Class AB (140W @ 8Ω) and 6 remaining channels driven by high-efficiency Class D (60W @ 8Ω).

32-Bit / 768 kHz DAC Architecture: Audiophile-grade digital-to-analog conversion on every channel ensures ultra-low distortion and expansive dynamic range.

ARC® Genesis Room Correction: Advanced room acoustic calibration powered by a high-precision calibrated microphone, managing frequency response, phase, and time alignment for all channels and dual independent subwoofers.

Advanced 8K HDMI 2.1 Platform: Features 7 dedicated HDMI 2.1 inputs and 3 HDMI outputs (with eARC) supporting 8K/60Hz, 4K/120Hz pass-through, HDR10+, Dolby Vision, VRR, and ALLM.

Web-Based UI & App Control: Granular control over setup, ARC profiles, virtual inputs, amp re-assignment, and zone settings accessible instantly via tablet, phone, or laptop.
