The Anthem MRX 1140 8K is the flagship AV receiver in the MRX Series, combining 11 channels of onboard amplification with processing for up to 15.2 channels. Designed for advanced home theater installations, it provides the flexibility required for immersive Dolby Atmos and DTS:X speaker configurations while maintaining the high-performance audio standards associated with Anthem electronics.
Its amplifier section utilizes a hybrid architecture featuring high-power Class AB amplification for the primary channels and dedicated Class D amplification for surround and height channels. This approach allows the receiver to deliver substantial power reserves, excellent channel control, and efficient operation across complex multi-speaker systems. A high-current toroidal power supply further supports dynamic performance during demanding movie soundtracks and music playback.
The MRX 1140 8K incorporates a premium 32-bit/768kHz DAC platform along with Anthem's ARC Genesis room correction technology. ARC Genesis analyzes room acoustics and applies detailed calibration to improve tonal balance, imaging, and bass integration, helping the system achieve optimal performance within the listening environment.
HDMI 2.1 connectivity includes seven inputs and three outputs with support for 8K/60Hz and 4K/120Hz video, HDR10+, Dolby Vision, HLG, and eARC compatibility. Integrated streaming support, advanced control options, and 15.2-channel processing capability make the MRX 1140 8K a comprehensive solution for premium home cinema systems requiring both flexibility and reference-level performance.
