Fifteen processed channels, eleven amplified
MRX1140 8K handles up to 15.2 pre-amplifier channels and provides eleven internal power-amplifier channels. The main channels reach 140 W into 8 ohms; pre-outs allow larger configurations to be completed with external amplification while retaining centralised receiver management.
HDMI 2.1 and the 8K platform
The HDMI section includes seven inputs and three outputs with HDCP 2.3, HDR, BT2020 and CEC. Anthem specifies 8K/60 Hz and 4K/120 Hz pass-through; ARC/eARC audio return carries sound back from the television, while ARC Genesis remains the room-correction system.
Dolby Atmos, DTS:X and 15.2
The 15.2 processing capability supports extensive immersive layouts with Dolby Atmos and DTS:X. Dolby TrueHD, Dolby Digital Plus, DTS-HD Master Audio, DTS Virtual:X and other multichannel decoders are also supported, with Dolby Vision and IMAX Enhanced on the video side.
ARC Genesis and calibration profiles
ARC Genesis uses the precision microphone supplied in the kit to measure interactions between loudspeakers and room and apply corrective filters. The Anthem platform can store multiple calibration profiles, useful when loudspeaker layouts, listening positions or operating modes change.
Streaming, DAC and Zone 2
The digital section combines Quad Core DSP and 32-bit/768 kHz Differential Output D/A converters with Bluetooth 4.2, AirPlay 2, Chromecast Audio, Spotify Connect, internet radio and Roon. Zone 2 Multiroom extends audio management to a second room.
Connections, power supply and control
Five digital inputs, six analogue RCA inputs and pre-outs complement the HDMI section. A toroidal transformer supplies the power stage; WebBrowser IP control, RS-232, IR, iOS/Android app, remote control and the OLED display complete system integration.
