Anthem MRX SLM 4K Slimline 5-Channel AV Receiver
A 1U-height five-channel AV receiver designed for installations where a full-size chassis will not fit, combining 50W-per-channel amplification, HDMI eARC, wireless streaming and Anthem Room Correction Genesis.
The MRX SLM is different from most AV receivers because compact installation is the starting point rather than an afterthought. Its chassis is only 43mm high with feet and can be used in a cabinet, rack or discreetly behind a compatible display installation.
That smaller form does come with a clear system brief. This is a five-channel receiver, so it is aimed at well-executed 5.1 rooms and other compact layouts rather than large 7.x.4 cinemas.
Five Channels in a 1U-Scale Chassis
Built for places where conventional AV hardware is simply too large.
Anthem specifies 50W per channel into 8 ohms across five channels. The chassis is 279mm wide and 279mm deep, or 432mm wide with the rackmount kit, and can occupy 1U in a rack.
The physical format opens up useful installation options, but it also makes planning important. Cable bend radius, ventilation, access to HDMI connections and service access need to be considered before the unit disappears behind a television or into joinery.
Anthem Room Correction Genesis
The feature that separates it from many compact AV solutions.
ARC Genesis is included to measure the room and apply correction to the loudspeaker and subwoofer system. In small media rooms, where speakers are often closer to walls and seating positions are constrained by furniture, that can be especially valuable.
Room correction cannot fix poor speaker positions or an undersized subwoofer, so the best result still starts with sensible layout and calibration rather than relying on software to rescue the room afterwards.
HDMI eARC and a Focused Connection Set
Designed around modern television-based systems.
The MRX SLM 4K uses HDMI 2.0b with eARC and HDCP 2.3, supporting the sort of system where the television is the main video hub and the receiver handles multichannel audio. Wireless streaming is included for everyday music use.
Because the product is deliberately compact, buyers should compare the actual connection requirements against the system before ordering. If there are many legacy sources, extensive analogue connections or a large future Atmos plan, a conventional full-size MRX receiver is the better platform.

Important Notes
- The MRX SLM is a five-channel receiver. Confirm the speaker layout before choosing it for an Atmos or larger surround system.
- Compact mounting still requires ventilation, cable access and service access.
- Its connection set is intentionally focused; check every source device before finalising a concealed installation.
The Audio Experts Take
We have the MRX SLM on the floor because it solves a very specific installation problem well. It is for rooms where a normal AV receiver is physically awkward or visually intrusive, but the customer still wants proper speaker amplification and Anthem Room Correction rather than falling back to a basic soundbar. Five amplified channels define the system: think high-quality 5.1 television and movie rooms, compact media rooms, bedrooms or discreet custom installations. If the brief includes a larger Atmos layout or lots of source equipment, move to a full-size receiver. If the brief is clean installation, five real speakers and strong room correction in very little space, the SLM is unusually well targeted.
