About this product
The MartinLogan USR51 is a revolutionary AV Receiver design, intended to hide where typical full size receivers simply can’t fit. The ultra-slim profile of the USR51 allows it to be mounted behind a TV using the included VESA bracket, inside a piece of furniture, or even rack mounted with the optional 1U rack mounting kit (sold separately). Despite its ultra-compact design, the USR51 features up to 5.1 channels with 50W of power per channel, perfect for a surround sound, 3.1, or Stereo system. The USR51 is also designed to integrate seamlessly with your TV thanks to its HDMI eARC input. By using the TV for input switching, the USR51 effectively operates invisibly to the user. Changing inputs and volume works exactly as it did before the USR51 was added, making for a seamless transition into the world of home theater. Of course, USR51 also comes with its own remote and is fully compatible with a variety of 3rd party control platforms as well as the Anthem Remote Control app. USR51 also features the award-winning ARC Genesis Room Correction system which will calibrate your speakers and subwoofer for the most optimal performance in your room.
Features
Ultra-Slim Form Factor
At a fraction of the size of traditional AVRs, the USR51 delivers up to 5 channels of power (50 Watts per channel into 8 Ohms, and 92 Watts per channel into 4 Ohms), ensuring you get the quality you expect without the bulky footprint.
ARC Genesis Room Correction
Includes the full feature set of the award-winning Anthem Room Correction System. Addressing the acoustic challenges of modern living spaces in minutes, ensuring peak performance in every environment by minimizing the harmful effects of hard surfaces, awkward layouts, and more.
Seamless Integration
With robust IP and IR support, the options are nearly limitless. Simply use the included IR remote or the Anthem Remote App (iOS or Android) to fully control the unit out of the box, or for more advanced installations, USR51 is fully compatible with major control systems like Savant, Control4, URC, Crestron, RTI, Elan, AVA, and Josh.ai.
Built-In Streaming
Whether the client needs a slim solution to power a pair of speakers, or a stealthy surround system, USR51’s native support for Apple AirPlay, Google Cast, Spotify Connect (Coming Soon), and Bluetooth is intended to provide a seamless user experience.
Concealed Performance
The USR51 is the perfect companion for MartinLogan’s low-profile Motion SLM Series, Motion Compact Series (2i/4i/6i/8i), Discrete Cinema Series, or with any MartinLogan in-wall or in-ceiling speakers for the ultimate low-profile sound solution.
WebUI and App Control
USR51 is designed without an On Screen Display (OSD) so things on your screen will behave the same as they always did. The TV’s OSD can display the volume level as it did before, just now running through the USR51 rather than the TV’s built-in speakers. This also helps prevent disruption of the on-screen content, as the detailed settings are adjusted in the WebUI or Control App independently of what is showing on the TV at the time.
