Bridging the gap between streaming TVs and multi-room audio with a best-in-class ARC/eARC device

Jan. 29, 2024 - The number of content sources and services available to consumers seems to be growing daily — and with that growth comes inevitable technical challenges, especially when it comes to distributed audio. Getting sound from Point A — say, a streaming service via a device of some kind — to Point B — a zone of speakers and, ultimately, your ears — can be quite a puzzle.

Crestron’s introduced a solution that solves that puzzle in some of the thorniest use cases: The DM-NAX-XSP Audio Return Processor. A significant benefit: This groundbreaking device — our first Surround Sound decoding DM NAX® digital signal processor — can bridge streaming TVs to Crestron’s DM NAX multi-room audio distribution system.

In recent years, streaming TVs have become an increasingly popular audio source, hosting popular apps such as Netflix, Hulu, Amazon Prime, and so on — their simplicity and ease-of-use are often preferred over external boxes or dongles. Until now, there’s been no easy way to bridge this with an audio distribution system for premium in-room or multi-room audio. Now it’s possible — over the network and with the flexibility of the DM NAX platform — all thanks to the DM-NAX-XSP Audio Return Processor.

The Power of the DM-NAX-XSP

When combined with our DM NAX platform (and any of the solutions offered within that robust ecosystem), the DM-NAX-XSP truly shines. Simply put, the DM-NAX-XSP pairs seamlessly with any Crestron DM NAX amp or preamp to bring HDMI® connectivity, eARC, and ARC audio video support and immersive audio from Dolby Atmos® or DTS:X® formats. The device offers multi-channel audio inputs with a two-channel DM NAX downmix out with 8K HDMI® inputs and outputs, along with two network ports, one with PoE.

By leveraging ARC/eARC, the device can grab high-quality audio content from smart TVs and tie that to your DM NAX technology solution. By linking two of these units together, the first can extend the ARC/eARC signal over IP to a rack where a second unit can feed a traditional AVR from there.

Now, your clients can enjoy streaming content via all their in-ceiling speakers connected to a DM NAX amp — and it all works brilliantly together when coupled with the Crestron Home® OS.

It includes 8K HDMI connectivity inputs and outputs, ARC/eARC inputs, and a DSP decoder supporting up to 16 channels in and two channels out via a DM NAX downmix. It allows the user to send multi-channel audio into an AV receiver, integrating the capabilities of DM NAX Audio-over-IP Technology and DM NVX® AV-over-IP technology. The local HDMI input means you don’t lose an input to your display by adding this device — one can connect, for example, an Apple TV® digital media extender or gaming console that feeds the display — while at the same time sending Surround Sound or a two-channel downmix onto the network. And it allows the user to hear what’s happening on a single display no matter where they are in the home: Need to grab a snack? Follow the action with a two-channel feed in the kitchen while the rest of the family enjoys Surround Sound in the family room.

Installation of the DM-NAX-XSP is a breeze, with options for an in-room box or surface mounting. Its compact design and sleek aesthetics allow for frictionless integration into any audio distribution setup.
