DM-NAX-4ZSA-50

DM NAX® 4+1 Zone Streaming Amplifier

The Crestron DM-NAX-4ZSA-50 is a next generation Audio-over-IP (AoIP) amplifier with Gallium Nitride (GaN) Class D technology that fits up to 50 W of output power per channel into a half-width 1RU space. Streaming services are built-in with media player access available for each output zone.

The Crestron DM-NAX-4ZSA-50 is a next generation Audio‑over‑IP (AoIP) amplifier that puts Crestron multiroom audio distribution on the network. It provides four amplified stereo speaker outputs and one analog line-level stereo output for a total of five zones. A dedicated streaming service player for each zone enables complete freedom to stream different content in every zone.

DM NAX™ is built on AES67 standards with additional ease of configuration via a web interface, SIMPL Windows, C#, and/or a RESTful API. It is compatible with DM NVX® through the AES67 secondary audio stream. DM NAX is also compatible with third-party AES67 solutions and Dante® via the compatibility mode enabled through Dante Controller. Full DSP capabilities are available on the line and speaker outputs.

Audio-over-IP
The DM-NAX-4ZSA-50 sends and receives DM NAX and AES67 encoded audio over a standard IP network. A single DM NAX system can handle audio distribution between 32 DM NAX devices and supports up to 256 audio output zones. DM NAX devices can seamlessly pull and distribute the audio from DM NVX sources.

Streaming and Casting Services
A dedicated streaming service player is built-in for each zone, supporting AirPlay® 2, Internet Radio, Spotify Connect™, Pandora®, SiriusXM®, TIDAL™, Deezer®, Qobuz®, SOUNDMACHINE®, Podcasts and more. The DM-NAX-4ZSA-50 delivers streaming, routing, distribution, and amplification in a single device. Streams can be routed to other non-streaming AoIP devices.

Chimes
A library of chimes is built into the unit. Chimes can be assigned to different zones to help identify them. Whenever a chime is triggered, the zone audio will duck or pause, so the chime can be clearly heard over active media until the chime concludes.

Digital Signal Processing (DSP)
DSP capabilities such as bass and treble boost and cut, loudness, adjustable delay, speaker protection and limiting, tone profiles, a full 10-band EQ per output, and an option to have line output as a fixed or variable level with or without DSP applied are available. Speaker profiles for first and third party speaker models are built in to simplify output DSP tuning.

Encoder and Decoder Functionality
The DM-NAX-4ZSA-50 can operate as a network AoIP encoder and decoder. The local input sources on one amplifier can be sent as AoIP streams to DM NAX, Dante, or AES67 capable devices. Simultaneously, the DM-NAX-4ZSA-50 can receive AoIP streams from these same devices and decode them for local output.

Modular Design
The DM-NAX-4ZSA-50 is housed in a half‑width rack‑mountable form factor that can be installed individually or ganged together in a single rack space. The amplifier is high-density stackable with other Crestron DM NAX or X-Series amplifiers, allowing multiple units to be installed vertically in an equipment rack without needing extra ventilation space. Rack mount parts are included, so no additional mounting accessories or rack shelves are required.

Whether mounting in a rack or placing on a shelf, it is easy to combine two amplifiers into a single, full rack-width assembly.

Gallium Nitride (GaN) Amplification
The DM-NAX-4ZSA-50 is the first Crestron amplifier to feature GaN Class D technology. GaN amplification allows higher output power to fit into small form factors without sacrificing efficiency or audio performance. The DM-NAX-4ZSA-50 is capable of up to 50 W of amplifier output power per channel in a half-width 1RU housing that matches the depth of the DM‑NAX‑AMP‑X300.
