Packed with Features
Like its big brother, the DM-NAX-4ZSA-50 is loaded with features, including:
Best-in-Class 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 no less than 32 DM NAX technology devices and supports up to 256 audio output zones. Additionally, 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 into the unit for each zone, supporting AirPlay® 2 software, Amazon® Music, internet radio, Spotify Connect, Pandora®, SiriusXM®, TIDAL®, Deezer®, and Qobuz® music services, podcast providers, and many, many more. The DM-NAX-4ZSA-50 delivers streaming services, routing, distribution, and amplification in a single device, and 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 so that alerts specific to an area can be recognized immediately. When a chime is triggered, the zone audio will duck or pause so the chime can be clearly heard over any active media until the chime concludes.
Outstanding 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® audio networking, or AES67-capable devices. The DM-NAX-4ZSA-50 can also simultaneously receive AoIP streams from these same devices and decode them for local output.
A Small Footprint and 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 with other amps in a single rack space. It’s 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 an installation calls for mounting in a rack or placing on a shelf, it’s very easy to combine two amplifiers into a single, full rack-width assembly.
Gallium Nitride (GaN) Amplification
Here’s where some of the real magic happens in this diminutive powerhouse: The DM-NAX-4ZSA-50 is the first Crestron amplifier to feature GaN Class D technology. That means more boom in a smaller box: 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 50 watts of amplifier output power per channel in a half-width 1RU housing that matches the depth of the DM-NAX-AMP-X300.
