The Crestron DM NAX 4ZSP is a network-based preamplifier that facilitates multi-zone audio distribution using audio-over-IP technology. Developed to meet the demands of modern commercial and residential environments, the DM NAX 4ZSP delivers four stereo zones via eight line-level outputs, each with individual access to built-in streaming services. It supports advanced audio management and routing through integration with the DM NVX platform, third-party AES67 systems, and Dante-enabled devices using AES67 compatibility mode. The DM NAX 4ZSP is particularly suited for environments requiring flexible audio zoning, such as enterprise campuses, hospitality venues, retail installations, and high-end residential projects.

Equipped with a dedicated streaming media player for each zone, the Crestron DM NAX 4ZSP allows distinct content to be delivered across multiple spaces simultaneously. This is supported by full DSP capabilities, enabling precise control over equalisation, output levels, delay, and tone. Audio busses allow zones to be permanently linked or dynamically grouped, enhancing configuration flexibility. The inclusion of a built-in chime library, voice control compatibility with Crestron Home OS, and support for remote configuration via web interface, SIMPL programming, C#, or RESTful API ensures that the DM NAX 4ZSP integrates reliably within broader control ecosystems. With a compact 1 RU design, low power usage, and consistent performance, the DM NAX 4ZSP provides a robust solution for scalable, networked audio deployment.
