Crestron DM-NAX-AP-100 – DM NAX Intelligent Audio Processor

Product Overview

The Crestron DM-NAX-AP-100 is a compact PoE-powered audio processor that adds DSP-based acoustic echo cancellation (AEC), automatic gain control (AGC), and dynamic noise suppression to USB audio devices in conference rooms and collaboration spaces. It connects between a room’s USB audio chain and the DM NAX audio-over-IP network, allowing a laptop or UC platform to benefit from professional-grade audio processing without requiring a dedicated DSP system. AV integrators and IT managers use it in rooms where USB conference systems need improved call quality without a complex audio infrastructure deployment.

Product Description

The DM-NAX-AP-100 appears to connected computers as a "Crestron Echo-Canceling Speakerphone" USB device (UAC2 class compliant), requiring no special drivers on the host machine. It accepts USB stereo audio bidirectionally (up to 24-bit/48 kHz) and simultaneously encodes and decodes DM NAX / AES67 audio-over-IP streams. Two Ethernet ports are provided: LAN 1 accepts PoE (IEEE 802.3af) for power and control, and LAN 2 is a dedicated audio-over-IP port for the AES67 network. The device mounts via an included bracket and fits in a 1.35 in. profile for under-table or wall-box installations.

Frequently Asked Questions

Q: Does the DM-NAX-AP-100 require any software or drivers on the connected computer?
A: No. The DM-NAX-AP-100 is a UAC2 class-compliant USB audio device and is recognized by any modern operating system as a standard USB audio device without requiring the installation of drivers or Crestron software on the host computer.

Q: Can the DM-NAX-AP-100 be used without a DM NAX network?
A: Yes. The DM-NAX-AP-100 can function as a USB echo-canceling audio processor independent of a DM NAX network, providing AEC, AGC, and noise suppression for the USB audio path. The AES67 audio-over-IP capability on LAN 2 is used when integrating into a DM NAX or AES67 network.

Q: How is the DM-NAX-AP-100 mounted?
A: The unit is 1.35 in. high and includes a mounting bracket that increases the height to 1.77 in. It can be mounted under tables, inside furniture, or in other concealed locations common in conference room AV infrastructure.
