The DM‑NAX‑AUD‑USB is a DM NAX® encoder and decoder with support for USB audio and analog line-level audio input and output. The device is housed in a versatile form factor that can be mounted in a single-gang standard electrical box, under a table, or on a rack rail. An additional polycarbonate label is included with rotated text to make the front panel more legible in electrical box installations. Two 1/8 in. (3.5 mm) TRS connectors for analog line-level audio input and output are also included on the front panel. The rear panel of the device features an Ethernet connection for PoE, Audio over IP (AoIP), and control.
DM NAX is built on the 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 and also with third-party AES67 solutions and Dante via the compatibility mode enabled through Dante Controller.
USB Audio
A USB-C® connector is built-in to the front panel of the DM‑NAX‑AUD‑USB, allowing for bidirectional stereo USB audio transfer at rates up to 24-bit/48 kHz. This stereo signal can be output as a DM NAX AoIP stream onto the network or as an unbalanced line-level analog signal from the local 1/8 in. (3.5 mm) audio output connector.
Audio-over-IP
DM NAX takes audio distribution to a whole new level by putting it on the network. The DM‑NAX‑AUD‑USB 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.
Digital Signal Processing (DSP)
DSP capabilities such as bass and treble boost and cut, loudness, adjustable delay, tone profiles, and a full 10-band EQ per output are available on each output channel of the DM-NAX-AUD-USB.
Encoder and Decoder Functionality
The DM‑NAX‑AUD‑USB can operate as a network AV encoder and decoder. The local input sources on the adapter can be sent as AoIP streams to DM NAX, Dante, or AES67 capable devices. Simultaneously, the DM‑NAX‑AUD‑USB can receive AoIP streams from these same devices and decode them for local output.
