About the Crestron DM-NAX-AUD-IO
The DM-NAX-AUD-IO turns an analogue line-level source into a DM NAX or AES67 stream, and turns a network stream back into an analogue line-level output. Input and output are on 5-pin detachable terminal blocks and handle up to +21 dBu (8.7 Vrms). It connects directly to a managed network to route audio to or from other DM NAX and DM NVX devices, and is interoperable with Dante devices through AES67.
Crestron quotes a frequency response of 20 Hz to 20 kHz ±0.5 dB, THD+N of 0.005% and a signal to noise ratio of 110 dB from the line input, measured at the line-level output. Processing includes source compensation of ±10 dB, signal detection, balance and EQ with high pass, low pass, shelf and notch filters. Setup is through a web interface, and SIMPL Windows programming integrates it with a Crestron system.
It is powered by PoE (IEEE 802.3af Class 0) and uses 5 W. The included hardware allows mounting in a 1-gang electrical box or plaster ring (not included), under a table or on a rack rail, and an additional polycarbonate label with rotated text is included to keep the front panel legible. The metal chassis has a black and silver finish and measures 41 mm high, 66 mm wide and 54 mm deep.

Questions about the Crestron DM-NAX-AUD-IO
What is the Crestron DM-NAX-AUD-IO?
It is a DM NAX audio-over-IP converter, working as both an encoder and a decoder. It adds a stereo balanced or unbalanced line-level analogue input and output to a DM NAX audio distribution network, and can route audio to or from other DM NAX and DM NVX devices.
What connectors does the DM-NAX-AUD-IO use?
The analogue input and output are each on a 5-pin 3.5 mm detachable terminal block, carrying stereo balanced or unbalanced line-level audio at up to +21 dBu (8.7 Vrms). The network connection is an RJ-45 port for 100BASE-TX/1000BASE-T Ethernet, which also supplies PoE power.
How is the DM-NAX-AUD-IO powered?
It is powered by Power over Ethernet, compliant with IEEE 802.3af Class 0, and works with an IEEE 802.3af compliant switch or third-party PoE source. Power consumption is 5 W, so no local power supply is needed where it is mounted.
Where can it be mounted?
Included hardware lets it be mounted in a 1-gang electrical box or plaster ring (not included), under a table or on a rack rail. An additional polycarbonate label with rotated text is included to keep the front panel legible. The unit measures 41 mm high, 66 mm wide and 54 mm deep.
Does it work with Dante?
It is interoperable with Dante audio networking devices through AES67 compatibility. Its audio-over-IP input and output support DM NAX and AES67 streams, and it connects directly to a managed network. Setup is through a web interface, with SIMPL Windows programming for Crestron system integration.
How much is the Crestron DM-NAX-AUD-IO?
Crestron asks its dealers to give the price of the DM-NAX-AUD-IO directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the DM-NAX-AUD-IO?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the DM-NAX-AUD-IO on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the DM-NAX-AUD-IO come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the DM-NAX-AUD-IO develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the DM-NAX-AUD-IO in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the DM-NAX-AUD-IO without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
