About the Crestron DM-NVX-384
The two HDMI and two USB-C inputs form a 4x1 switcher in encoder mode, with inputs chosen by auto-switching, a control system or the web interface; in decoder mode it switches 5x1. The DM-NVX-384 supports 5K Ultra-Wide (21:9) and Super-Wide (32:9) formats, up to 5120x2160 at 30 Hz or 5120x1440 at 60 Hz, with HDR10, HDR10+ and Dolby Vision. H.264 encoding and streaming sit alongside Pixel Perfect Processing.
The HDMI output scales video and supports video wall processing. It also supports eARC, so audio from the connected display can be sent over the network as a multichannel BTS audio over IP stream, with a single cable handling both AV input and audio output. The secondary HDMI input supports eARC as an audio output to an AVR, and the BTS stream also works with the DM-NAX-XSP (sold separately) in zones without video.
Power comes from PoE++ (IEEE 802.3bt Type 3 Class 6, 60 W) or the optional PW-2420RU power pack, and typical consumption is 35 W. The fan-cooled black metal chassis has integral mounting flanges for freestanding, surface or single rack rail mounting and is 209 mm high, 209 mm wide and 31 mm deep. It also offers an analogue audio input or output, native AES67 transmit and receive, and USB and KVM routing.

Questions about the Crestron DM-NVX-384
What is the Crestron DM-NVX-384?
It is a DM NVX AV over IP endpoint with a built-in 4x1 input switcher for two HDMI and two USB-C sources. It can be configured as an encoder or a decoder and carries up to 5K video, including Ultra-Wide and Super-Wide formats, over standard Gigabit Ethernet with HDCP 2.3.
How are inputs selected on the DM-NVX-384?
In encoder mode the two HDMI and two USB-C inputs form a 4x1 switcher, and in decoder mode it switches 5x1. Inputs can be selected automatically in auto-switching mode, by a control system or through the web interface, with breakaway audio and Crestron QuickSwitch HD technology.
What does eARC do on the DM-NVX-384?
eARC on the HDMI output lets audio be taken from the connected display and sent over the network as a multichannel BTS audio over IP stream, with a single cable to the display. The secondary HDMI input supports eARC as an audio output, passing a multichannel audio over IP stream to a connected AVR.
How is the DM-NVX-384 powered?
It is powered by PoE++ (IEEE 802.3bt Type 3 Class 6, 60 W) from a PoE++ compliant Ethernet switch or a third-party IEEE 802.3bt compliant PSE. The PW-2420RU power pack, which supplies 24 VDC and is sold separately, is the alternative. Typical consumption is 35 W.
What is the difference between the DM-NVX-384 and the DM-NVX-385?
Both are 5K 4x1 AV over IP switchers with two HDMI and two USB-C inputs, eARC, AES67 and PoE++ power, and both measure 209 mm by 209 mm by 31 mm. The DM-NVX-385 adds surround sound to stereo downmixing; the DM-NVX-384 supports surround sound but does not list downmixing.
How much is the Crestron DM-NVX-384?
Crestron asks its dealers to give the price of the DM-NVX-384 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-NVX-384?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the DM-NVX-384 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-NVX-384 come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the DM-NVX-384 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-NVX-384 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-NVX-384 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.
