About the Crestron DM-NVX-384C
Its two HDMI and two USB-C inputs form a 4x1 switcher in encoder mode, and it switches 5x1 in decoder mode. Inputs are chosen by auto-switching, a control system or the web interface. The card handles 4K60 4:4:4 and 5K Ultra-Wide (21:9) and Super-Wide (32:9) formats, including 5120x1440 at 60 Hz, with HDR10, HDR10+ and Dolby Vision, and offers H.264 encoding alongside Pixel Perfect Processing.
In decoder mode the HDMI output has a 5K scaler, and video wall processing is built in. With eARC on the display connection, audio from the display can be sent over the network as a multichannel BTS audio over IP stream, and the secondary HDMI input can pass a multichannel stream to a connected AVR. The DM-NAX-XSP (sold separately) can also use the BTS stream in zones without video.
The DM-NVX-384C occupies one slot in a DMF-CI-8 card chassis. That 2-space rack chassis houses up to eight DM-NVX-C or DMCF series cards in any slot, supports hot-swappable card servicing and allows network setup of each card from its front panel. The card's operating mode can be changed in less than a minute from a control system or a web browser.

Questions about the Crestron DM-NVX-384C
What is the Crestron DM-NVX-384C?
It is a DM NVX AV over IP encoder/decoder card with a built-in 4x1 switcher for two HDMI and two USB-C inputs. It occupies one slot in a DMF-CI-8 card chassis and works as a transmitter or receiver, carrying up to 5K video over standard Gigabit Ethernet.
How does the DM-NVX-384C differ from the DM-NVX-384?
Both have the 4x1 HDMI and USB-C switcher, eARC, 5K Ultra-Wide and Super-Wide support and H.264 streaming. The DM-NVX-384C is a card for one slot of a DMF-CI-8 chassis, aimed at high-density racks. The DM-NVX-384 is a standalone unit powered by PoE++ or a PW-2420RU power pack.
Which chassis does the DM-NVX-384C need?
It occupies one card slot in a DMF-CI-8, a 2-space 19-inch rack-mountable card chassis. The DMF-CI-8 houses up to eight DM-NVX-C or DMCF series cards in any slot, has a universal 100 to 240 V internal power supply, and allows each card's network setup from its front panel.
What does eARC do on this card?
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. The secondary HDMI input supports eARC as an audio output to a connected AVR, and the BTS stream is also compatible with the DM-NAX-XSP, sold separately.
Can the DM-NVX-384C be used as a decoder?
Yes. The card can be set as an encoder or a decoder, and the operating mode can be changed in less than a minute from a control system or a web browser. As a decoder its HDMI output has a 5K scaler with motion-adaptive deinterlacing and intelligent frame rate conversion.
How much is the Crestron DM-NVX-384C?
Crestron asks its dealers to give the price of the DM-NVX-384C 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-384C?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the DM-NVX-384C 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-384C come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the DM-NVX-384C 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-384C 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-384C 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.
