About the Crestron DM-NVX-385C
The two HDMI and two USB-C inputs give 4x1 switching in encoder mode and 5x1 in decoder mode, with manual or auto-switching and breakaway audio. The card handles 4K60 4:4:4 video and 5K Ultra-Wide (21:9) and Super-Wide (32:9) resolutions, up to 5120x1440 at 60 Hz, with HDR10, HDR10+ and Dolby Vision, and adds H.264 encoding and streaming.
Surround sound can be downmixed to stereo, alongside primary multichannel audio of up to 8-channel LPCM or HBR 7.1 and secondary 2-channel LPCM. In decoder mode the HDMI output has a 5K scaler, and video wall processing is built in. With eARC, display audio can go back over the network as a multichannel BTS stream, and the secondary HDMI input can feed a multichannel stream to an AVR.
The DM-NVX-385C occupies one slot in a DMF-CI-8, a 2-space rack chassis that houses up to eight DM-NVX-C or DMCF series cards in any slot. The chassis provides hot-swappable card servicing, network setup for each card through its front panel and a universal 100 to 240 V internal power supply. Native AES67 transmit and receive and USB and KVM routing are also supported.

Questions about the Crestron DM-NVX-385C
What is the Crestron DM-NVX-385C?
It is a DM NVX AV over IP encoder/decoder card with a 4x1 switcher for two HDMI and two USB-C inputs and surround sound to stereo downmixing. It occupies one slot in a DMF-CI-8 card chassis and carries 4K60 4:4:4 and 5K wide format video over standard Gigabit Ethernet.
How does the DM-NVX-385C differ from the DM-NVX-384C?
Both are 5K 4x1 AV over IP switcher cards with two HDMI and two USB-C inputs and eARC, and both occupy one slot in a DMF-CI-8 card chassis. The DM-NVX-385C adds surround sound to stereo downmixing, which the DM-NVX-384C does not list among its features.
Which chassis does the DM-NVX-385C fit?
It occupies one slot in a DMF-CI-8, a 2-space 19-inch rack-mountable chassis for up to eight DM-NVX-C or DMCF series cards, with any card in any slot. The chassis offers hot-swappable card servicing, a 2 inch colour LCD with status indicators, network setup for each card from the front panel, and variable-speed fan cooling.
Can the card return audio from the display?
Yes. The HDMI output supports eARC, so audio can be taken from the connected display and sent over the network as a multichannel BTS audio over IP stream. The secondary HDMI input also supports eARC as an audio output to a connected AVR, and the BTS stream works with the DM-NAX-XSP.
Which video formats does the DM-NVX-385C support?
It supports 5K Ultra-Wide (21:9) at up to 5120x2160 at 30 Hz and 5K Super-Wide (32:9) at 5120x1440 at 60 Hz, as well as 4K60 4:4:4, with HDR10, HDR10+ and Dolby Vision. Custom resolutions are supported at pixel clock rates up to 600 MHz, and content is protected by HDCP 2.3.
How much is the Crestron DM-NVX-385C?
Crestron asks its dealers to give the price of the DM-NVX-385C 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-385C?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the DM-NVX-385C 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-385C come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the DM-NVX-385C 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-385C 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-385C 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.
