Crestron DM-NVX-385C – 5K 4x1 AV-over-IP Switcher Card, HDMI and USB-C

Product Overview

The Crestron DM-NVX-385C is a DM NVX AV-over-IP encoder/decoder card for the DMF-CI-8 card chassis, combining a built-in 4x1 input switcher with 5K AV-over-IP streaming over standard Gigabit Ethernet. It accepts two HDMI inputs and two USB-C inputs (DisplayPort Alt Mode), enabling laptop and PC connections without adapters in conference rooms, training rooms, and huddle spaces. The card operates as either a transmitter or receiver, making it a flexible component in high-density rack-based DM NVX AV distribution systems.

Product Description

The DM-NVX-385C supports video resolutions up to 5120×2880 at 30 Hz (5K Wide) and 5120×1440 at 60 Hz (5K Super-Wide), with 4:4:4 color sampling and HDR support including HDR10, HDR10+, Dolby Vision, and Deep Color. In encoder mode, it presents a 4x1 switcher accepting two HDMI inputs and two USB-C inputs, with manual, automatic, or control-system-driven switching. In decoder mode, it acts as a 5x1 switcher accepting the network stream plus an HDMI input, with a full 4K60 4:4:4 output scaler.

Audio support covers multichannel digital formats including Dolby Atmos, DTS:X, Dolby TrueHD, DTS HD Master Audio, and LPCM up to 8 channels. Native AES67 transmit and receive capability enables audio-over-IP integration with AES67-compliant systems. The card includes an analog stereo audio input/output (3.5 mm terminal block) for local monitoring or amplification. Downmixing of surround sound to stereo is supported for simpler audio outputs.

The DM-NVX-385C provides two copper Gigabit Ethernet ports and one SFP fiber port for network connectivity. USB 2.0 KVM extension is included via USB Type-A ports (TO DEVICE and HID TO DEVICE) and USB-C host ports (TO HOST), enabling keyboard, mouse, and peripheral sharing over IP in conference room and training room installations. Video wall processing supports configurations up to 8 wide by 8 high. eARC is supported on both HDMI IN 2 and HDMI OUT for audio return channel applications.

The card occupies one slot in the DMF-CI-8 card chassis (sold separately) and includes a metal faceplate. Copy protection is HDCP 2.3. Security features include AES-128 content encryption with PKI authentication, SSL/TLS, SSH, and Active Directory authentication.

Technical Specifications

Frequently Asked Questions

What chassis is required for the DM-NVX-385C?

The DM-NVX-385C requires the DMF-CI-8 card chassis (sold separately). It occupies one card slot in that chassis.

Can this card be used as either a transmitter or a receiver?

Yes. The DM-NVX-385C is configurable as a DM NVX encoder (transmitter) or decoder (receiver) via the web interface or Crestron control system, providing flexibility in system design and inventory management.

Do the USB-C inputs support video from all USB-C laptops?

The USB-C inputs require DisplayPort Alt Mode for video transmission. Not all USB-C cables and devices support DisplayPort Alt Mode; check that the source laptop and cable both support it.

What is the maximum video resolution supported?

The DM-NVX-385C supports up to 5120×2880 at 30 Hz (5K Wide) and 5120×1440 at 60 Hz (5K Super-Wide), as well as 4K60 4:4:4.

Is the SFP fiber port transceiver included?

No. The SFP port requires a Crestron SFP-1G Series transceiver module, sold separately.

Does this card replace both an encoder and a decoder card?

In a given installation, each unit functions as either an encoder or decoder (not both simultaneously). However, the same card model can be deployed in either role, reducing the number of SKUs required for a system.

What warranty applies?

Covered under Crestron's standard limited warranty. Full details at crestron.com/warranty.
