Variable Multicast TTL (Time To Live) enables traversing multiple network routers for optimal flexibility.

Support for 5K Resolutions
The DM‑NVX‑384 introduces support for 5K video resolutions including 5K Wide (5120×2880), 5K Ultra-Wide 5120 × 2160, and 5K Super-Wide 5120 × 1440, expanding the DM NVX product family’s compatibility with the latest generation of computers, monitors, and displays.

Pixel Perfect Processing Technology
A DM NVX system incorporates Pixel Perfect Processing technology, which provides flawless video transport in all applications. Depending on the operating mode, the DM‑NVX‑384 can encode or decode a video signal to achieve imperceptible end-to-end latency of less than one frame. The image quality of the source is maintained across a 1‑Gigabit network at resolutions up to 5K Wide 4:4:4.

Enterprise-Grade Security
Using advanced security features and protocols such as 802.1X authentication, Active Directory® credential management, AES-128 content encryption, PKI authentication, TLS, SSH, and HTTPS, a DM NVX system delivers a true enterprise-grade network AV solution engineered to fulfill demanding IT policies.

Encoder and Decoder Functionality
The DM‑NVX‑384 is configurable to operate as either a network AV encoder or decoder:

• As an encoder, the DM‑NVX‑384 allows the HDMI or USB‑C signal of a laptop computer, camera, or other media source to be transmitted over the network to one or many decoders.¹
• As a decoder, the DM‑NVX‑384 receives the signal from a DM NVX encoder and feeds it to a display device via the HDMI output. The decoder can quickly and easily switch between multiple encoders on the network alongside a locally connected HDMI or USB-C source.¹

The DM‑NVX‑384 provides a versatile and cost-effective solution for applications that require encoder and decoder operating modes in a single device. The operating mode can be reconfigured dynamically in less than 1 minute via a control system or web browser or can be changed by using the SETUP button.

HDMI Output with 4K60 4:4:4 Scaler
When the DM‑NVX‑384 is configured as a decoder, the HDMI output feeds the decoded signal to the HDMI input of a local display device, switcher, or other equipment. The built-in scaler ensures an optimal image, scaling the encoded source resolution up or down to match the native resolution of the display device. When the DM‑NVX‑384 is configured as an encoder, the HDMI output can be used to feed a local display, confidence monitor, or audio system.^{1, 4}

Video Wall Processing
A video wall composed of up to 64 individual displays can be configured using multiple DM NVX endpoints. Each endpoint provides fully adjustable zoom capability and bezel compensation to accommodate a range of video wall configurations and display types. One DM NVX endpoint is required per display, supporting configurations of up to eight wide by eight high.

Text Overlay
The ability to display dynamic or fixed text on screen provides a means to label the video source or to display special instructions, schedules, announcements, alerts, and other messaging.

7.1 Surround Sound Audio
DM NVX technology supports the lossless transport of 7.1 surround sound audio signals, including Dolby® TrueHD, Dolby Atmos®, DTS HD®, DTS:X®, and uncompressed linear PCM. In decoder mode, the DM‑NVX‑384 can receive both multichannel and 2-channel downmix signals from a DM-NVX-363, DM-NVX-363C, DM‑NVX‑351, or DM‑NVX‑351C encoder, allowing either signal to be selected at the HDMI output while the 2-channel signal is automatically routed to the analog output.

AES67 and DM NAX® Audio Embedding and De-embedding
AES67 support via native support for Crestron DM NAX® Audio-over-IP technology allows the selected audio source to be transmitted as a 2-channel AES67 source while another AES67 2-channel audio stream is received from a Crestron DM NAX device or other AES67 capable device and combined with the video signal.

In DM NVX encoder mode, the received AES67 audio stream can be output via the local HDMI output, primary AV stream, secondary audio stream, and analog audio output. In DM NVX decoder mode, the AES67 received audio stream can be combined with the video and then output via the HDMI output and analog audio output.

Analog Audio Embedding or De-embedding
An unbalanced stereo analog audio port is included, which can be configured as either an input or output. As an input, the port allows a stereo audio source to be connected and combined with the video signal from the HDMI input or the incoming network video stream. As an output, the port can provide a stereo line-level signal to feed a local sound system or soundbar. The output volume is adjustable via a control system or web browser.⁵

Breakaway Audio
A DM NVX decoder can select and combine separate video and audio signals from two different inputs or even two different encoders. Combining signals from two separate encoders is limited to 2-channel stereo audio.⁶

Copper or Fiber Ethernet Connectivity
The DM‑NVX‑384 includes two RJ-45 1000BASE-T ports (Ethernet ports 1 and 2) and one SFP port (Ethernet port 3). Any Ethernet port can be used to transport video over a Gigabit Ethernet network. When not used to transport network video, ports 1 and 2 can provide network connections for an AirMedia gateway, display device, or other local device. The ports can also be used to daisy-chain multiple endpoints feeding a single-source video wall or individual displays that show the same video image. Port 1 is also capable of receiving power from a POE++ compliant Ethernet switch or third-party IEEE 802.3at compliant PSE (power sourcing equipment).^{2, 7}

The SFP port enables connection to a fiber-optic network with the use of the appropriate Crestron SFP-1G Series transceiver module (sold separately). A selection of modules is offered to accommodate various multimode and single-mode fiber types.³

A DM NVX system can be deployed on an existing corporate or campus network or on a dedicated network. For information about network requirements and guidelines, refer to the DM NVX AV-over-IP System Design Guide.

USB 2.0 and KVM Integration
DM NVX technology supports the extension of USB signals, which can be switched and routed alongside the AV signal or separately via a control system. USB 2.0 TO HOST and TO DEVICE ports are provided on the DM‑NVX‑384, allowing a USB mouse, keyboard, or other peripheral device to be connected to a remote endpoint and routed to a computer or other host at the local endpoint. In addition to KVM switch functionality, various types of USB peripherals are supported, including whiteboards, touch screens, game controllers, cameras, mobile devices, headsets, and flash drives.⁸

USB 2.0 data transport can be configured for Layer 2 or Layer 3. Layer 2 supports USB signal extension in point-to-point and multipoint applications. USB signals can be routed from the TO DEVICE ports of up to seven remote DM NVX endpoints to the TO HOST port of a single local DM NVX endpoint. Layer 2 also supports Crestron USB-over-Ethernet devices (DM‑NUX‑L2 or DM‑NUX‑R2, sold separately), which can be used in locations that do not include DM NVX endpoints. USB signals can be routed between DM NVX and DM NUX devices under the management of a control system.

USB 2.0 Layer 3 data transport supports USB signal extension in DM NVX point-to-point applications across VLANs.

Device Control
The DM‑NVX‑384 includes built-in COM (RS-232) and IR ports for control of the connected display, camera, or other devices by a control system. Additional control capability is provided by CEC (Consumer Electronics Control) over the HDMI connection, potentially eliminating the need for dedicated serial cables or IR emitters.

The COM port and CEC over the HDMI output can also enable the display device to be turned on or off automatically without the use of a control system.

Web-Based Setup
Setup of the DM‑NVX‑384 is accomplished by using a web browser. Full control and monitoring of the device is enabled through integration with a control system or with a DM NVX Director® virtual switching appliance.
