HDMI® and USB-C® 4x1 Input Auto-Switching

The DM-NVX-385 includes two HDMI inputs and two USB-C inputs that comprise a 4x1 input switcher. Switching between the four inputs can be performed automatically using auto-switching mode, programmatically via a control system, or through the web interface. When mounted behind a conference room display device, the HDMI input provides a convenient way to connect a Crestron AirMedia® presentation gateway, video-conferencing codec, or small form factor computer. The USB‑C inputs allow for a DisplayPort™ Alt Mode video connection to laptops that do not feature an HDMI connection. The USB-C connectors also pass USB 2.0 data back and forth from the host PC and other DM NVX or DM NUX endpoints.

eARC Support

The HDMI output of the DM‑NVX‑385 supports Enhanced Audio Return Channel (eARC) connectivity, enabling audio to be extracted from a connected display and transmitted over the network as a multichannel BTS audio-over-IP stream. Extracting audio from the display via the eARC connection means only a single cable is required for A/V input and audio output. This also makes local audio content from the display (such as smart TV streaming applications) available to an AoIP audio distribution system.

The secondary HDMI input supports eARC as an audio output to pass content from a multichannel AoIP stream to the HDMI output of a connected AVR. The BTS multichannel AoIP stream generated by the DM NVX endpoint is also compatible with the DM‑NAX‑XSP (sold separately) for zones where video transmission is not required.

Real-Time 4K60 Video Distribution

DM NVX technology ensures real-time, full‑motion 4K60 and 5K video performance for the presentation of multimedia, videoconferencing, and live camera images. Interactive functions such as gameplay and using a mouse are fluid and natural. Line‑synchronized outputs ensure synchronization of content across multiple displays for applications such as digital signage and video walls. Variable Multicast TTL (Time To Live) enables traversing multiple network routers.

Support for 5K Resolutions

The DM-NVX-385 includes support for 5K Ultra-Wide 5120 × 2160 and 5K Super-Wide 5120 × 1440 video resolutions, 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-385 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 Ultra-Wide 4:4:4.

H.264 Streaming

H.264 encoding is supported on the DM‑NVX‑385 while in transmitter mode via an additional network stream. 1080p H.264 video can be distributed from one DM NVX device to multiple network decoders at up to 10-bit 4:2:2 color-depth and chroma subsampling. This enables streaming video directly from a DM NVX device to Crestron touch screens or digital graphics engines, or a broad range of third-party H.264-enabled devices.

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-385 is configurable to operate as either a network AV encoder or decoder. As an encoder, the connected media source can be transmitted over the network to one or many decoders. As a decoder, the device feeds the received signal to a connected display device, and can quickly switch between multiple encoder feeds. 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 5K Scaler

Whether configured as an encoder or decoder, 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.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.

7.1 Surround Sound Audio with Downmixing

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. The DM-NVX-385 can decode the incoming multichannel surround sound signal from the network or an HDMI input and then downmix that signal to stereo. The stereo downmix signal is automatically routed to the analog output5, while the HDMI output can be configured to output either stereo or multichannel signals. As an encoder, the DM-NVX-385 distributes both stereo and multichannel signals simultaneously over the network, allowing either signal to be selected at any decoder on the network.

Audio Embedding and De-embedding

AES67 support via native integration of Crestron DM NAX® Audio-over-IP technology allows the selected audio source to be transmitted as a 2-channel AES67 source. Another AES67 2-channel audio stream can be received from a Crestron DM NAX device or other AES67 capable device simultaneously 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.

An unbalanced stereo analog audio port is also included, which can be configured as either an input or output.5

Copper or Fiber Ethernet Connectivity

The DM-NVX-385 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. 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.2

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 ports are provided on the DM-NVX-385, 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.8

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

Streamlined Management Using DM NVX Director® Virtual Switching Appliances

Use of a DM NVX Director® virtual switching appliance (DM‑NVX‑DIR‑80, DM‑NVX‑DIR‑160, DM‑NVX‑DIR‑ENT, or DM‑NVX‑DIR2) streamlines the configuration and control process. A DM NVX Director appliance provides a central point of management and enables the creation of multiple virtual matrix switchers through one easy-to-use web-based portal.

Crestron XiO Cloud® Service Support

The DM-NVX-385 is compatible with the Crestron XiO Cloud® service for remote provisioning, monitoring, and managing. This service enables installers and IT managers to deploy and manage thousands of devices simultaneously. Refer to crestron.com/xiocloud for more information.

Low-Profile Installation

The DM-NVX-385 mounts conveniently to a flat surface or rack rail, and fits easily behind a flat panel display, above a ceiling-mounted projector, beneath a tabletop, or inside a lectern, AV cart, or equipment cabinet. Power is provided using POE++ or the optional Crestron PW‑2420RU power pack (sold separately).7

1. 5K performance and HDR support require the use of HDMI cables and couplers with a minimum TMDS bandwidth of 18 Gbps. If 4K60 4:2:0 or 4K30 4:4:4 performance is acceptable, cables and couplers with a minimum bandwidth of 10.2 Gbps may be used. Bandwidth loss is cumulative; therefore, performance may be reduced when inserting multiple cables and couplers inline.

2. The minimum cable required for DM NVX over 1000BASE-T Ethernet (copper) is unshielded CAT5e. All Ethernet ports on the DM-NVX-385 are for connection to an Ethernet network or device. The Ethernet ports cannot be connected to the DM® ports of other Crestron DigitalMedia™ devices.

3. Use of the SFP port requires the purchase of a Crestron SFP-1G Series transceiver module (sold separately). All Ethernet ports on the DM-NVX-385 are for connection to an Ethernet network or device. The Ethernet ports cannot be connected to the DM® ports of other Crestron DigitalMedia™ devices.

4. When the DM-NVX-385 is in encoder mode, the HDMI output resolution is matched to the resolution of the encoded source.

5. The analog audio port can function as either an input or output, but not both.

6. Combining audio from one encoder with video from another encoder is possible using the secondary 2-channel audio stream only. Multichannel audio from one encoder cannot be combined with video from another encoder.

7. Refer to the "Power" section for powering options.

8. The DM-NVX-385 can accept a USB device or a USB host device connection, not both simultaneously. Crestron DM NVX products are engineered to deliver maximum compatibility with the widest possible range of USB products. Crestron does not guarantee that all USB products are compatible with DM NVX products. Consult the DM NVX AV-over-IP System Design Guide for USB bandwidth considerations.

9. The minimum bit rate for 4K60 video is 350 Mbps. A bit rate below 350 Mbps may display a black screen.

10. In encoder mode, the stream type of the DM-NVX-385 must be set by using the web interface or a control system. The default setting is Pixel Perfect Processing for interoperability with DM NVX 4K60 4:4:4 decoders. For interoperability with a DM-NVX-D10, DM-NVX-D20, or DM-NVX-D200 decoder, the stream type of the DM-NVX-385 encoder must be set to DM-NVX-D10/D20 Series. In addition, the resolution of the encoder must be set so that it does not exceed the maximum resolution of the DM-NVX-D10, DM-NVX-D20, or DM-NVX-D200 decoder. In decoder mode, the proper stream type of the DM-NVX-385 is automatically used. For interoperability with DM NVX 4K60 4:4:4 encoders, Pixel Perfect Processing is automatically used as the stream type of the DM-NVX-385 decoder. For interoperability with DM-NVX-E10/E20 Series encoders, DM-NVX-D10/D20 Series is automatically used as the stream type of the DM-NVX-385 decoder.

11. 3D formats are not supported.

12. HDMI connections require an appropriate adapter or interface cable to accommodate a DVI or Dual-Mode DisplayPort signal. CBL-HD-DVI interface cables are available separately.

13. USB-C connections require USB-C cables that support DisplayPort Alt Mode video in order to pass video signal. Not all USB-C cables can support DisplayPort Alt Mode video.

14. When PoE++ is used to power the DM-NVX-385, a maximum of 500mA is available to power both the USB TO DEVICE and USB HID ports. To prevent possible instability issues, it is recommended that a PW-2420RU power pack (sold separately) be used.

15. In order for Ethernet port 1 to receive PoE++, the port requires connection to a PoE++ compliant Ethernet switch or other equipment that has a PoE++ PSE port. Cabling that connects to a PoE++ PSE port is designed for intrabuilding use only.
