Crestron DM-NVX-E30 4K60 4:4:4 HDR Network AV Encoder

Product Type: AV Over IP

Brand: Crestron


A reliable, high-performance AV over IP encoder that transports 4K60 4:4:4 video over standard Gigabit Ethernet with no perceptible latency or loss of quality. Supports HDR10 and HDCP 2.2. Provides a secure 4K signal routing solution for enterprise and campus-wide content distribution applications.

The Crestron® DM-NVX-E30 is a compact AV over IP encoder designed to function as a transmitter. Featuring secure web‑based control and management, an HDMI® input, an analog audio output, and copper LAN connectivity with PoE+ support, the DM-NVX-E30 offers a low‑cost encoder solution for a DM NVX network AV installation of any size.

Real‑Time 4K60 Video Distribution

Engineered for demanding conference room and classroom applications, DM NVX technology ensures real‑time, full‑motion 4K60 video performance for the presentation of multimedia, videoconferencing, and live camera images. Interactive functions such as gameplay and the use of a mouse are fluid and natural.

A DM NVX system is engineered for stability and ultimate reliability. Line‑synchronized outputs ensure perfect synchronization of content across multiple displays for applications such as digital signage. Variable Multicast TTL (Time To Live) enables traversing multiple network routers for optimal flexibility.

Pixel Perfect Processing Technology

A DM NVX system incorporates Pixel Perfect Processing technology, which provides flawless video transport in all applications. The DM-NVX-E30 can encode a video signal to achieve imperceptible end‑to‑end latency of less than 1 frame. The image quality of the source is maintained across a 1‑Gigabit network at any resolution up to 4K60 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 Functionality

The DM-NVX-E30 is a basic encoder with one HDMI input that allows a laptop computer, camera, or other media source to be connected via an HDMI cable and then transmitted over the network to one or many decoders. Compatible with DM NVX products that can function as decoders, the DM-NVX-E30 can be used in any DM NVX network AV design.

Image Preview

Image preview provides still images (thumbnails) that show the current video being received by an input of a DM NVX encoder. Still images are shown at one frame per second. Image preview supports the maximum resolution of the source and scales the image, while maintaining the aspect ratio. Images can be previewed in the DM NVX web interface and accessed remotely using a web browser. The images can also be previewed on a Crestron touch screen or third-party interface.

Adaptive Bit Rate

Adaptive bit rate can be enabled or disabled using the web interface or a control system. Adaptive bit rate enables the encoder to automatically set the bit rate required for the input resolution of the stream; for example, the adaptive bit rate for a common resolution such as 1920x1080p@60Hz (1080p60) is automatically set to 400 Mbps. Adaptive bit rate makes better use of the available bandwidth.

Analog Audio De-embedding

The analog audio output provides a stereo line‑level signal to feed a local sound system or sound bar. The output volume is adjustable via a control system or web browser.

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.

AES67 Audio Embedding or De-Embedding

AES67 support allows the HDMI source to be transmitted as a 2-channel AES67 stream while another 2‑channel AES67 audio stream is received from a Crestron DSP or other third-party device. The received AES67 audio stream can be output via the analog audio output.

Copper Ethernet Connectivity

The DM-NVX-E30 includes one RJ-45 1000BASE‑T Ethernet port. The port is PoE+ compliant, allowing the device to be powered via a PoE+ Ethernet switch.

Device Control

The DM-NVX-E30 includes built‑in COM (RS‑232) and IR ports for control of source devices under the management of a control system. Additional control capability is provided by CEC (Consumer Electronics Control) over the HDMI connection. Under the management of a control system, the DM-NVX-E30 can control a source device via CEC, potentially eliminating the need for dedicated serial cables or IR emitters.

Web‑Based Setup

Setup of the DM-NVX-E30 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.

Streamlined Management Using DM NVX Director Virtual Switching Appliances

For applications that are small to moderate in size, a network of DM NVX endpoints can be configured and controlled with the use of a control system. For larger enterprise and campus‑wide signal routing applications, adding a DM NVX Director virtual switching appliance (DM-NVX-DIR-80, DM-NVX-DIR-160, or DM-NVX-DIR-ENT) enhances and streamlines the entire 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-E30 is compatible with the Crestron XiO Cloud service, which is a platform for remotely provisioning, monitoring, and managing Crestron devices across an enterprise or an entire client base. The service enables installers and IT managers to deploy and manage thousands of devices in the amount of time it previously took to manage a single device. 

Low‑Profile Installation

The DM-NVX-E30 mounts conveniently to a flat surface or rack rail and fits easily beneath a tabletop or inside a lectern, AV cart, or equipment cabinet. All connectors and LED indicators are positioned on the front and rear of the device, offering optimal access and visibility for a clean, serviceable installation. Power is provided via PoE+ or an optional power pack (sold separately).
