DigitalMedia™ NVX technology transports ultra high-definition 4K video
with 60 Hz frame rates and 4:4:4 color sampling over standard Gigabit
Ethernet. Support for HDR video (HDR10) and HDCP 2.2 ensures the
ultimate in picture quality and compatibility for all of today’s varied media
sources. Using standards-based Ethernet wiring and switches, DM® NVX
delivers a vastly scalable, high-performance solution for enterprise-wide
4K content distribution.[1]
The Crestron® DM-NVX-350 is a compact video encoder/decoder
designed to function as either a transmitter or receiver with the ability to
switch between the two modes programmatically via commands from a
Crestron control system. Featuring simple web-based control and
management, USB and KVM integration, and support for copper and fiber
LAN connectivity, the DM-NVX-350 offers a one-stop solution for any-sized
network AV installation.[2]
Real-Time 4K60 Video Distribution
Engineered for demanding conference room and classroom applications,
DM NVX ensures real-time, full-motion 4K60 video performance for the
presentation of multimedia, videoconferencing, and live camera images.
DM NVX employs high-quality JPEG 2000 encoding using a patent-pending
technique that overlaps scaling and encoding latencies, achieving an
| 800.237.2041
ultra-low end-to-end latency of 30 ms at 60 fps, so on-screen functions
such as mousing and game play are fluid and natural.
Encoder and Decoder in One
In a single compact device, the DM-NVX-350 is configurable to operate as
either a network AV encoder or decoder.
• As an encoder, it allows a laptop computer, camera, or other media
source to be connected via HDMI® and then transmitted over
the network.[1]
• As a decoder, it receives the signal from a DM NVX encoder and feeds it
to a display device via the HDMI output. It can quickly and easily switch
between multiple encoders on the network alongside locally-connected
HDMI sources.[1]
• The encoder/decoder mode can be switched on-the-fly via a control
system to provide a versatile, cost-effective presentation switching
solution using one integrated device.
2x1 HDMI® Auto-Switcher
The DM-NVX-350 includes two HDMI inputs. Switching between the
two inputs can be performed automatically using auto-switching mode,
manually using the onboard input select button, programmatically via a
Crestron control system, or through a computer using a web browser.
When used as a decoder mounted behind a typical conference room
display device, the HDMI inputs provide a convenient way to connect a
Crestron AirMedia® presentation gateway.[1]
HDMI Output
When configured as a decoder, the DM-NVX-350’s HDMI output feeds
the decoded signal to the local display device (or any other device with
an HDMI input). Its 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 used as an encoder, the HDMI output can be used to
feed a local display, confidence monitor, or audio system.[1,3]

USB and KVM Integration
For a complete signal management solution, DM NVX supports the
extension of USB signals, which may be switched and routed alongside
the AV signal or separately via the control system. USB 2.0 host and device
ports are provided on each DM-NVX-350 box, allowing a USB mouse,
keyboard, or other device to be connected at one box and routed to a
computer or other host at another box. KVM switch functionality is a
natural application for this feature, but all types of USB peripherals are
supported including whiteboards, touch screens, game controllers,
cameras, mobile devices, headsets, and flash drives.[4]
USB signals can also be routed to other locations where a DM NVX
box does not exist using Crestron USB over Ethernet Extender Modules
(USB-EXT-DM). USB signals can be freely routed between DM NVX and
USB-EXT-DM units over Ethernet under the management of a Crestron
control system.
7.1 Surround Sound Audio
DM NVX 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-350 has the
ability to receive both multichannel and 2-channel downmix signals from
a 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.
Analog Audio Embedding or De-embedding
A balanced stereo analog audio port is included, which may be configured
as either an input or output. As an input, it allows a stereo audio source to
be connected and combined with the video signal from either HDMI input
or the incoming network video stream. As an output, it can provide 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.[5]
Breakaway Audio
A DM NVX decoder may select and combine separate video and audio
signals from two different inputs, even two different encoders. There are
just two exceptions: A) signals may not be combined between the two
| 800.237.2041
onboard HDMI inputs, and B) combining signals from two separate
encoders is limited to 2-channel stereo audio.[6,7]
Text Overlay
The ability to display dynamic or fixed text on screen provides a means
to label the video source or display special instructions, schedules,
announcements, alerts, and other messaging.
Video Wall Processing
A video wall composed of up to 64 individual displays can be configured
using multiple DM-NVX-350 units. Each unit provides fully-adjustable zoom
capability and bezel compensation to accommodate a range of video wall
configurations and display types. One DM-NVX-350 is required per display,
supporting configurations of up to eight wide by up to eight high.
Copper or Fiber LAN Connectivity
The DM-NVX-350 includes two RJ45 1000Base-T LAN ports. Either port
may be used as the primary LAN connection, allowing the other to be used
to provide a network connection for the display, AirMedia gateway, or other
local device(s). These ports may also be used to daisy-chain multiple units
feeding a single-source video wall or individual displays all showing the
same video image. Port 1 is also capable of receiving power from a
Crestron power injector (DM-PSU-ULTRA-MIDSPAN).[8]
Connection to a fiber optic network is facilitated by inserting an appropriate
SFP transceiver module (Crestron SFP-1G series [2]) into the SFP port on the
DM-NVX-350. A selection of modules is offered to accommodate various
multimode and single-mode fiber types.
Enterprise-Grade Security
A secure AV network ensures its own reliability by protecting the integrity
of the content being delivered and the privacy of the personnel accessing
it. Employing advanced security features and protocols like 802.1x
authentication, Active Directory credential management, PKI certification,
AES encryption, TLS, SSH, and HTTPS, DM NVX delivers a true enterprisegrade network AV solution engineered to fulfill the demanding IT policies of
corporate, university, medical, military, and governmental clients. DM NVX
runs on a dedicated AV network, with fully-managed access to, or isolation
from, the customer’s LAN or the Internet.
DM-NVX-350 DM® 4K60 4:4:4 HDR Network AV Encoder/Decoder
Device Controller
The DM-NVX-350 includes built-in RS-232 and IR control ports for control
of the connected display, camera, and other devices under the management
of a control system. Additional control capability is afforded by harnessing
the CEC (Consumer Electronics Control) signal embedded in HDMI. Through
its Ethernet connection to the control system, the DM-NVX-350 provides a
gateway for controlling the display and source devices right through their
HDMI connections, potentially eliminating the need for any dedicated serial
cables or IR emitters.[9]
Web-Based Setup
Setup of the DM-NVX-350 is accomplished using a computer web browser.
Full control and monitoring of the device is enabled through integration
with a Crestron control system.
Low-Profile Installation
The DM-NVX-350 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. All
connections and LED indicators are positioned on the top and bottom,
offering optimal access and visibility for a clean, serviceable installation.
Power is provided using the included 100-240V universal power pack or an
optional power injector (Crestron DM-PSU-ULTRA-MIDSPAN).[8]

DM-NVX-350 DM® 4K60 4:4:4 HDR Network AV Encoder/Decoder
Available Models
1. 4K60 4:4:4 performance requires the use of HDMI cables with a minimum TMDS bandwidth
of 18 Gbps, such as Crestron model CBL-HD (20 ft / 6.1 m max. length). If 4K60 4:2:0 or
4K30 4:4:4 performance is acceptable, cables with a minimum bandwidth of 10.2 Gbps may
be used, such as Crestron models CBL-HD-LOCK or CBL-HD (any available length).
Performance may also be affected if an HDMI coupler is inserted in the HDMI signal path.
Crestron coupling products (MP-WP150, MP-WP152, MPI-WP150, or FTA-CP-HD-101) and
cable retractors (CBLR2-HD) all have a specified bandwidth of 10.2 Gbps, and thus do not
support 4K60 4:4:4. Please be aware that bandwidth loss is cumulative, so the combination of
multiple components inserted inline may reduce performance.
2. To add a fiber optic LAN port requires the purchase of a Crestron SFP-1G series SFP
transceiver module (sold separately). All LAN ports on the DM-NVX-350 are for connection to
an Ethernet based AV network or device; they cannot be connected to the “DM” ports of other
Crestron devices.
3. When in encoder mode, the HDMI output resolution is matched to the resolution of the
encoded source.
4. The DM-NVX-350 can be configured to accept the connection of a USB device or a USB host,
not both. 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. DM NVX is compatible with Crestron USB-EXT-DM
products, but is not compatible with the “USB HID only” signal extender technology found in
other Crestron DM products.
5. The analog audio port can function as an input or output, not both. Analog audio output is
only functional when the DM-NVX-350 is receiving a 2-channel stereo input signal. To derive
a 2-channel downmix signal from a multichannel surround sound source, please refer to the
Crestron DM-NVX-351 or DM-NVX-351C.
6. Audio from one onboard HDMI input may not be combined with video from the other onboard
HDMI input.
7. Combining audio from one encoder with video from another encoder utilizes the secondary
2-channel audio stream. Multichannel audio from one encoder cannot be combined with video
from another encoder.
8. The DM-NVX-350 is powerable using the 24V power pack (included) or a DM-PSU-ULTRAMIDSPAN (sold separately).
9. Device control via RS-232, IR, CEC, or Ethernet requires integration with a Crestron control
10. As an encoder, the DM-NVX-350 does not transmit audio via the secondary 2-channel stream
except when it is receiving a 2-channel stereo input signal via the HDMI or analog inputs.
11. 3D video input signals are automatically converted to 2D.
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.
