Line‑synchronized outputs ensure perfect 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 for optimal flexibility.

        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‑352C can encode or decode 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 or Decoder Functionality
        The DM‑NVX‑352C is configurable to operate as either a network AV encoder or decoder:

        • As an encoder, the DM‑NVX‑352C allows the HDMI signal of the output of a switcher, computer, AirMedia® gateway, or other media source to be transmitted over the network to one or many decoders.1
        • As a decoder, the DM‑NVX‑352C receives the signal from a DM NVX encoder and feeds it to the input of a switcher or display device via the HDMI output. The decoder can quickly and easily switch between multiple encoders on the network alongside locally connected HDMI sources.1

        The DM‑NVX‑352C provides a versatile, cost‑effective solution for applications that require encoder and decoder operating modes in a single card. The operating mode can be reconfigured dynamically in less than 1 minute via a control system or web browser or via the DMF‑CI‑8 front panel.

        Auto-Switching HDMI® Inputs
        The DM‑NVX‑352C includes two HDMI inputs. Switching between the two inputs can be performed automatically using auto‑switching mode, programmatically via a control system, manually via the DMF‑CI‑8 front panel, or through a computer using a web browser.1

        HDMI Output with 4K60 4:4:4 Scaler
        When the DM‑NVX‑352C 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‑352C 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.

        Dynamic Text Overlay
        The DM-NVX-352C enables the display of dynamic text, providing a means to label the video source or to display special instructions, schedules, announcements, alerts, and other messaging.

        Image Preview
        Image preview provides still images (thumbnails) that show the current video being received by an input of a DM NVX encoder or displayed by an output of a DM NVX decoder. Still images are shown at 1 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.

        Background Image for On-Screen Display
        When the DM-NVX-352C is configured as a decoder, an image can be uploaded to the device for use as a background image on a display whenever active video content is not being displayed. Supported image file types are .jpeg, .jpg, and .png. The supported maximum resolution of an image is 3840x2160 pixels. Up to 20 image files can be uploaded for a total storage capacity of up to 100 MB.

        Test Pattern Generator
        When the DM-NVX-352C is configured as an encoder, the built-in test pattern generator can be used during setup to ensure that video streaming is functional. The test pattern generator can also be used as a tool for the adjustment, calibration, and alignment of displays, projectors, and video walls. The DM NVX encoder can send the test pattern to any routed DM NVX decoder.

        Fixed, Adaptive, or Variable Bit Rate
        In DM NVX encoder mode, the bit rate of a stream can be set to fixed, adaptive, or variable:

        • A fixed bit rate, also referred to as Constant Bit Rate (CBR), is user specified and can be set to a value ranging from 200 Mbps to 950 Mbps.5
        • Adaptive bit rate (ABR) enables the encoder to automatically set a fixed bit rate based on the input resolution of the stream. For example, the adaptive bit rate for a common resolution such as 1920x1080p@60Hz (1080p60) would automatically be set to 400 Mbps. Adaptive bit rate makes better use of the available bandwidth than a user-specified fixed bit rate.
        • Variable bit rate (VBR) enables the encoder to automatically vary the bit rate based on the content and input resolution of the stream. The bit rate can vary from less than 150 Mbps to a maximum of 750 Mbps. A variable bit rate results in the use of less bandwidth to produce the same image quality as a user-specified fixed bit rate or an adaptive bit rate.

        The web interface or a control system can be used to set a fixed bit rate or to enable adaptive or variable bit rate functionality.

        Analog Audio Embedding or De‑embedding
        A balanced 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 either 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 analog audio switcher. The output volume is adjustable via a control system or web browser.6

        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‑352C can 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.

        NOTE: The DSP of the DM-NVX-352C is compatible with Dolby Atmos audio using True HD or Dolby Digital Plus audio formats.

        Dante® or AES67 Audio Embedding and De‑embedding
        Dante and AES67 support enables the selected audio source to be transmitted as a 2‑channel Dante or AES67 audio stream while another 2‑channel Dante or AES67 audio stream is received from a Crestron DSP or other third‑party device and combined with the video signal.

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

        NOTE: A Dante or  AES67 audio stream that is received by a DM NVX endpoint cannot be transmitted from that endpoint.

        Breakaway Audio
        A DM NVX decoder can select and combine separate video and audio signals from two different inputs—even two different encoders.7

        Copper and Fiber Ethernet Connectivity
        The DM‑NVX‑352C includes one RJ-45 1000BASE-T LAN port (Ethernet port 1) and one SFP port (Ethernet port 2). 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

        Ethernet port 1 or 2 can be used to transport video over a Gigabit Ethernet network. Ethernet port 1 can also be used to provide a network connection for an AirMedia gateway, display device, or other local device. In addition, the port can 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, Doc. 7977.

        Network Port Selection
        Network port selection enables network traffic to be managed and segregated based on traffic type. Internal VLANs are used to route different traffic types to specific external Ethernet ports, which can then be assigned to the various traffic types. AES67 audio can be separated from the primary video and control network resulting in a dedicated audio network.

        Automatic Point-to-Point Connectivity
        Point-to-point connectivity enables a DM NVX 4K60 4:4:4 encoder to be connected directly to a DM NVX 4K60 4:4:4 decoder to stream video, audio, and USB signals. Rather than being connected to a Gigabit Ethernet network, a 1000BASE-T Ethernet port of an encoder is connected directly to a 1000BASE-T port of a decoder. By default, point-to-point mode is enabled and can be disabled if desired.

        When point-to-point mode is enabled and a direct connection between an encoder and decoder is automatically detected, no additional configuration is required for the encoder or decoder to operate in point-to-point mode; however, the operating mode of a DM-NVX-352C card must be configured correctly. If the card is to function as an encoder, the operating mode of the card must be configured as an encoder. If the card is to function as a decoder, the operating mode must be configured as a decoder. In addition, a control system is required for CEC (Consumer Electronics Control)..

        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 HOST and DEVICE ports are provided on the DM‑NVX‑352C, 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 HOST port of up to seven remote DM NVX endpoints to the DEVICE port of a single local DM NVX endpoint. Layer 2 also supports Crestron USB over Ethernet Network extenders, which consist of the DM-NUX-L2, DM-NUX-R2, DM-NUX-L2-1G, DM-NUX-R2-1G, and legacy models (USB‑NX2‑LOCAL-1G, USB‑NX2‑REMOTE-1GUSB‑EXT‑DM‑LOCAL, and USB‑EXT‑DM‑REMOTE). The USB extenders can be used in locations that do not include DM NVX endpoints. USB signals can be routed between DM NVX endpoints and USB extenders under the management of a control system.9

        USB 2.0 Layer 3 data transport supports USB signal extension in DM NVX point-to-point applications across VLANs. DM NUX, USB NX2, and USB EXT DM devices do not support Layer 3.

        CEC Device Control
        The DM‑NVX‑352C provides a gateway for controlling devices via CEC over the HDMI connections. Under the management of a control system, the DM‑NVX‑352C can control display devices and other equipment via CEC, potentially eliminating the need for any dedicated serial cables or IR emitters.

        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‑352C is accomplished by using a web browser. Full control and monitoring of the card 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.

        High‑Density, Card‑Based Solution
        The DM‑NVX‑352C is designed for installation into a DMF‑CI‑8 card chassis, providing a scalable high‑density solution for applications requiring multiple encoders and decoders in one equipment rack.

        1. 4K60 4:4:4 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‑352C are for connection to an Ethernet network or device; they cannot be connected to the DM® ports of other Crestron devices.

          A nonblocking network is required for DM NVX 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‑352C are for connection to an Ethernet network or device. The Ethernet ports cannot be connected to the DM ports of other Crestron devices.
        4. When the DM‑NVX‑352C is in encoder mode, the HDMI output resolution is matched to the resolution of the encoded source.
        5. The minimum bit rate for 4K60 video is 350 Mbps. A bit rate below 350 Mbps may display a black screen.
        6. The analog audio port can function as an input or output—not both. Analog audio output is only functional when the DM‑NVX‑352C is receiving a 2‑channel stereo input signal. A 2‑channel downmix signal from a multichannel surround sound source requires the use of a Crestron DM‑NVX‑351 or DM‑NVX‑351C.
        7. Audio from one onboard HDMI input cannot be combined with video from the other onboard HDMI input. Combining audio from one encoder with video from another encoder is possible using the 2‑channel AES67 or Dante audio stream only. Multichannel audio from one encoder cannot be combined with video from another encoder.
        8. The DM‑NVX‑352C 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. Consult the DM NVX AV-over-IP System Design Guide, Doc. 7977, for USB bandwidth considerations.
        9. The DM‑NVX‑352C is not compatible with the USB HID signal extender technology found in other Crestron DM products.
        10. In encoder mode, the stream type of the DM-NVX-352C 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-352C encoder must be set to DM-NVX-D10/D20/D200 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-352C 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-352C decoder. For interoperability with DM-NVX-E10/E20 Series encoders, DM-NVX-E10/E20 Series is automatically used as the stream type of the DM-NVX-352C decoder.
        11. As an encoder, the DM‑NVX‑352C transmits audio via the 2‑channel  AES67 or Dante stream when it receives a 2‑channel stereo input signal via the HDMI or analog inputs.
        12. 3D formats are not supported.
        13. 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.

        1. 4K60 4:4:4 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‑352C are for connection to an Ethernet network or device; they cannot be connected to the DM® ports of other Crestron devices.

          A nonblocking network is required for DM NVX 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‑352C are for connection to an Ethernet network or device. The Ethernet ports cannot be connected to the DM ports of other Crestron devices.
        4. When the DM‑NVX‑352C is in encoder mode, the HDMI output resolution is matched to the resolution of the encoded source.
        5. The minimum bit rate for 4K60 video is 350 Mbps. A bit rate below 350 Mbps may display a black screen.
        6. The analog audio port can function as an input or output—not both. Analog audio output is only functional when the DM‑NVX‑352C is receiving a 2‑channel stereo input signal. A 2‑channel downmix signal from a multichannel surround sound source requires the use of a Crestron DM‑NVX‑351 or DM‑NVX‑351C.
        7. Audio from one onboard HDMI input cannot be combined with video from the other onboard HDMI input. Combining audio from one encoder with video from another encoder is possible using the 2‑channel AES67 or Dante audio stream only. Multichannel audio from one encoder cannot be combined with video from another encoder.
        8. The DM‑NVX‑352C 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. Consult the DM NVX AV-over-IP System Design Guide, Doc. 7977, for USB bandwidth considerations.
        9. The DM‑NVX‑352C is not compatible with the USB HID signal extender technology found in other Crestron DM products.
        10. In encoder mode, the stream type of the DM-NVX-352C 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-352C encoder must be set to DM-NVX-D10/D20/D200 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-352C 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-352C decoder. For interoperability with DM-NVX-E10/E20 Series encoders, DM-NVX-E10/E20 Series is automatically used as the stream type of the DM-NVX-352C decoder.
        11. As an encoder, the DM‑NVX‑352C transmits audio via the 2‑channel  AES67 or Dante stream when it receives a 2‑channel stereo input signal via the HDMI or analog inputs.
        12. 3D formats are not supported.
        13. 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.
