Provides eight HDMI® and Dante™ outputs with built-in 4K scaling for any DigitalMedia™ Switcher with modular output blade slots. Enables fully-digital integration between DigitalMedia and Avia™ DSP products.

The DMB-4K-O-HD-DNT is an output blade designed for use with any blade-based Crestron® DigitalMedia™ Switcher. It provides eight independent HDMI® outputs with complementary analog audio outputs and Dante™ audio networking. The HDMI outputs are each capable of handling Full HD 1080p, Ultra HD, 2K, and 4K video signals with support for HDCP 2.2, Deep Color, and high-bitrate 7.1 audio. Built-in 4K scaling enables the devices connected to each HDMI output to handle any video resolution from NTSC 480i to DCI 4K. DVI signals are also supported using HDMI-to-DVI adapters or interface cables.

Support for Dante audio networking allows for routing of stereo audio output signals to other Dante enabled equipment over the local area network. The analog audio outputs are enabled using the optional Analog Audio Breakout Box (model AUD-BOB-1602), which provides support for balanced or unbalanced stereo line-level signals.

4K/60 Scalers

  • An independent, high-performance 4K scaler is provided at each output to ensure that input sources of any resolution or frame rate can be routed and displayed reliably on virtually any display device without compromising the original input signal. As part of a DM® switcher with many outputs, this allows any video or computer source to be viewed simultaneously on multiple disparate displays, scaling the signal up or down to match the native resolution of each display.
  • No matter what source is selected, or where it’s routed, the DMB-4K-O-HD-DNT helps to ensure an optimal image on every screen. It can take any input resolution from standard definition NTSC 480i to ultra high-definition DCI 4K, and scale it beautifully to any output resolution up to DCI 4K (4096 x 2160 @ 60 Hz). Interlaced sources are converted to progressive scan using motion-adaptive deinterlacing. Intelligent frame rate conversion enables support for 24p and PAL format sources. 3D signals are converted to 2D. Fully automatic operation eliminates any complicated setup by utilizing the displays’ EDID to configure each scaler.

Video Wall Processing

  • The DMB-4K-O-HD-DNT has another trick up its sleeve, providing zoom capability and bezel compensation on each output to display just a portion of the source image. Using this feature, up to eight output cards may be combined to provide processing for a video wall composed of up to 64 individual displays. Video wall configurations up to eight wide by up to eight high are supported.

Analog Audio De-Embedding

  • Each HDMI output on the DMB-4K-O-HD-DNT is accompanied by a balanced analog audio output, allowing stereo audio signals to be extracted from the digital output and fed to a sound system. The analog audio outputs are enabled using the optional Analog Audio Breakout Box (model AUD-BOB-1602).

Dante™ Audio Networking

  • Dante networking enables streamlined integration with Crestron Avia™ DSP products and other Dante enabled audio processors, amplifiers, mixers, and switchers. Dante allows stereo audio signals from any or all of the blade’s outputs to be routed to such equipment over an Ethernet network. Send/return loop capability is also supported, allowing audio from any input source to be externally processed, mixed, or switched via Dante, and then re-embedded with the video signal at any of the HDMI outputs. The Dante network interface is provided via the DM switcher’s LAN port, supporting up to 120 simultaneous stereo input and output signals.

CEC Embedded Device Control

  • DigitalMedia offers an alternative to conventional RS-232 and IR display control by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. Through its connection to a control system (via the DM switcher), the DMB-4K-O-HD-DNT provides a gateway for controlling display devices right through their HDMI connections, potentially eliminating the need for any dedicated control wires or IR emitters.
