Models & Accessories

The DM‑RMC‑4KZ‑SCALER‑C provides an advanced one‑box interface solution for a single display device as part of a complete Crestron® DigitalMedia™ system. Functioning as a DM 8G+® receiver, 4K60 4:4:4 HDR video scaler, and control interface, the DM‑RMC‑4KZ‑SCALER‑C provides DM 8G+ and HDMI® inputs, an HDMI output, and an analog audio output.^{1, 2, 3} RS‑232, IR, Ethernet, and relay control ports are also provided.

4K60 4:4:4 and HDR Support
The DM‑RMC‑4KZ‑SCALER‑C incorporates DM 4KZ technology, which uses VESA® Display Stream Compression (DSC) to handle the extreme bandwidth requirement of resolutions beyond 4K30 4:4:4 and 4K60 4:2:0. DSC is a lightweight, line‑based 2:1 compression standard that delivers visually lossless performance for 4K60 4:4:4 and HDR signals.⁴ DSC is applied only to 4K60 4:4:4 and HDR input signals. All other signals are transported uncompressed.

An existing 4K DigitalMedia system can be upgraded to handle 4K60 4:4:4 and HDR video with the installation of DM 4KZ cards, transmitters, and receivers. The upgrade can be accomplished without the need to replace wiring or switchers. The DM‑RMC‑4KZ‑SCALER‑C can replace a DM‑RMC‑4K‑SCALER‑C in an existing installation (additional programming may be required).

DM 8G+ Technology
Engineered for ultra high‑bandwidth and ultimate scalability, Crestron® DM 8G+ technology transports high‑definition video, audio, power, Ethernet, and control signals over twisted pair copper wire. Uncompressed Full HD 1080p, WUXGA, and 2K signals are supported at distances up to 330 feet (100 m) using Crestron DM® Ultra Cable, Crestron DM 8G® Cable, or third‑party CAT5e (or higher). Higher resolution signals up to UHD and 4K are supported at distances up to 330 feet (100 m) using DM Ultra Cable, 230 feet (70 m) using DM 8G Cable, or 165 feet (50 m) using third-party CAT5e (or higher).⁵

Compatible with the HDBaseT Standard
DM 8G+ technology is designed using HDBaseT Alliance specifications, ensuring interoperability with other HDBaseT® certified products. Via the DM 8G+ input, the DM‑RMC‑4KZ‑SCALER‑C can be connected directly to an HDBaseT compliant source without requiring a DM transmitter.

Multimedia Display Interface
The DM‑RMC‑4KZ‑SCALER‑C provides simple switching between a DM input and an HDMI input. An input can be selected manually by using the INPUT SELECT push button on the device, programmatically through a control system, or automatically by connecting a source to an input.

A single HDMI output port is provided for connection to a display device. The HDMI output can also handle DVI signals using an appropriate adapter or interface cable.²

A single CAT5e (or higher) cable connects the DM‑RMC‑4KZ‑SCALER‑C to a DM switcher or transmitter or to an HDBaseT source, transporting video, audio, control, networking, and power signals through one simple RJ-45 connection. Multiple DM‑RMC‑4KZ‑SCALER‑C devices can be installed to handle each display in a multiroom distribution system—all fed from a central DM switcher. Alternatively, a single DM‑RMC‑4KZ‑SCALER‑C can be fed straight from a DM 8G+ or HDBaseT transmitter, providing a simple solution for extending a computer or AV signal to a single display.

4K60 4:4:4 Scaler
The HDMI output of the DM‑RMC‑4KZ‑SCALER‑C feeds the decoded signal to the local display device. 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.

Interlaced sources are converted to progressive scan using motion‑adaptive deinterlacing. Intelligent frame rate conversion enables support for 24p and PAL format sources. Fully automatic operation eliminates any complicated setup by using the EDID (Extended Display Identification Data) of the display to configure the scaler.

Video Wall Processing
The DM‑RMC‑4KZ‑SCALER‑C provides zoom capability and bezel compensation on the HDMI output to display only a portion of the source image. Multiple DM‑RMC‑4KZ‑SCALER‑C devices can be combined to configure a video wall composed of up to 64 individual displays. Configurations of up to 8 wide by 8 high are supported, requiring a separate DM‑RMC‑4KZ‑SCALER‑C for each display and one or more DM switchers with sufficient DM 8G+ outputs.

Audio De‑embedding
The DM‑RMC‑4KZ‑SCALER‑C is equipped with a balanced/unbalanced analog audio output, allowing stereo audio signals to be extracted from the digital stream and fed to a local amplifier, sound bar, or a pair of powered speakers.³ The output volume is adjustable via a control system using a keypad, touch screen, handheld remote, or mobile device.

LAN Connectivity
In addition to high‑definition AV and control, a DigitalMedia system integrates high‑speed Ethernet networking for a total signal distribution solution. The DM‑RMC‑4KZ‑SCALER‑C includes a 100 Mbps Ethernet port, which can be used to provide a convenient LAN connection for a local network device.

Embedded Device Control
The DM‑RMC‑4KZ‑SCALER‑C includes built‑in RS‑232, IR, and Ethernet control ports to enable programmable control of the connected display device via a control system. When connected to a control system, the DM‑RMC‑4KZ‑SCALER‑C also provides a gateway for controlling the display device through CEC (Consumer Electronics Control) over the HDMI output, potentially eliminating the need for dedicated control wires or IR emitters. The DM‑RMC‑4KZ‑SCALER‑C also supports CEC over the HDBaseT connection, enabling control of an HDBaseT source connected to the DM 8G+ input.

Two low‑voltage relay ports are also included on the DM‑RMC‑4KZ‑SCALER‑C for control of a projection screen or lift.

USB Signal Extension (Optional)
A DigitalMedia system allows for the routing of USB signals alongside video and audio. USB signal extension is enabled on the DM‑RMC‑4KZ‑SCALER‑C by adding a USB‑EXT‑DM USB over Ethernet Extender Module.⁶

Low‑Profile Installation
The DM‑RMC‑4KZ‑SCALER‑C mounts conveniently to a wall, ceiling, or other flat surface. The device fits easily behind a flat panel display or above a ceiling‑mounted projector. The unit can be powered by PoDM+, HDBaseT PoE+, or the optional PW-2412WU wall mount power pack (sold separately).^{7, 8}

All connectors and LED indicators are positioned on the sides, ensuring optimal access and visibility for a clean, serviceable installation. An array of indicators is provided for easy setup and troubleshooting.

Low‑profile surface-mount design

The HDMI input can accommodate a DVI or Dual-Mode DisplayPort signal using an appropriate adapter or interface cable. CBL-HD-DVI interface cables are available separately.
The HDMI output can accommodate a DVI signal using an appropriate adapter or interface cable. CBL-HD-DVI interface cables are available separately.
The analog stereo audio output is active only when the DM‑RMC‑4KZ‑SCALER‑C is receiving a 2-channel stereo signal. For applications using a multichannel surround sound source, use the DM-RMC-4K-SCALER-C-DSP, which provides a stereo downmix of the multichannel signal.
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 can be used. Bandwidth loss is cumulative; therefore, performance may be reduced when inserting multiple cables and couplers inline.
The maximum cable length for DigitalMedia 8G+ (DM 8G+) or HDBaseT transmission is dependent upon the type of cable and resolution of the video signal. Refer to the “Maximum Cable Lengths” table for a detailed overview. Crestron legacy cable models DM-CBL and DM-CBL-D support the same resolutions and cable lengths as CAT5e. Shielded cable and connectors are recommended to safeguard against unpredictable environmental electrical noise that may impact performance at resolutions above 1080p. Refer to the Crestron DigitalMedia System Design Guide for additional guidelines. DM 8G+ technology is compatible with the HDBaseT Alliance specifications for connecting to HDBaseT compliant equipment. All wire and cables are sold separately.
USB-EXT-DM USB over Ethernet Extender Modules are sold separately. Refer to the USB-EXT-DM-LOCAL and USB-EXT-DM-REMOTE specification sheets for more information.
In order for the DM-RMC-4KZ-SCALER-C to receive PoDM+ (Power over DigitalMedia+), the device must connect to a DM switcher or other equipment that has a PoDM+ PSE port. Wiring that connects to a PoDM+ PSE port is for intrabuilding use only.
In order for the DM-RMC-4KZ-SCALER-C to receive HDBaseT PoE+, the device must connect to equipment that has an HDBaseT PoE+ PSE port. Wiring that connects to an HDBaseT PoE+ PSE port is for intrabuilding use only.
Video wall processing requires a separate DM-RMC-4KZ-SCALER-C for each display.
