Crestron® 4K 4x1 Scaling Auto-Switcher and DM Lite® Extender over CATx Cable

Provides a cost-effective high-definition AV presentation solution for classrooms and meeting spaces. Consists of a transmitter (HD-TX-301-C-E) and receiver (HD-RX-4K-210-C-E) that enable AV switching, scaling, and signal extension over a single CATx cable for up to 230 ft (70 m). Provides auto-switching HDMI® and VGA inputs on the transmitter and an additional HDMI input on the receiver. 4K scaling HDMI output ensures a reliable, high-quality video image. Supports 4K60 4:2:0 video.

The Crestron® HD-MD-4K-400 provides a cost-effective multimedia presentation solution for classrooms and meeting spaces. Consisting of a transmitter (HD-TX-301-C-E) and receiver (HD-RX-4K-210-C-E), the HD-MD-4K-400 extends an HDMI® or VGA signal over a CATx (CAT5e or higher) twisted pair cable. For resolutions up to 2K, the maximum transmission distance is 230 ft (70 m). For higher resolutions up to 4K, the maximum transmission distance is 130 ft (40 m).

The transmitter provides two HDMI inputs and one VGA input with a complementary stereo analog audio input. The receiver provides an additional HDMI input that can be connected to a local AV source or to an optional Crestron media presentation wall plate (MP-WP152, sold separately).

Automatic Switching of Inputs

Automatic switching among the HDMI and VGA inputs on the transmitter and the HDMI input on the receiver can occur based on the last connected input or on the routing priority assigned to each input. Switching behavior is configurable using the web interface or programmable using a Crestron control system. In addition to automatic switching, input selection push buttons on the transmitter and receiver enable the desired input to be selected manually.

HDMI Output with 4K Scaler

A single HDMI output with a built-in scaler connects the receiver to a display or other device with an HDMI input. Input resolutions are automatically scaled to match the native resolution of the display device, resulting in optimal image quality. For applications requiring comprehensive EDID management, the web interface can be used to ensure that every input is displayed at its optimal resolution and format. Input resolutions up to 4K60 4:2:0 are supported.

Audio De-embedding

The analog audio output on the receiver enables the HD-MD-4K-400 to extract the stereo audio signal from digital sources to feed a sound bar, amplified speakers, or a separate sound system. The analog audio output is active only when the input is receiving a 2-channel stereo signal from the analog input or an HDMI input.

Device Control

Equipped with onboard control ports, the receiver can control various devices in a room. The COM (RS-232) port and CEC over the HDMI output can enable the display device to be turned on or off automatically without the use of a control system. With the use of a control system, the IR port can also control the display device. Two relay ports are provided for controlling a projection screen and other low-voltage contact closure activated equipment. Two Versiport I/O ports enable the integration of devices such as power sensors and motion detectors. An Ethernet port connection to a LAN also provides control by enabling use of the built-in web interface as well as connection to a control system.

.AV Framework™ Technology Support

In addition to a built-in web interface and control system programming, the built-in .AV Framework technology of the MPC3-201 and MPC3-302 control systems can be used to control the HD-RX-4K-210-C-E as a switcher.

Crestron XiO Cloud™ Service Support

The HD-MD-4K-400 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 transmitter and receiver can be placed on or attached to a flat surface. The transmitter can fit discreetly inside a presentation lectern or be attached to the underside of a table. The receiver can be mounted onto a wall behind a display or onto a ceiling above a projector. The devices can also be attached to a rack rail of an equipment cabinet.
