The HD-MD402 is a 4K60 4:2:0 AV switcher that provides a cost-effective solution for professional AV applications. The HD-MD402 provides four HDMI® inputs one mirrored HDMI and DM Lite® output and one independent DM Lite output. The DM Lite outputs extend HDMI signals over a CATx (CAT5e or higher) twisted pair cable. For HD 1080p WUXGA and 2K signals a CATx cable length of up to 230 ft (70 m) is supported. For UHD and 4K signals a CATx cable length of up to 130 ft (40 m) is supported.

4K to 1080p Downscaling
The mirrored HDMI and DM Lite output and the independent DM Lite output each have a built-in scaler for downscaling 4K to 1080p signals. Input resolutions are automatically downscaled to 1080p regardless of the resolution capabilities of the display device. If desired downscaling can be disabled. Input resolutions up to 4K60 4:2:0 are supported.

HDMI Audio De-embedding
Embedded HDMI 2-channel LPCM audio can be extracted from the selected HDMI input and transmitted to the AUX stereo audio output. Mute control is configurable for the mirrored HDMI and DM Lite output the independent DM Lite output and the AUX audio output independently. Volume control is only configurable for the AUX audio output.

USB Power Port
A USB power port is included on the HD-MD402 to power USB powered devices (500mA maximum).

NOTE: No USB data is passed through the USB power port. The port cannot be used to extend USB data video or audio signals.

Automatic Display Power
The COM (RS-232) port can enable the display device to be turned on or off automatically without the use of a control system. The port also enables full programmable control of any device with the use of a control system. (The COM port can be used for transmission of data only. No data will be received though the COM port.) 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.

Built-In Web Interface
Configuration of the HD-MD402 can be accomplished by using the built-in web interface. The configuration of a single unit can be downloaded to a computer or mobile device and then uploaded to multiple HD-MD402 units to simplify system installation.

.AV Framework™ Technology Support (Coming Soon)
In addition to a built-in web interface and control system programming built-in .AV Framework technology of a Crestron control system can be used to configure and control the HD-MD402.

Surface-Mountable Design
The HD-MD402 can be installed using the included mounting hardware. The device can be mounted onto a wall or other flat surface.
