Features

Versatile 4x4 HDMI Matrix Switching

The LKV844 connects up to four HDMI sources and distributes their signals to four remote displays. Independent input selection enables flexible routing of video sources to connected display outputs.

4K Ultra HD at 60Hz

Supporting resolutions up to 3840 x 2160 at 60Hz, the extender delivers detailed UHD video for compatible monitors, televisions and projectors. HDR10 compatibility provides enhanced visual performance on supported equipment.

Long-Distance 70m HDMI Extension

The system extends HDMI signals up to 70m using CAT6, CAT6A or CAT7 network cables, providing flexible installation options for meeting rooms, education facilities and digital signage environments.

Four Local HDMI Loop-Outs

Four HDMI loop-out ports allow local displays to be connected directly to the transmitter, while four remote receiver units extend signals to additional displays. This enables up to four local and four remote display connections.

Power over Cable Technology

Power over Cable allows the transmitter to supply power to connected receivers through the network cables, eliminating the need for separate receiver power adapters during normal installation.

Multiple Control Options

The matrix supports front-panel button control, infrared remote control, RS-232 and Ethernet control, providing convenient management of video routing and system settings.

IR Passback and EDID Management

Unidirectional IR passback enables control of compatible source equipment from remote locations. EDID management helps maintain compatibility between connected HDMI sources and displays.

Digital Audio Extraction

Each receiver supports S/PDIF digital audio extraction, allowing compatible external audio equipment to receive audio signals separately from HDMI video output.

Durable Professional Design

The metal enclosure provides durability for professional AV installations. Integrated ESD, surge and lightning protection supports reliable operation in suitable environments.
