50-Metre 4K HDMI Extender

The Kanex Pro A/V Extender & Repeater transmits 4K video at 18 Gbps over a single cable run up to 50 metres. It consists of a transmitter unit and a receiver unit designed for professional audio-visual installations. The device extends HDMI signals without compression over long distances.

Installers needing long cable runs

This extender suits installers who must bridge 50 metres between a 4K source and a display. It is not for users who require distances beyond 50 metres or who need support for resolutions higher than 4K. Buyers needing wireless transmission or fibre-based extension should consider other solutions.

Transmitter and receiver included

The package provides one transmitter and one receiver so the link is ready to deploy without purchasing additional endpoints. No software, drivers or external power adapters are mentioned in the supplied data. The bundled hardware delivers a complete point-to-point extension kit.

Questions about this item

What type of cable is needed between the transmitter and receiver to reach 50 m?

A single Cat5e or better Ethernet cable up to 50 m carries the 4K 18 Gbps signal between the two units.

Will a legacy 1080p display work with the receiver?

Yes, the receiver downscales the incoming 4K stream so older 1080p screens show a picture without extra settings.

How can I confirm the extender is passing the full 18 Gbps bandwidth?

Play a 4K HDR test pattern; if the display reports 4K at 18 Gbps with no sparkles or fallback, the link is running at spec.
