Advantages

The AV repeater preserves high-definition video up to 4K (3840 x 2160) and uses standard HDMI Type A connectors for compatibility with most HDMI sources and displays. Its small size and low weight (0.021 kg) make it unobtrusive and simple to position in rack installations or behind equipment. The device enables signal extension without requiring a powered distribution amplifier or complex cabling changes.

• Extending HDMI connections for TVs and monitors up to 40 m

How to use

Connect an HDMI cable from the source device to the repeater input and connect a second HDMI cable from the repeater output to the display. Ensure cables are fully inserted into the HDMI Type A connectors. Place the repeater near the midpoint of the overall cable run or at the equipment connection point; no external power supply is required beyond the connected HDMI devices. Verify the display resolution settings on the source device to achieve the desired output up to 3840 x 2160.

Recommendations

Use high-quality, well-shielded HDMI cables rated for the required length to maintain signal integrity. For runs close to the 40 m limit, test the setup at the intended resolution and consider shorter cable lengths or active/extender solutions if signal degradation occurs.
