Extensor AV DeLOCK 11403 negro

The DeLOCK 11403 AV extender in black is a compact HDMI repeater designed to boost HDMI signal strength and extend cable runs up to a total of 30 m. With small dimensions (26 x 47 x 14 mm) it provides a simple wired solution to connect a PC or laptop to a distant display or TV while maintaining support for resolutions up to Ultra HD (4K) and backward compatibility with Full HD (1080p).

Advantages

This HDMI repeater allows splitting the 30 m total run into an upstream cable (up to 20 m) and a downstream cable (up to 10 m), simplifying installation where long single cables are impractical. Its compact black housing takes minimal space and supports high-resolution transmission without additional power or complex setup, making it suitable for both home and professional environments.

Suitable for

• Extending HDMI connection between a PC or laptop and a TV or monitor
• Situations where a long HDMI run must be split into two segments
• Home theater setups and small conference/meeting rooms

How to use

Connect an HDMI cable (up to 20 m) from your source device (PC or laptop) to the input port of the DeLOCK 11403 repeater. Then connect a second HDMI cable (up to 10 m) from the repeater's output port to your display or TV. Power on the source and display — the repeater functions inline to restore and pass the HDMI signal, preserving the negotiated resolution up to 4K where supported by both source and display.

Recommendations

For best results use high-quality HDMI cables rated for the intended resolution and lengths. Ensure both source and display support the desired resolution (4K) and use shorter cable segments when possible to reduce potential signal degradation.
