AV repeater SpeaKa Professional SP-5973388

The SpeaKa Professional SP-5973388 AV repeater is an active HDMI amplifier designed to extend 4K (3840 x 2160) signals over longer cable runs. Unlike conventional passive HDMI cables that typically maintain signal integrity only up to about 10 m, this repeater supports stable transmission to distances up to 40 m and allows cascading of up to five repeaters for greater reach. Its compact housing (28 mm × 51 mm × 13 mm) and wired HDMI connectivity make it suitable for integration into home or professional AV setups without requiring an external power supply.

Advantages

The repeater enables longer 4K HDMI runs with active signal amplification, supports cascading of multiple units to achieve extended lengths, and preserves wired HDMI signal stability without the need for an external power adapter. Its small form factor simplifies installation in confined spaces.

Suitable for

• Extending HDMI connections for 4K TVs and projectors
• Long cable runs in conference rooms and classrooms
• Home theater installations requiring longer HDMI distances
• AV setups where external power outlets are limited

How to use

Connect the HDMI source (for example a Blu-ray player, set-top box or PC) to the repeater input and connect the repeater output to the display device using HDMI cable(s). For longer distances, use a single repeater to reach up to 40 m. To extend beyond that, connect repeaters in series — up to five units — following the same input/output connections for each unit. Ensure all HDMI connectors are firmly seated for stable transmission.
