## Long description

This active StarTech HDMI cable provides a reliable High Speed HDMI 1.4b connection over a 20 m (66 ft) distance. Designed with built-in amplifier circuitry, the cable boosts the HDMI signal without requiring external power and supports 4K at 30 Hz, 3D formats and Audio Return Channel (ARC). Both ends feature gold-plated HDMI Type A male connectors and the cable is CL2 in‑wall rated for safe residential and commercial installations. The cable uses a unidirectional design—observe the Source and Display labels on the connectors to ensure correct installation.
Advantages
The active design maintains signal integrity over extended distances, avoiding common degradation seen with passive cables. CL2 in‑wall rating allows discreet installation behind walls for clean audiovisual setups. Gold‑plated HDMI A connectors reduce corrosion and improve contact reliability, while support for Ethernet, ARC and 3D formats ensures compatibility with a range of AV devices.
Suitable for
Connecting TVs, projectors and monitors located up to 20 m from the source
In‑wall AV installations in homes, conference rooms and classrooms
Home theatre systems requiring 4K 30 Hz, ARC or 3D support
Setups that need a dependable long-reach HDMI connection without external signal boosters

How to use
Confirm the cable orientation by locating the Source and Display labels on the HDMI connectors. Connect the end labeled Source to your HDMI output device (for example, a Blu‑ray player, media player or AV receiver) and connect the end labeled Display to your TV, projector or monitor. After both ends are connected, power on the devices and select the appropriate HDMI input on the display. No external power supply is required for the cable’s amplifier circuitry.
Usage recommendations
For in‑wall installations, follow local electrical and building codes and ensure the cable path avoids sharp bends and sources of electrical interference. If you require bi‑directional signal flow or longer distances than 20 m, consider alternative active extenders or fiber HDMI solutions. Always verify device compatibility with HDMI 1.4b features such as ARC and Ethernet before installation.
