This CL2 HDMI cable is approved for in-wall installations. It features a built-in active signal amplifier that allows for a connection distance of up to 10 meters between your HDMI devices without signal loss. The cable is backward compatible with older HDMI specifications and can be used with your existing HDMI devices. The integrated signal amplification actively boosts the HDMI signal without the need for an external power source. The cable supports longer connections than standard HDMI. The active cable offers a thinner wire construction for greater flexibility, making it ideal for in-wall installations.
