This compact little HDMI switch box allows you to plug three high definition sources into a single HDMI port on your HDTV or projector, and then switch between them using a button on the unit or the supplied remote control. Included is an IR sensor on a 1.2m cable to allow the switch to be conveniently located out of sight. Note on longer length cable runs For installations of 20m to 30m we recommend you use LINDYPremium Gold HDMI Cables as their low attenuation design is specially optimised for long cable runs without the need for any additional power requirements. If you are using third party long length HDMI cables however, we recommend you use an optional power supply with this switch.
