Product Information ● This HDMI switcher allows you to switch between video and audio from multiple HDMI devices and output them to a single TV. ● It can connect two HDMI devices such as HDD recorders, BD/DVD players, game consoles (PlayStation(R)4, Nintendo Switch(TM), etc.), and Chromecast. ● Even if your TV doesn't have enough HDMI input terminals, you can still use HDMI devices without having to swap cables. ● It draws power from the HDMI devices, so you don't need an external power supply like an AC adapter. ● It has an external power port to ensure stable operation even if the power supply from the HDMI devices is insufficient. If necessary, supply power to the external power port (USB micro-B terminal) on the side of the main unit. (※USB cable and AC adapter are sold separately). ● It has an automatic switching function that automatically switches to the connected device when an HDMI device is turned on. ● ※ You can switch to a device that is already on by using the button on the top of the main unit. ● It has an ultra-compact design that won't get in the way when placed around your TV. ● You can route all HDMI cables in the same direction for a neat and tidy setup. ● It has non-slip feet to securely fix the main unit in place. ● It has LED lamps to indicate the input status. ※ No box included.
