4x1 (4:1) HDMI Video + Digital Optical Audio Switch Switcher + 3D Support

This 4X1 HDMI switcher with digital audio is a professional HDMI switcher with remote. By simply pressing a button on the remote, you can select your desired HDMI source to be routed to a high definition display. Switcher is tested to guarantee resolution up to 1080p without signal degradation. The great advantage of this switcher is that you can now route your digital audio though it as well, rather then separately going in to the receiver. With a click of a button you can switch HDMI (video) and Optical or Coaxial Audio. This simple advantage will make you life much easier, as you will only have 2 cables going out of the switch (HDMI and Optical or Coaxial), one to the TV and another to an Audio Receiver. We recommend to use high quality HDMI cables for the best signal transfer.
