Gefen's 4x2 Switcher for HDMI has four HDMI inputs and two HDMI outputs. Up to four HD audio/video sources are connected at one time to the HDMI inputs such as satellite systems and Blu-ray players. Two mirrored HDMI outputs send HD audio/video signals to two HDTV displays simultaneously. A convenient S/PDIF digital audio out allows connection to an external audio video receiver if desired.
