What is the HDMI pass-through feature?
The pass-through function sends source signals to a television or display device that is connected to the HDMI OUT jack on the processor instead of to the head mounted unit.
NOTE: The system includes only one HDMI® cable, so a High-Speed HDMI cable must be purchased. A High-Speed HDMI cable that is 5 m or shorter is recommended when connecting a television or other display device to the processor unit.
