4.8.1 Connecting the 780B to the Audio Rendering Device
Use the following procedures to make the physical connections from the 780B to the audio rendering device
under test.
1. Make the cable connection between the appropriate the 780B video output connector (e.g. HDMI OUT,
SPDIF or OPTICAL) and the input connector of the audio rendering device using the cables supplied.
