About Setup A: Using an HDMI cable to connect a TV
(optional home theater shown)
This is the most basic setup, with only an HDTV and optional home theater connected.
The set-top has a high-definition multimedia interface (HDMI) connector.
The HDTV has an HDMI, so use an HDMI cable (1) to connect it to the set-top’s HDMI.
HDMI carries both high-resolution digital video and digital audio.
To enhance the sound, you can connect a home theater receiver.
There is a choice of two S/PDIF outputs: (i) electrical (labeled DIGITAL AUDIO OUT, which is shown connected by cable 8 in the
diagram, opposite) and (ii) optical (labeled OPTICAL AUDIO OUT).
When you add a home theater receiver, the set-top’s audio connection to the TV (via HDMI) is not needed, so you may wish to mute
(turn off) the audio on the TV.
