DCT3400 User Guide
Connecting HDTV – Audio Only
Connect the stereo audio cable to the AUDIO R and L connectors on the cable terminal and the corresponding connectors on the HDTV.
If your equipment supports it, use the OPTICAL SPDIF or coaxial digital SPDIF outputs instead of the AUDIO R and L outputs. In most cases, S/PDIF offers better audio quality, including support for Dolby 5.1 Surround Sound.
HDMI and IEEE1394 carry video and audio. If you connect the DCT3400 to your HDTV using HDMI or IEEE1394, no additional audio connections to the TV are necessary.
For information on configuring your DCT3400 settings, see “Optimizing Your Cable Terminal for High Definition TV.”
