48 HP Digital Entertainment Center
Digital Home Theater Audio
The HP Digital Entertainment Center supports digital
audio output.
■ For TV and music: two-channel stereo. (Your AV
receiver may separate the audio signal into multiple
channels.)
■ For DVD playback: the multiple channel Dolby
Digital 5.1 or DTS Digital encoded audio signal
passes to your AV receiver for decoding. Refer to
your AV receiver product documentation.
You can connect the either coaxial or optical digital audio
cable, depending on your system. If you have both
cables, connect only one cable. Do not connect analog
multichannel speaker outputs if you connect the digital
output.
■ Insert optical cords straight in until they click into
place.
■ Do not bend or tie optical cords.
To connect digital audio from your HP Digital
Entertainment Center to an AV receiver:
1 Connect the Digital Out connector on the back panel
of your HP Digital Entertainment Center, to the Digital
Input (SPDIF) on your AV receiver or digital audio
system.
2 Select the AV receiver input.
3 Use the AV receiver to adjust the volume.

such as having more speakers.
