Connecting Audio
Sound Connector Jacks
The audio connectors are RCA type jacks that connect
from the back of your HP Digital Entertainment Center to
a TV, powered speakers or an AV receiver.
The HP Digital Entertainment Center has separate Audio
In connections (analog).
The HP Digital Entertainment Center has two Digital
Audio Out connections (SPDIF) that are coaxial and
optical. Use analog Audio 7.1 Pre-out or Digital Audio
Out connectors, but not both. Use only one Digital Audio
Out connector at a time.
The HP Digital Entertainment Center does not have digital
audio in connections.
Speaker Types
A stereo speaker set is a left-right, two-channel speaker
system.
A multichannel audio speaker system has a subwoofer,
left-right front and left-right surround channel, and it may
include a left-right surround back channel and a center
speaker. Surround back speakers are included in more
advanced 7.1 systems. A subwoofer provides enhanced
bass sounds.
The “.1” indicates a subwoofer. For example, 7.1
channels refer to an eight-speaker mode and uses two
front speakers (left-right), two side speakers (left-right),
two rear speakers (left-right), a center speaker, and a
subwoofer.
See “Speaker Configurations” on page 38 for more
information on speaker arrangements.
Audio amplifiers
The HP Digital Entertainment Center does not supply an
amplified audio signal. You can connect the HP Digital
Entertainment Center to:
■ Passive speakers connected through a home audio
system. A home audio system does not require active
speakers because the receiver provides
amplification.
■ Active (powered) speakers directly. An active
speaker system must have its own power cord.

If your audio equipment has multiple input
and output connections, then it has front
panel input and output switches.
You must select the correct input and output
from the audio equipment front panel or
remote control to hear sound and see video.
