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.

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.

Speaker Types

Astereo 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.
