HP and Compaq Desktop PCs - Installing and Configuring Speakers Security level: Public ___________________________________________________

In this document: Before you begin Step 1: Place and connect the speakers Step 2: Configure the sound software Step 3: Configure Windows XP Reference: Sound connector examples

This document applies to HP and Compaq Desktop PCs with Windows XP.

HP computers come with a variety of sound options and speaker configurations. Use the sections within the steps below that best matches the sound hardware for your computer. This document also covers connecting your computer to a home stereo system.

Before you begin Make sure that you have the following items:

Enough speaker wire to connect all speakers.

When using desktop speakers, make sure that the speakers are self-amplified. Many sound cards in HP computers output a high quality non-amplified signal.

Step 1: Place and connect the speakers Use one of the following sections depending on your particular speaker configuration:

Desktop speakers (2) or headphones

Monitor speakers

Conventional home stereo system

2.1 computer speaker system

5.1 (or greater) computer speaker system

Desktop computer speakers (2) or headphones

Connect the two desktop speakers to the speaker out connection on the back of the PC.

NOTE: Most PCs do not come with an amplified speaker out connection and require self-amplified speakers. Make sure that you are using self-powered desktop speakers or volume levels may be too low.

Headphones should be connected to the headphone connection on the front of the PC.

After connecting the speaker or headphone cable, continue to Step 2.

Monitor speakers

Connect the monitor speaker cable from the back of the speaker to the speaker out connection on the back of the PC.

For more specific installation and setup instructions, refer to your monitor Setup Guide.

After connecting the speaker or headphone cable, continue to Step 2.

Connecting to a pre-existing home stereo system

Use the following steps to connect an HP computer to a home stereo receiver/amplifier:

Attain the amount of "Y" adapter audio cables as described in the following list. Make sure that the cables are long enough to reach from the back of the computer to the back of the receiver/amplifier. The "Y" adapter cables should have one 1/8 inch (3.5 mm) stereo mini-plug on one end and two RCA style connections on the other.

Figure 1: Y adapter cable

NOTE: If your computer came with on-board audio and you want to use 5.1 speakers, the sound connections on the back of the computer change to speaker out connections. Use the microphone connection (orange) for the center channel out and use the line-in connector (black) for the rear speakers. To change the speaker out configuration, see Configuring on-board audio (AC97).

If your computer only has one speaker out connector, purchase and use one "Y" adapter cable. Do this regardless of how many speakers the stereo has.

If the home stereo system only uses two speakers, purchase one "Y" adapter cable.

If the home stereo system uses four speakers, purchase two "Y" adapter cables.

If the home stereo system uses a 5.1 or greater speaker system, purchase three "Y" adapter cables, plus one more cable for each extra set of speakers beyond the initial 6 (3 cables for a 5.1 system, 4 for a 6.1, and 5 for 7.1).

Turn the stereo receiver/amplifier off.

Connect the stereo mini plug of a "Y" adapter cable into the Primary Front Speaker Out (green) on the back of the computer. Connect the other ends of the "Y" adapter cable into the left and right inputs on the back of the stereo receiver/amplifier (usually CD or DVD in). If your stereo is a 5.1 or higher system, use the front left and right inputs labeled DVD, Surround, 5.1, or 6 Channel inputs.

If you have rear speakers, connect the stereo mini plug of a "Y" adapter cable into the Rear Speaker Out (black) on the back of the computer. Connect the other ends of the "Y" adapter cable into the rear left and right inputs on the back of the stereo receiver/amplifier labeled DVD, Surround, 5.1, or 6 Channel inputs.

If you have a 5.1 or higher channel home stereo system, connect the stereo mini plug of a "Y" adapter cable into the Center or Digital Out (orange) on the back of the computer. Connect the other ends of the "Y" adapter cable into the center and subwoofer inputs on the back of the stereo receiver/amplifier from the section labeled DVD, Surround, 5.1, or 6 Channel inputs. Plug the "Y" adapter cable into the subwoofer connecter on the back of the receiver/amplifier even if a subwoofer is not used.

Turn on the Stereo.

From the stereo receiver/amplifier, select the component that the "Y" adapter cable(s) is plugged into (usually CD, DVD, or 5.1). Continue to Step 2.

Connecting 2.1 computer speakers

Use the following steps to install a 2.1 speaker system. The steps below were created from the setup of a Klipsch 2.1 system, but applies to most 2.1 systems designed for computers.

Unpack the speakers and assemble each component as per the manufacturers instructions,if you have not already done so.

Place the subwoofer (the large cube) on the floor near the computer. Make sure that the connectors on the back of the subwoofer are easily accessible. Position the subwoofer away from the legroom under the desk.

Place the left and right speakers on either side of the monitor/television.

Plug the ends of the speaker wires into the back of each desktop speaker. Connect the other ends of the speaker wires into the red and black connectors on the subwoofer labeled To Satellite Speakers.

The sound cable is thicker and comes from the bottom of the right desktop speaker. Connect the sound cable into the primary front speaker out connector on the back of the computer.

The pre-amp cable is thicker and also comes from the bottom of the right desktop speaker. Connect the pre-amp cable into the round pre-amp connector on the subwoofer.

Plug the subwoofer power cord into a power outlet and turn on the subwoofer.

Turn on the computer and test for sound. Continue to Step 2.

Connecting 5.1, 6.1, or 7.1 computer speakers

The following steps are for installing a speaker system containing several satellite pairs, a subwoofer, and center speaker. The steps below were created from the setup of a Klipsch 5.1 system, but applies to most multi-speaker systems designed for computers.

NOTE: If your computer came with on-board audio and you want to use 5.1 speakers, the sound connections on the back of the computer change to speaker out connections. Use the microphone connection (orange) for the center channel out and use the line-in connector (black) for the rear speakers. To change the speaker out configuration, see Configuring on-board audio (AC97).

Unpack the speakers and assemble each component as per the manufacturers instructions,if you have not already done so.

Place the subwoofer (the large cube) on the floor near the computer. Make sure that the connectors on the back of the subwoofer are easily accessible and the round speaker faces forward.

Place the front, left and right desktop speakers on either side of the monitor/television. Place the side, left and right speaker as close to the sides as possible, this is usually towards the front of a desk. Place the rear, left and right speakers behind the listening area. Try to place all desktop speakers equal distance from the center of your listening area.

Figure 2: 5.1 Speaker Connections

Place the center speaker on top or in front of the television/monitor.

Plug the ends of the speaker wires into the red and black connectors on the back of each speaker. Press the red or black plastic tab in while inserting the end of the speaker wire into the hole. Use the longer speaker wires for the rear desktop speakers.

Insert the other end of the each speaker wire into the matching red and black connector on the subwoofer.

Place the control tower (the volume control component) near the listening area where it is easily accessible.

Plug the cable that comes from the control tower into its matching connector on the back of the subwoofer.

Connect the sound cable with green connectors into Primary Front Speaker Out on the back of the computer. Plug the other end of the cable into the green connector on the subwoofer.

Connect the sound cable with black connectors into Rear Speaker Out on the back of the computer. Plug the other end of the cable into the black connector on the subwoofer next to the green connector.

Connect the sound cable with orange connectors into Center or Digital Out on the back of the computer (see Figure 1). Plug the other end of the cable into the orange connector on the subwoofer.

Turn on the computer and test for sound. Continue to Step 2.
