BOX CONTENTS
•Two “two in one” satellite speakers with removable grills
•One center speaker with removable grill
•One subwoofer
•Color-coded cables
•User’s guide and quick connect instructions
PLACING SPEAKERS
SUBWOOFER
All stereo-encoded information is heard through the satellite speakers. The subwoofer contains no stereo imaging, and its sound is non-directional. As a result, the subwoofer doesn’t have to be placed in any particular relationship to the satellites. However, placing the subwoofer on the floor close to a wall or room corner provides better bass efficiency and optimum sound.
Warning: The subwoofer is not magnetically shielded. As such, it SHOULD be placed at least 2 feet (0.6m) from TVs, computer monitors, computer hard drives or any other magnetic media (e.g. floppy disks, Zip disks, computer or audio tapes, etc.).
SATELLITE SPEAKERS
•Place the left satellite speaker to the left of the TV or computer monitor, and the right satellite speaker to the right.
•Direct the lower part of each satellite speaker toward the listener. The left front/surround or upper portion of the left satellite will then be angled toward the left, and the right front/surround or upper portion of the right satellite toward the right.
•Make sure each satellite speaker is at equal distance from the listener.
•Note: In order to maximize the surround sound effect, do not place the satellites too close to an adjacent wall.
CENTER SPEAKER
Place the center speaker either on top or below the center of the TV or computer monitor.
MAKING CONNECTIONS
Warning: Do not insert the speaker system’s power plug into a wall outlet until all connections are made. Also, turn off audio source (i.e., your PC, MP3 player, Sony PlayStation, etc.) before connecting the outputs to the speaker system’s inputs.
To ensure first-time operation as expected, please carefully follow the connection sequences described below in the order indicated.
SPEAKER SYSTEM
To set-up the speaker system:
1.Connect each satellite to the subwoofer by plugging each color-coded DIN connector into the corresponding output on the back of the subwoofer.
2.Connect the center speaker to the subwoofer by plugging the color-coded
3.5 mm connector into the corresponding output on the back of the subwoofer.
Note: If you don’t have space for the center channel, simply remove it. The GT5051 system’s center channel auto-detect feature will automatically create a “phantom” center channel by re-routing the center channel’s audio information to the left and right speakers.
INPUTS
Various connection schemes between your audio source and the speaker system are available. Determine if you’ll be setting up the speaker system for PC audio/PC gaming, DVD playback, console gaming or with portable audio devices (such as MP3 or portable CD players), then skip to the appropriate section.
PC AUDIO/PC GAMING/DVD PLAYBACK
Sound cards designed for PC gaming or DVD playback have unique audio outputs. Typically, the outputs will be marked as “front output,” “rear output” and “LFE/center output.” In some cases, slightly different terminology may be used. The sound card’s documentation should help you determine which outputs to use with your speaker system.
6-CHANNEL/5.1 SOUND CARDS WITH ANALOG OUTPUTS
1.Locate the green, black, and orange 3.5 mm cables.
2.Insert one end of the green cable into the computer soundcard’s green output, and the other end into the color-coded input labeled “front,” located on the back of the subwoofer.
3.Insert one end of the black cable into the computer soundcard’s black output, and the other end into the color-coded input labeled “rear,” located on the back of the subwoofer.
4.Insert one end of the orange cable into the computer soundcard’s orange output, and the other end into the color-coded input labeled “center,” located on the back of the subwoofer.
5.Be sure that the switch on the back of the subwoofer is in the 6-channel position.
4-CHANNEL GAMING SOUND CARDS
1.Locate the green and black 3.5 mm cables.
2.Insert one end of the green cable into the computer soundcard’s green output, and the other end into the color-coded input labeled “front,” located on the back of the subwoofer.
3.Insert one end of the black cable into the computer soundcard’s black output, and the other end into the color-coded input labeled “rear,” located on the back of the subwoofer.
4.Be sure that the switch on the back of the subwoofer is in the 2/4-channel position.
2-CHANNEL/STEREO SOUND CARDS
1.Locate the green 3.5 mm cable.
2.Insert one end of the green cable into the computer soundcard’s green output, and the other end into the color-coded input labeled “front,” located on the back of the subwoofer.
3.Be sure that the switch on the back of the subwoofer is in the 2/4-channel position.
CONSOLE GAMING OR TV
Most console game systems and TVs feature dual-RCA outputs. To connect your speakers, follow the steps below:
1.Make sure the power to your console gaming system or TV is turned off.
2.Locate the red and white RCA cable that came with your console gaming system or TV.
3.Connect one end of the RCA cable to the matching red and white RCA jacks located on the back of the subwoofer, and the other end to the back of your console gaming system or TV.
4.Be sure that the switch on the back of the subwoofer is in the 2/4-channel position.
PORTABLE AUDIO DEVICES (MP3, PORTABLE CD PLAYERS, ETC.)
1.Locate the green 3.5 mm cable.
2.Insert one end of the green cable into the headphone jack of the portable audio device, and the other end into the input labeled “AUX,” located on the back of the subwoofer.
3.Be sure that the switch on the back of the subwoofer is in the 2/4-channel position.
POWERING ON
1.After all other connections are made, plug the AC power cord (on the back of subwoofer) into a wall outlet. The speaker system is now ready to operate.
2.Turn on the audio source.
3.Turn on the speaker system by pushing the On/Off button located on the top of the right satellite 
. An LED will light up when the power is ON.
Note: To avoid hearing a popping sound when you turn on your Altec Lansing speaker system, always turn on your audio source first.

MASTER VOLUME
The VOLUME knob on the top of the right satellite controls the master volume. Turn the knob clockwise to increase the volume and counterclockwise to decrease the volume.
SURROUND VOLUME
When the SURROUND button on the top of the right satellite is pushed, the VOLUME knob controls the volume of the left and right surround speakers. Adjust this control as necessary to create the optimal balance of surround information. The surround volume control operates in the same manner even on computers that only have stereo outputs when the switch on the back of the subwoofer is in the 2/4-channel position.
SYSTEM SPECIFICATIONS*
CENTER VOLUME
When the CENTER button on the top of the right satellite is pushed, the VOLUME knob controls the volume of the center speaker. If the center speaker is not in use, this action will control the level of the center information from the left and right satellites. Adjust this control as necessary to achieve a balanced sound.
SUBWOOFER VOLUME
When the SUB button on the top of the right satellite is pushed, the VOLUME knob controls the volume of the subwoofer. Adjust this control as necessary to achieve optimum bass.
HEADPHONES
To use headphones with the system, plug them into the labeled 
jack
on the back of the right satellite. When headphones are connected, the speaker system is muted.
