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,

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.
