Placing Speakers
SUBWOOFER
All stereo-encoded information is heard through the satellite speakers. The subwoofer contains no stereo imaging, and its sound is non­directional. 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
Arrange the front satellites to suit your listening tastes—from right next to the monitor to as far apart as the speaker cords allow. The rear satellites should be placed slightly behind you, or as far back as the cords allow. The same principle applies to wall-mounted rear speakers.
Place the center satellite either on top or below the center of the monitor.
For optimum sound, all satellites should be placed at or slightly above ear level, and in an arrangement that offers the most satisfying results.
Note: The satellite speakers ARE magnetically shielded and can be placed close to video displays such as TVs and computer monitors without distorting the image.
Making Connections
WARNING:
Do not insert the speaker system’s power plug into an AC 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 251 system’s inputs.
To ensure first-time operation as expected, carefully follow the connection sequences described below in the order indicated for your particular application. Setup is fast and easy: Simply connect the audio source inputs and the satellite speakers to the rear of the subwoofer.
SATELLITE SPEAKERS
The satellite speakers must be connected to the subwoofer. To make set­up easy, the input jacks on the subwoofer are color-coded to the jacks on the subwoofer cables.
The RIGHT FRONT jack is an orange mini-DIN connector, connected to the right satellite, which is different from the other jacks.
Notice that the DIN plug has an arrow. For easy insertion of the DIN connector, the arrow on the connector must face up.
INPUTS
Various connection schemes between your audio source and the 251 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

Bad connection.
Bass setting is too high.
Subwoofer too close to monitor.
Press Power button on the front of the right satellite.
Check to see if the “Power On” LED is illuminated on the rear of the subwoofer. If not, connect AC power.
If the subwoofer’s AC power cord is plugged into a surge protector, make sure the surge protector is switched on.
Plug another device into the wall outlet (same jack) to verify the outlet is working.
Verify the subwoofer’s AC power cord is plugged into the wall outlet.
Verify the Power button has been pressed and the green LED is illuminated.
Turn the volume knob clockwise to raise the volume.
Check volume level on the computer sound card or alternate audio source device, and set at mid-level.
Check plug connections on both the subwoofer and source. Make sure the signal cables are inserted firmly into the correct jacks.
Make sure the green 3.5 mm stereo cable is connected and fully inserted into the “line-out” jack of the audio source.
Test the speakers on another audio device. Remove the green audio cable from the audio source device and connect it to the “line-out” or headphone jack of another audio source.
Change the position of the switch.
Increase the rear or center speaker volume level.
Check all cables. Make sure they are connected to “line-out” or “audio-out” jack on your sound card or other audio source– NOT “speaker-out.”
Check the Windows volume control and decrease if necessary.
Unplug the stereo cable from the audio source. Then plug it into the headphone jack of an alternate audio source (e.g., Walkman, Discman or FM radio).
Decrease master volume level.
Adjust the Windows volume and balance controls to the center as a starting point, then adjust the level on the speaker using the volume control.
.WAV files are often of poor quality. So distortion and noise are easily noticed with high-powered speakers. Try a different sound source such as a music CD.
Move your speakers to see if the interference goes away. If not, you may be able to purchase a shielded stereo cable from your local electronics store.
Adjust the bass level on the rear of the subwoofer.
Many .WAV and .MID files often have little low-frequency content and sound flat when you listen to them on a computer. Try a song with more bass– something from your CD collection.
Some low hum may be detected when your speaker system is powered on without an audio source playing, or when the volume is set at an extremely low level.
Unplug the power cord from the surge protector (if used), and plug directly into an AC wall outlet.
Move your cables. Check to ensure they are making a clear connection.
Disconnect your green stereo cable from the audio source. If the loud hum goes away, lower the volume on the audio source.
Lower the master volume or bass level on your computer, portable device, etc.
Adjust the bass level on the subwoofer.
Check to make sure that all cables are connected properly and are making a clear connection.
Decrease the bass level on the subwoofer.
Because the subwoofer is not magnetically shielded, it can cause distortion if it’s too close to your monitor. Move the subwoofer so it’s at least 2 feet from your monitor.
