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 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 the audio source (i.e., your PC, MP3 player, Sony PlayStation, etc.) before connecting the outputs to the 5100 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 satellite cables.

1. Connect the orange RCA plug from the RIGHT FRONT satellite into the jack marked RIGHT FRONT on the subwoofer. Repeat this procedure for the LEFT FRONT satellite, connecting the brown RCA plug from the LEFT FRONT satellite to the jack marked LEFT FRONT on the subwoofer.

2. Connect the purple RCA plug from the RIGHT REAR satellite into the jack marked RIGHT REAR on the subwoofer. Repeat this procedure for the LEFT REAR satellite, connecting the gold RCA plug from the LEFT REAR satellite to the jack marked LEFT REAR on the subwoofer.

3. Connect the cyan 3.5mm stereo plug from the CENTER satellite to the jack marked CENTER on the subwoofer.

4. Connect the gray DIN plug from the system controller unit into the DIN jack marked CONTROLLER on the subwoofer. Note that the DIN plug has an arrow. The arrow should be face up for correct insertion into the DIN jack on the subwoofer.

Inputs

Various connection schemes between your audio source and the 5100 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

1. Locate the cables with green, black and yellow 3.5mm stereo plugs.

2. Insert one end of the black, green and yellow plugs into the colorcoded inputs labeled front, rear and center input, located on the rear of the subwoofer.

3. Insert the other end of the black, green and yellow input plugs into the computer sound card’s black, green and yellow outputs.

4. Ensure the mode on the controller is set to the 5.1 position.

Console Gaming

Most console game systems feature dual-RCA outputs. Popular console systems manufacturers include Sony

, Microsoft®, Nintendo®and

Sega®. To connect your speakers, follow the steps below:

1. Make sure your console gaming system is turned off.

2. Locate the AAC1 Y-adapter included with your 5100 speaker system. The AAC1 Y-adapter has a green 3.5mm stereo jack on one end and two RCA jacks on the other—one red and one white.

3. Locate the red and white RCA plugs on the end of the cable connected to the back of your console gaming system. Connect them to the matching red and white RCA jacks on the AAC1 Y-adapter.

4. Locate the cable with the green 3.5mm stereo jack.

5. Insert one end of the green plug into the color-coded input on the rear of the subwoofer labeled front input. Insert the green plug on the other end of this cable into the lime green jack on the AAC1 Y-adapter.

6. Set the mode on the controller to the StereoX2 position.

NOTE: To ensure sound emanates from the center satellite, be sure that the center mix switch on the subwoofer is in the “on” position.

Portable Audio Devices (MP3, Portable CD Players, etc.)

1. Locate the cable with green 3.5mm stereo plugs.

2. Insert one end of the green plug into the color-coded input located on the rear of the subwoofer labeled front input.

3. Insert the other end of the green input plug into the computer stereo (green) output.

4. Set the mode on the controller to the StereoX2 position.

NOTE: To ensure sound emanates from the center satellite, be sure that the center mix switch on the subwoofer is in the “on” position.

Center Channel Operation

If your speaker configuration does not allow for use of the center satellite, simply disconnect the satellite and use the remaining four satellites. When the center satellite is disconnected from the subwoofer, the center signal is mixed into the left and right front satellites.

NOTE: When using the center channel, to ensure sound emanates from the center satellite, be sure that the center mix switch on the subwoofer is in the “on” position.

Center Channel Stand

You will find the center satellite stand in the packaging foam in the groove next to the center satellite. Affix the stand into the mounting holes on the bottom of the center satellite.

Headphones

To use headphones with the system, plug them into the labeled jack on the front of the controller. When headphones are connected, all satellites and the subwoofer are muted.

Power On/Off

Turn on the Altec Lansing 5100 speaker system by first ensuring the power switch, located on the rear of the subwoofer, is in the ON position. Then push the standby button which is located on the System Controller. A green LED will illuminate above the StereoX2 mode button when the unit is fully powered.

If the power switch on the rear of the subwoofer is in the OFF position, the entire unit is shut off.

Master Volume Control

Locate the rotary knob on the System Controller. The rotary knob acts as the Master Volume control for the overall system when no other buttons have been pushed. It is also used to individually adjust the bass, treble and rear sound levels. If any of these functions is selected but not used for a few seconds, the control reverts back to the Master Volume control.

Five LED indicators around the control show the position of the control. In the extreme counterclockwise position, all LEDs are off. As the control is rotated clockwise, the LEDs illuminate one at a time until they reach the maximum position, where all LEDs are glowing.

Bass/Center Control

The Bass and Center buttons are located on the System Controller. When the Bass button is pushed, the bass LED will turn on and the rotary knob will change the level of bass on all speakers, having the greatest effect on the subwoofer. The LEDs around the rotary knob will illuminate one at a time to indicate the level of bass boost or reduction. The center LED indicates the default position. Pushing the bass button again will immediately exit this function.

When the Bass/Center button is pushed and held for three seconds, the Bass/Center LED will flash and the rotary encoder will continue as the center speaker level control.

Treble/Rear Control

When the treble button is pushed, the Treble/Rear LED will illuminate and the rotary knob will change the level of treble on all speakers. The LEDs around the rotary knob illuminate individually to indicate the level of treble boost or reduction. The center LED indicates the default position. Pushing the treble button again will immediately exit this function.

When pushed and held for three seconds, the Treble/Rear LED will flash and the rotary encoder will adjust the rear speaker level control.

Mode Selector

The Tri-Mode Selector button is located on the System Controller. The Tri-Mode selector changes the operation of the system between the three modes: 5.1/4.1/StereoX2. Pressing the Mode button cycles through the three modes.

The 5.1 Mode works with your 6-channel sound card to bring your favorite films to life. In this mode, the Front Input plays on the front satellites, the Rear Input plays on the rear satellites, the Center Input plays through the center speaker and the subwoofer plays from both the Front and the Rear Inputs.

The 4.1 Mode is perfect for gaming with deep, resounding bass and clear highs. In this mode, the Front Input plays on the front satellites, the Rear Input plays on the rear satellites, and the center and subwoofer plays from both the Front and the Rear Inputs.

In Stereo X2 mode (system default), the Front Input plays on both the front and rear satellites, the center satellite and the subwoofer.

NOTE: When using the center channel, to ensure sound emanates from the center satellite, be sure that the center mix switch on the subwoofer is in the “on” position.

The rotary knob reverts to Master Volume control function when a period of three seconds of inactivity occurs after adjusting the bass, treble or rear speaker levels.

The standby button found on the controller denotes a standby mode which mutes the speaker and subwoofer volume. Pressing the standby button again returns the system to its previous settings.

System Reset to Factory Default Settings:

To return to factory default settings, press both the Bass/Center and Treble/Rear buttons at the same time and hold for five seconds. This will reset the bass, treble, mode volume and rear volume settings.

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 computer operating system 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 computer operating system 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 controller.

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 solid connection.

Disconnect your green stereo cable from the subwoofer. 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.

Confirm that all cables are properly connected and are making a solid connection.

Decrease the bass level on the controller.

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 (0.6 M) from your monitor.
