Press Power On button on the System Controller.
Check to see if the LED is illuminated on the rear of the Subwoofer. If
not, connect AC power.
If the AC line cord is plugged into a surge surpressor, make sure the
surge surpressor is switched on.
Connect System Controller to Subwoofer.
Plug another device into the wall outlet (same jack) to insure it is
functioning.
Verify the AC line cord from the back of the Subwoofer is plugged into
the wall outlet.
Verify the Power On switch has been pressed (LED is illuminated).
Turn the rotary knob to the right to raise the system Master Volume.
Check volume level on computer sound card or alternate audio source
device and set at mid level.
Connect audio cable from audio source, check plug connections on both
subwoofer and source. Make sure these signal cables are inserted
firmly into the correct jacks.
Make sure that the lime green 3.5 mm stereo jack is connected to the
line-out jack of the audio source; make sure it is fully inserted.
Test the speakers on another audio device. Remove the audio cable
from the audio source device and connect it to the line-out on another
audio device or the headphone jack of another audio source device.
If your model has a Subwoofer Volume control, try adjusting it to
increase the Subwoofer volume. If your model offers a Bass Selector
function on the System Controller, adjust Select Bass function and raise
volume level.
If listening to .WAV files over a computer sound card connection, try
listening to a CD on your computer CD or DVD player. .WAV files often
have little low frequency content. Try a music signal with more bass.
Power off the Altec Lansing speaker system. Unplug the Subwoofer
from the AC outlet. Check to see if the fuse in the Subwoofer is blown.
To do this, unscrew the black cap at the rear of the Subwoofer and
visually check to see if the filament is in place. If it is not in place, then
the fuse is blown. You'll need to replace it with a T2A (2 amp @ 250
Volt) "SLO BLO" fuse. You can purchase this fuse at most local
electronics stores.
Verify the gray DIN connector is firmly inserted into the DIN jack on the
Subwoofer. Refer to the "Connections" section of your User's Guide for
the correct position of the arrow on the DIN plug. It is important to
insure the pins are aligned from plug to jack.
Press the Mode button on the System Controller to select either Stereo
x2 or gaming Mode.
See User's Guide: "Rear Volume Level Adjustments". Increase the
Rear Volume level.
See User's Guide: "Rear Volume Level Adjustments".
Decrease master volume level.
.WAV files are often of poor quality so distortion and noise are easily
noticed with high powered speakers. Try a different sound source like a
music CD.
Push the Treble button on the System Controller and increase level.
See User's Guide: "Rear Volume Level Adjustments".
Push the Treble button on the System Controller and decrease the level.
See User's Guide: "Rear Volume Level Adjustments"
Push the Bass button on the System Controller and decrease the level.
