Q
. When connected to my computer sound card, should I use the Windows
volume control to adjust the volume of my speakers?
A. No. Adjust the Windows controls to about center as a starting point and
then use the speaker controller to adjust volume control. If the volume is
turned too high on the sound card, it can distort the sound.
Q. One and sometimes both of my speakers do not work.
A. Check the input cable from speaker to the audio source and make sure
that it is connected to the line-out jack, which is the un-amplified source.
Make sure all the cables are plugged in correctly and have a good
connection. Unplug the cable from the back of the computer, and insert the
stereo plug into the headphone jack of an alternate source (e.g., Walkman,
Discman or FM radio) and play music. If the speakers work, you may need to
adjust your volume and balance controls in your audio source, or Windows, if
connected to your computer's sound card.
Q. My speakers give off a crackling sound (or static, or other noise). What
could be wrong?
A. Check all cables and make sure that they are connected to line-out or
audio-out jack on your sound card or other audio source, and NOT speaker-
out. If your audio source is your computer, check the volume control in
Windows: make sure that it is not set more than halfway. Setting this level
too high can cause sound distortion. If this does not stop the noise, unplug
the cable from the audio source and use an alternate source (e.g., Walkman,
Discman or FM radio) by plugging the stereo cable into the headphone jack.
If the noise goes away, you may have a problem with your audio source.
Q. What can cause radio feedback?
A. If you are living near a radio tower you could have interference caused by
radio frequency. Try moving your speakers to see if the interference goes
away; if not, you may be able to purchase a stereo cable from your local
retailer that has a higher percentage of shielding.
Q. Can I hook my speakers to my TV or Stereo?
A. Yes, as long as your TV or Stereo has an un-amplified source which is
line-out (check your TV or Stereo owners manual). These speakers may be
used with any audio device that has a stereo headphone jack. You may also
need a cable that has RCA jacks on one end and a 1/8 inch stereo connector
at the other end (these may be purchased at most local electronics stores).
Q
. I have very little bass coming from my subwoofer. How do I increase the
bass output?
A. Adjust the BASS control through your audio sound source (computer
sound card control, CD player control, etc.). Check to make sure that all of
your cables are hooked up correctly and are making a good connection.
Q. I have a low hum coming from my subwoofer. Is this normal?
A. Yes. The AC in your house is at 60 cycles per second, which is within
the audio frequency of your subwoofer. Some low hum is natural and can be
detected when your speaker system is powered on without source audio
playing, or when volume is set at an extremely low level.
Q. I have a loud hum coming from my subwoofer. What should I do?
A. Move the power cord from the power surge protector (if applicable) and
plug directly into an AC wall outlet. Move your cables and check to see that
they are making a good connection. If you disconnect your stereo cable from
the audio source and the loud hum goes away, then you may need to adjust
the volume control in your audio source as you may be overdriving the
volume settings on your speaker system. If you are using your 4100
speakers with your computer system, just click on the speaker icon located
next to the digital clock to the lower right of your Windows 9X or 2000 screen
and adjust the volume.
Q. When I put my subwoofer on my desk my monitor distorts. Why?
A
. The subwoofer is not magnetically shielded, and this can cause distortion
if it is less than 3 feet from your monitor.
Q. The DIN connector from the controller has multiple pins on one end, and
when trying to attach this cable I noticed that some of the pins are bent, so I
am not able to insert the cable into subwoofer. What should I do?
A
. Try to gently straighten the pins with tweezers or very small pliers. If this
does not work, then contact the Altec Lansing Consumer Support Department
for further instructions.
