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. Still not working? Then try unplugging 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
Q. My speakers give off a crackling sound (or static, or other noise).
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
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.
A. Yes, as long as your TV or Stereo has an unamplified 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
Q. I have very little bass coming from my Subwoofer. How do I increase
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
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 641 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?

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

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
