  If your Altec Lansing Speakers aren't producing any sound, there are a few things to check: * Ensure the AC line cord from the back of the Subwoofer is plugged into the wall outlet. * Increase the system Master Volume by turning the rotary knob to the right. * Verify the audio cable is correctly connected to the audio source and that the connections are secure on both the subwoofer and the source. Ensure the cables are firmly inserted into the correct jacks. * Confirm that the lime green 3.5 mm stereo jack is connected to the line-out jack of the audio source and is fully inserted.

  If there is no sound coming from your Altec Lansing Subwoofer: * Test the speakers on another audio device by connecting the audio cable to the line-out or headphone jack of another audio source. * If your model has a Subwoofer Volume control, adjust it to increase the Subwoofer volume. If there is a Bass Selector function on the System Controller, adjust it and raise the volume level. * If listening to .WAV files, try listening to a CD, as .WAV files often have little low frequency content.

What to do if my Altec Lansing Speaker System has distorted sound?

  Jennifer BartlettAug 27, 2025
  Sound distortion can occur due to several reasons. Try decreasing the speaker system's master volume level. If using Windows, adjust the volume and balance controls to the center, then use the speaker controller to adjust the volume. Also, the sound source itself might be distorted; for example, .WAV files are often of poor quality. Try using a different sound source like a music CD.

  If all LEDs are unlit, it indicates a power issue. First, press the Power On button on the System Controller. Check that the AC cord is connected to the wall outlet. If using a surge suppressor, ensure it is switched on. Also, make sure the System Controller is connected to the Subwoofer. Finally, plug another device into the wall outlet to ensure it is functioning.

  First, check the input cable from the speaker to the audio source, ensuring it's connected to the line-out jack (the un-amplified source). Verify all cables are plugged in correctly and have a secure connection. If the issue persists, unplug the cable from the back of the computer and insert the stereo plug into the headphone jack of an alternate source like a Walkman or FM radio and play music. If the speakers then work, adjust your volume and balance controls in your audio source or Windows settings.

Why do my Altec Lansing Speakers make a crackling sound?
- R
  Rachel SharpAug 31, 2025
  If your Altec Lansing Speakers are making crackling or static noises, here's what you can do: 1. Check that all cables are connected to the line-out or audio-out jack on your sound card or audio source, and not the speaker-out. 2. Ensure the volume control in Windows is not set higher than halfway. 3. If the noise persists, try using an alternate audio source (like a Walkman or FM radio) by plugging the stereo cable into its headphone jack.

How to stop loud hum from Altec Lansing Subwoofer?
- D
  daisybrownSep 3, 2025
  If you are experiencing a loud hum from your Altec Lansing Subwoofer, try these solutions: * Move the power cord from the power surge protector (if applicable) and plug it directly into an AC wall outlet. * Check the cables to ensure they are making a good connection. * If disconnecting the stereo cable from the audio source makes the hum disappear, adjust the volume control in your audio source, as you might be overdriving the volume settings on your speaker system.
