SOURCE: Finding replacement Power Supply for Altec Lansing

I did the same! Thanks for suggesting a call to Customer Support (800)258+3288. The guy didn't seem overly pleased to help, but he did promise to send me a new power supply. Also, he said that they don't make the iM7 anymore, but I had already found out that the iM9 uses the same power supply. I, too, will wait and see.

SOURCE: What's the volt & amps of Altec Lansing AVS300 2.1 speaker system

Your adapter is Part No. AVX300-A6859, Model No. 9701-00748-IUND.
Or You could get a universal that is rated for output of 18volt DC, 650ma, Center Positive.
I have used a 15volt DC, 900 ma with no problem, but I never run the volume high.

Good Luck

SOURCE: Scratchy loud noise when volume dial is turned

It means that the volume pot is dirty.You need to find a way to get some WD-40 into the pot.This usualy requires that you take the access to the inside off and spray right inside the pot.Once you do this move the volume dial from min to max a few times and it should fix it.

SOURCE: I have Altec Lansing AVS 300 multimedia speakers with no power

Unfortunately the subwoofer supplies the power to the amp on the speakers, Once again I have the solution,
These speakers are factory molded so that the only way to open them is to break the factory seal
this can be done by sharply rapping the seam at the bottom of the speaker with a heavy screwdriver handle or something similar.
Now you need to supply power to the amp...If you do not have the subwoofer you will need a 4.5volt power supply, after removing the board from the casing find the red white and black wires connecting
the orange plug wire to it, Personally I removed the entire cord from the unit, shough you can splice in at this point if you desire.
Connect the white lead to your posative on your power supply by either splicing or soldering, connect the ground to the heat sink using the screw that is already there holding the chip to the sink. reassemble the speaker.....super glue... and you are now in business.

Sub Speaker giving intermittent loud crackling and sharp loud popping sounds even with main volume control turned off. Crackling sound can be reduced by turning sub volume control off.


It may be the control itself too. In time, these controls can get dust build up inside it. There are volume control spray cleaners available from Radio Shack or other electronic parts stores. The cheat on cleaning the control is to just rotate it from stop to stop as many times as it takes to clear the noise.

Why does it emit a loud whistle when turned on?


I got rid of my Altec Lansing because I got white noise when the unit was turned OFF. They are not a good make. You can try moving any wires or magnetic influence away from them. I now own Bowers and Wilkins MM1 speakers which are amazing.

Sounds like a problem in the speakers' internal power supply, maybe a faulty capacitor. Speakers need to be looked at by a technician, or replaced with a new set.

My subvoofer burs


Induced noise - running signal wire too close to electrical cables.

Faulty/damaged Input reciever (jack) on subwoofer - test by isolating PC, and attaching iPod or other device to check for noise instead.

If the noise is not present when using the isolated source, your sound card output jack is bad, or the soundcard itself.

Thank you for using FixYa - A FixYa rating is appreciated!

Speakers Died?


No, I think you've fried only the fuse of Altec Lansing. Check at the back of the main unit (subwoofer) if there's a fuse box (should look like head of the plastic bolt). If not than turn it off, unplug it and open op the main unit and check for the fuse. It should look like this:0a68355.jpg

If the metal wire inside of it is broken than you should buy new fuse of same amperage (it should be engraved on metal part of the fuse or printed on glass tube).

Crackling Sound From Subwoofer


Check any wiring coming or going to the subwoofer. It sounds like it could be a loose connection.  Is there a LFE or bass boost knob on your subwoofer? Does turning that up/down cause the crackling (if it exists). If so, you could use some tuner cleaner to clean the contacts on the potentiometer knob.

If the crackling is on the subwoofer only, it might be damaged from bottoming out.  See if you can remove the baffle or grille covering the woofer and inspect for visual problems. You can also try to lighly push in and out on the subwoofer to hear if it makes any scraping sounds. If so, it is definitely damaged and the driver will have to be replaced.
