SOURCE: how to repair atp3 altec lansing

Best bet would be to just strip the wire with a wire stripper or utility knife and twist the bare ends together to fix the connection. A little electrical tape around those wires and you should be almost good as new. Of course you might notice some difference in quality but I'm pretty sure the only way round that would be replacing the cable.

Try it out and let me know how it works out for you. If you know how to solder it might be a good idea to solder the connection as well.

SOURCE: need wiring and 9pin connector diagram

Dell (Altec Lansing) A425 Subwoofer Pinouts

This is a standard female DB-9 serial port.
Here are the pinouts.

Pin 1 = Left Speaker Out +

Pin 2 = Left Speaker Out - (Common Ground)

Pin 3 = Left Line In +

Pin 4 = Right Line In +

Pin 5 = Left/Right line In - (Common Ground)

Pin 6 = Right Speaker Out +

Pin 7 = Right Speaker Out - (Common Ground)

Pin 8 = Power A

Pin 9 = Power B

Jumper (short) Power A to B to turn on.
If you want a volume control you need to put one on the inputs. You will buy buy a stereo volume control or potentiometer.
Here is some info on how to do this.

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.

Is there a way to use the Altec Lansing VS4121 Subwoofer as a stand alone?


Normally these low end systems components that depend on each other and cannot be interchangeable from other system. So if one of the components (sub woofer or right control satellite speaker) breaks or gets lost the whole system is unusable...
I was in the same situation. Got a sub woofer from VS4121 without original satellite speakers. I acquired satellite speakers from Altec Lansing 251 which used same connectors but the internal wiring was different and incompatible out of the box. Speakers are also glued together so it is impossible to open without damaging it. Not to mention there is no service documentation anywhere..
But if you like electronics you can try to make something based on the information bellow:
Altec Lansing VS4121 connector pinout
If you take the male connector (from right satellite speaker) and look at the pins and number them first row from left to right pins 1-3, second row pins 4-7, the bottom row pins 8-9 and the circle enclosure as 0
0 - Ground
1 - Speaker Right
2 - Treble (seems just like voltage control but may need to be confirmed: Min=0V; Max=voltage from Volume control Pin 9)
3 - Head Set Right
4 - Bass signal (not sure what the exact original design is as I have not opened the speaker) But seems like they use 50K potentiometer and some sort of RC low pass filter configuration. When potentiometer is set to Min it is shorted with ground. When set to Max it is taking signal from Right and Left Head Set (pins 3 and 5) combined through some larger resistors and low pass filter.
5 - Head Set Left
6 - Ground for Head set (grounds 0 and 6 seems to be connected in the subwofer but within the right satelite speaker they seem to be isolated with separate leads to sub)
7 - Power ON/OFF. When OFF or head set jack plugged = 0V; When ON and head set jack unplugged = 5V
8 - 5V Power in
9 - Volume (min=0V; max=5V). It seems they use 50K potentiometer but probably anything >10k should work.
At minimum for standalone sub woofer you will need to implement:
- Power On.Off (switch between pins 8,7)
- Volume control (50k potentiometer (probably anything beteen 10k and 50k will do)between pin 7 and 0 with variable output to pin 9
- Bass control - join two resistors R (I used 7k) and lets call this join point A. Attach other ends of the resistors to pins 3 and 5 respectively. Attach 50k potentiometer (I used 10k) between point A and ground 0. Attach Variable pin of the potentiometer to pin 4 (Bass input signal). Attach capacitor C between Pin 4 and Ground pin 0 (I used Electrolytic 1uF with negative end to ground) . Resistor R and capacitor C should make simple passive low pass filter (Google for formula) that should bypass anf frequency higher than 80-120Hz to ground and feed frequencies lower than 80-120Hz to pin 4.
PS: I managed to hack 251 control satellite speaker to somewhat work with VS 4121 Subwoofer but that is another subject. All electronic parts were salvaged from old broken TV so total cost was $0 but took several days of tinkering for speakers that I could buy used for $10-20 :)

I need to figure out how to open up the subwoofer for the Altec Lansing vs2121 model. Thank you


theres no on/off button for the subwoofer. once you plugged in the power cable,turn on the speaker system by turning the VOLUME knob on the right satellite until you hear a click sound.
An LED will light on the front of the right satellite when the power is ON. if you still dont hear any sound from the sub woofer then check to make sure that all cables are connected properly and are making a clear connection.

hope this help

No Power (LED off) in the Altec Lansing VS4121


There is no way to open the satellite speaker without destroying it. I tried and found that the whole thing was glued together. Mine is now destroyed
