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: 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: Connect Altec Lansing ADA745 to HD TV RCA output for home theater

It won't work like this due to this being a computer only speaker system. It requires the drivers to work with a computer & a Home theater does not recognize the format. Sorry.

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.

What is 9-pin DIN pinout?


A DIN connector is an electrical connector that was originally standardized by the Deutsches Institut f?r Normung (DIN), the German national standards organization. There are DIN standards for a large number of different connectors, therefore the term "DIN connector" alone does not unambiguously identify any particular type of connector unless the document number of the relevant DIN standard is added (e.g., "DIN 41524 connector").
th?q=9b+pin+din+connectors&w=100&h=100&c=1&rs=1&qlt=90&pid=inlineblock&mkt=en-ph&adlt=moderate&t=1&mw=247 this is just a sample image of 9 din connector

7 WIRES , WHAT COLOR GOES TO WHICH PIN? 2 BLACK , 1 GREEN, ONE YELLOW, ONE WHITE, 2 ORANGE, ONE HEAVIER THAT THE OTHER


Hi Jerry
What Model....?
Using a mobile phone camera would have helped in this situation.
Before taking things apart

I'll be very surprised if someone has the same speaker system in bits somewhere
An electronics guy would trace the wire back to it's source to decide what it's being used for.
Good Luck

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


Normally these low end system components depend on each other and cannot be interchanged with components from other system. So if one of the components (subwoofer or right control satellite speaker) breaks or gets lost the whole system is unusable...
I was in the same situation. Got a subwoofer 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. Speakers are also glued together so it is impossible to open without damaging it. Obviously there is no service documentation anywhere..
But if you like electronics you can try to make something based on the information below:

Altec Lansing VS4121 connector pinout:
Take the male connector (from right satellite speaker) and number pins in first row from left to right as 1-3, pins in the second row as 4-7, pins in the bottom row as 8-9 and the circle enclosure as 0. Then:
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 - Headset Left
6 - Ground for Headset (grounds 0 and 6 seems to be connected in the subwofer but within the right satellite speaker they seem to be isolated with separate leads to sub)
7 - Power ON/OFF. When OFF or headset jack plugged then 0V. When ON and headset jack unplugged then 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 subwoofer you will need to implement:
- Power On/Off (switch between pins 8,7)
- Volume control 50k potentiometer (probably anything between 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 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 short any 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 VS4121 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 :)

Broken pin on wire


I am not familiar with this model ... I must ask ... Are these standard electronic plugs? RCA, Mini or micro phone? Mon or Stereo?

Two souces that pop into mind are Altec Lansing or Radio Shack.
