I HAVE AN ALTEC LANSING AC5 295 SPEAKER SYSTEM. I NEED A NEW RIGHT SPEAKER AND 8 PIN CONNECTOR CABLE.

1121? Altec Lansing used to be good speakers, but not any more.

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

mini din Connectors
no ,,you can get you one

Altec Lansing ATP 3 has 7 pin mini-DIN connector for Right Satellite. You will find that at electronic hardware store. WebRepOverall ratingThis site has no rating(not enough votes)

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 :)

can anyone help me with the Altec Lansing VS4121 2.1 Channel i need the wiring diagram of 9 pin cable i broke it. please mail me the layout at [email protected]

Yes!!! Check the voltage size, get a docking station 30 pin adapter, which has the same output and input voltage size. and thats gonna solve it for you ok.

-->The pin cable goes from the control speaker to the base. Red connector in this picture.

 

--> The 1/8" mono goes from the other speaker to the control speaker. White mark in the control speaker.

 

--> the SW has 2 inputs (m-m 1/8" stereo cables) 1 comes from the audio out of your sound card,

   the other is the subw input, you can connect this if your sound card has that output.

 

 

 

Good luck

 

Rate my response please.

 

Philips DVP 3256 has 6 outputs which takes in RCA connectors
Altec lansing VS3251 has 3 STEREO outputs.
Buy 3 nos of STEREO (female) to RCA (male) cables
1. Connect the Altec's green wire to first stereo-to-RCA cable. RCA ends to DVP 3256's Front left and Front right
2. Connect the Altec's black wire to second stereo-to-RCA cable. RCA ends to DVP 3256's Rear left and Rear right
3. Connect the Altec's orange wire to third stereo-to-RCA cable. RCA ends to DVP 3256's Centre/Sub woofer. Interchange RCA ends if the Subwoofer sounds dull.

Good Luck

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.
