Pin connections on Spkr out jack

Anybody have the pin configuration and identifier for the speaker output jack on the subwoofer module? Also, are the 1/8" input jacks T.R.S. (balanced)or Mono (unbalanced)? I am going to use the sub and internal amps for a custom set-up. Thanks!

Installing an internal speaker on a Desk top pc mother board do you need to reconfigure your system.


Typically, the speaker is connected with 2 or 3 wires. The connector block should have a pin labled "SPKR" or "Speaker". From there, count three up and find a pin labeled "+5v". These two pins are typically separated by two ground pins.

So, the connection would be: spkr, gnd, gnd, +5v. The ground pins may, or may not be used depending on your design.

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 got a teac ag-v8060 audio/video surround receiver and I'm tryin to hook up some surrounsound speakers along with a jbl g cinema sub can you describe where the wires go in the back of receiver? The sub...


On the back of the receiver, there could be "pre out-subwoofer". If your subwoofer has the same type cable input, that would indicate it is a powered(amplified) sub. Connect those two. If subwoofer only has red/black speaker inputs, it is a passive sub, which means spkr signal runs thru it and then to your main left and right spkrs.. Run your receiver main or front spkr left (red/black) and right (red/black) to those corresponding sub inputs, and then sub spkr outputs to each of your main left/right spkrs..

For surround, on the back of the receiver, there should be spkr outputs (red/black) noted as "rear".

Just make sure red to red, and black to black.

Hope this is helpful.

How to run wires is series fof 3 subs


If they are single voice coil speakers (1 positive and 1 negative terminal on each speaker) then connect from amps' Positive output terminal to spkr. 1 positive terminal, THEN spkr. 1 neg. terminal to spkr. 2 positive terminal, THEN spkr. 2 negative terminal to spkr. 3 positive terminal, THEN spkr. 3 negative terminal to amps' negative output terminal.

That is 3 speakers wired in series. if each spkr is 2ohms, then you will have a total 6 ohm load. If 4 ohm spkrs., then a total 12 ohm load, if 8 ohm spkr., then a total 24 ohm load.

Be careful because amps do not like these odd ohm load totals. You might get away with a 6 ohm total load. Depends on the amp.

Sony Vaio VGN 'B series' - broken headphone jack.


Hi there, your question has two way you can fix it:
1) see speaker jack circiut on your motherboard, picture here

a0f7721.jpg
there are 5 pins to the jack socket, you may just find out 2 and 3 pin which is stereo audio output lines, and also need a ground 5 pin. then connect 3 wires go outside speaker. this way quite tough for you.
if you cannt do this way go next
2) find a USB audio card instead of onboard one. this is very easy.
reference here:

hope help you something fixed, please take a rating let me know how much helped you thanks! keep in touch your question

Subwoofer Connection: Speaker wire to Mono RCA


The easiest solution to use your subwoofer is to buy an amp for it. Any old stereo receiver from a garage sale will probably do just fine.
  1. Connect the mono RCA subwoofer output from your Sony with a 1xRCA-to-2xRCA splitter to both the left and right input of the cheap reciever's tape or aux input
  2. connect both speaker outputs of the cheap reciever to the speaker input on your subwoofer. make sure both black (-) outputs on the reciever connect to the black input on the sub, and the red outputs (+) on the reciever are both connected to the red input on the subwoofer.
  3. make sure the cheap receiver's volume is all the way down. turn your Sony up to about the loudest you'll listen to it. turn up the subwoofer amp until it's loud enough to sound good.
  4. leave the subwoofer amp alone, the Sony volume will all you ever need to touch from now on.

You can even now turn off your subwoofer / adjust the volume easily now!
