Replace 4 pin plug on Behringer V-Amp2 PSU

I have a replacement plug for the Behringer PSU (a dual AC voltage external type; 20v 200ma & 11v 800ma ). The problem being, the origional plug was pulled off & lost so i have nothing for comparison to refit the new plug. I therefore need the pin out config for the respective voltages.
Any help on this matter would be greatly appreciated.
Maybe someone has a PSU they could just meter up for me ?

    Thanks robotek, i did initially contact Behringer who just gave me the email address of their official UK "out of warranty " repair agent, who in turn said that they didn't have the information & then tried to sell me a new psu !
    Hope your contact is better than the official channels. Looking forward to your post.
    Thanks again,

    Is the PDF for the pin layout available somewhere?

  • Anonymous May 23, 2009

    Seems like a common problem. I would also like to get the pinout, I have a spare 4-pin DIN plug.

I know that this is way late, but the pin out for the V-Amp 2 is simple. I just repaired mine after having bent a pin. First, the 4-pin replacement plug is VERY easy to find. It is the same plug as a simple S-Video cable. Then, looking at the pins from the front, as if you were the female plug, the order is BLUE (top left pin), WHITE (top right pin), BROWN (bottom left pin), and BLACK (bottom right pin). Rather than mess with the possibility of bending another pin, I re-soldered the colored wires to the S-Video plug pins, then inserted the plug into the V-Amp. Then, I merely used strips of common duct tape to secure the plug permanently to the female plug after removing the housing case. After several strips and layers, I returned the unit to the housing, tightened it down and it holds the new connection tight, as if it was made to be that way.

Hi mgriff66

I have scoured the net to get the info you need, but came up empty handed. I would take the back off the unit and work out what connections are what from tracing it out to the power supply. If you are not up with electronics, then that may not be an option. I have emailed (ref 080528-000007) my Behringer contact to get the info for you. Will post it back here shortly.

How to test an LCD TV or monitor PSU and inverter


Before proceeding I assume you have technical training along with the multimeter. A full testing must be done with power on, and for safety reason must not be done by an untrained user.

The tip contains only general indications. The reader is supposed to have the training to apply in practice the testing method below.

If there is no power at all, then the responsible is almost always the PSU.

When there is no power, test AC in to PSU. If there is no AC in (read volts, or read ohms on power cable), that means that the power cord must be replaced.

If there is AC in, then test the PSU section near to AC input. You always find a resistor or a fuse in there . Check if it has blown.
After that you test the rest of PSU component. If there is no power at all , and problem is not power cord, it is often possible to spot at a glance a leaky or bulged capacitor.

If there is power, but the monitor stays in standby, then te PSU is forced to low voltage only by controller board. This happens when a fault had been detected.

In this case testing the PSU becomes more complicate. The technician must locate the control lines from controller board. This control lines operate at lower PSU voltage (often +5V), and turn on higher voltages on PSU board.

The inverter may use for example a +20V line from PSU. The +20V line is turned on by the controller board, closing a +5V control line to PSU. When PSU is in standby mode, the technician testing the PSU must bridge the +5V line with the PSU low +5V circuit, and test if the +20V line to the inverter gets turned on.

As explained this kind of test must not be done by the unexperienced user, as the chance to waste the unit beyond repair is high, and there are also many safety concerns.

After testing the PSU, next part to test will be the inverter board.

The inverter is tested reading DC voltage in from controller board, and AC out to back light system.
The inverter is an high voltage board, remember, safety first when testing AC circuit.

If the inverter has no DC from controller, then test PSU, if PSU is OK, and inverter has still no DC in when PSU line to inverter is on, then replace controller board.
If the inverter has DC in, and no AC out, then replace the inverter.
If the inverter has DC in and AC out when higher DC voltage to inverter is turned on, then test at component level the main controller board, and if present test LCD controller.

Swapped power supply and not sure if i connected everything

This guide shows a lot of the possibilities for any PC.
Basically there are only three important connections: The main ATX connector - usually 24 pin, plugs into motherboard at the edge near the memory slots [it's a 24 pin on your m/b]; the CPU power - plugs into the motherboard, 4 pin (square) [your m/b has the square 4-pin type, I think it's near the 'M' of the MS-7623 label], or 8 pin (4 x 2) on newer computers - and the hard drive power, usually a flattish 15-way connector (SATA) [your computer also has IDE capability, four in line pin connectors]. Your graphics card if present may need external power from your PSU, but seeing as you're not sure you've connected everything up, I'm assuming you don't have a graphics card.
The connectors are keyed so you can't put them in the wrong way round; do not force them, but they may be a bit stiff.
It would help if you told us the model of your PSU.
Be certain that the voltage input selector, if present, on the back (outside) of your PSU is set to the correct voltage.

Black screen

can you see any POST messages when you first turn it on?
ie amount of ram / discs etc..if not try connecting an external
monitor it might be the screen malfunctioning
also is your psu generating the correct voltage ( 18-20v)
if you can , remove ( for 20secs then replace) the internal 5v battery to reset the bios..remove the battery pack and power first though
bottom line is..your mobo could be f****ed or your bios corrupt
best of luck

Lenovo laptop(8932) will go into a sleep like mode (you can still see the screen, very dim) when plugged into ac adaptor. Doesn't do it with battery power. Changed system board, power adaptor - no...

Good Day Psmith!

It looks like the AC adaptor is not making the right supply voltage needed for your laptop.

If you have a multi tester, you can test your ac adaptor to see if it has stable 20V voltage output supply needed for the laptop to make it work.

Set your tester to DC range. Plug the ac adaptor to your wall socket. Hold the other end of the ac adaptor (the one you connect to your laptop. Insert the red (positive) lead into the center of the adapter pin, then touch the black (negative) lead to the outside metal part of the pin.

Read the display in your tester. If the adapter is working properly, the meter should read between 19 to 20 volts of the rating. If the adapter is faulty, the meter will read below 18volts.

If that would be the case, I'm afraid you will need to replace your ac adaptor.

You can purchase online a replacement ac adaptor for lenovo 8932.

I have a Behringer xenyx 802 audio mixer and have lost the power supply. I tried to buy a replacement, but cannot find any in stock. I'm very resourceful and thought I'd make one. The spec sheet calls for...

No, you can't just jump the pins together. The power supply in the mixer needs two separate 18-volt AC inputs because it makes two supply voltages, +15 and -15 volts.

The external supply is just a potted 36-volt transformer with a center-tapped secondary. I bought an open-box Behringer (not your model, but similar) that was missing its supply, and found this transformer which works fine. (I actually did find a couple of sources for a replacement Behringer supply, but it cost more than I paid for the mixer!) Just connect the three output leads to the appropriate places on the mixer's PC board. In mine, I removed the original input connector and soldered a pigtail with a 3-pin connector from Radio Shack to the PC lands, then attached the matching plug to the transformer leads. You'll also need to provide an enclosure of some kind to prevent contact with the line voltage input to the transformer and to protect the thing if you carry it around.

I cant plug my 120v input vamp2 power adapter into a 110v output voltage regulator its dont works

I don't understand why you are plugging this into a 110 volt regulator.. If by chance you are trying to run this from 220 volt power, you DO NOT use a regulator or a converter intended to run hair driers and appliances. You need to use a step-down transformer from 220 to 110 or 240 to 120.
The V\Amp2 is a switching regulator and it will NOT like to be run from another switching regulator such as found in those cheap appliance type convertors.

Here is the type you need:

Power Supply V-amp 2 Pinout Diagram

Don't have the pin lay out but the power supply is a transformer with two isolated secondaries. The blue & brown leads come from the 20VAC 200mA and the black & white 11VAC @ 800mA windings. I used two doorbell transformers (and a rheostat for the 11VAC section). The reason for two transformers is the secondaries MUST be isolated or something will fry!fb818bb.jpg
