Ok, i just bought this powered sub from goodwill. it was $3!!! IT was also half off day!!. So it was $1.50. I need to know what the name of the plugg is for this sub.
Got to [Link: freewebs.com] to get a pic of the problem. Please tell me the name and if they even make it anymore. your help would be appreciated.

whatever

ok...sorry for the whatever...now that the page will load, which it wouldn't when I posted the whatever...

you need to look for a DIN type connector, although it may or may not be anything related to that....it sure looks like a DIN connector to me...so once you've figured out if it will fit, you need to know what the pinout is...

have you done a google search for the manufacturer of the subwoofer, and more importantly, any technical documents, forums or sites that might pertain to it?

Do a search for DIN

Yes, i have done a search for the manufacturer. The sub is by crescendo by midland. It needs to buy and AC current. just to let you know.

DIN connectors have standards for use with audio, but they are occasionally used for power, and there is no particular standard that I have ever heard of for what pins are used for power, and there is definitely no way that a connector will define what voltage should be present.

I think you have a very low-power subwoofer that is powered by an external power supply. If you figure out how to power it, you will get your money's worth, but you paid $1.50 for it...

My son works at a college where he brought home a similar item, without a power cord. We did some analysis and figured out it might put out about ten watts, and take us a couple of hours to figure out how to make it work.... It sounded sort of funny when it landed after we literally gave it the heave-ho.

Stumped, whatever you do, don't send 120 volts into that connector! When used as a power plug, it's always the output of a power supply, a.k.a., wall wart.

You might never be able to know the proper voltage/current/polarity, but opening the unit might be your only hope. If there are no labels, that's where I'd start.

If the driver is decent, you might consider wiring a pair of terminals directly to it, and use it as a non-powered sub. Good luck!

For $1.50 I'd hook that sucker up 220v and let it fly. Worst case, a smoking end table.

YEA! 220v! IT will play really loud for a very short time.

Ok, thank you for your help, i just want to know if people still make the cords as a power supply and where i can get it. thank you. Oh yeah, the sub max wattage output is 15 watts.

Stumped, the point is that, while it may be possible to find 100 different power supplies that come with a DIN plug, we still need to know the voltage and current requirements. Is there a model number, or a label that shows the volts and amps (or milliamps) that is needed?

No, there is no label that tells me anything about it. I am thinking bout getting to more sets of computer speakers, 1 with bass/sub output, and one just to hook the sub up to. Can you tell me if that will work?please i need to knoe so i know what to do or if i'm out $1.50

You are not out $1.50.

You have learned some things and gained some helpful but often sarcastic friends. All for $1.50! Money well spent, I'd say.

It says "A/C In" so we can bet that 110 V goes somewhere. About the only way to go from here would be to open it up and see where the leads go. I'm betting that two of the leads go into a nice, big rectifier. If we're lucky, the circuit board is even labeled.

The other thing to do is determine with of the leads has continuity with ground.

This is a DIN 5 connector (not a mini-DIN - that's your keyboard/mouse connector).

I've seen a number of power supplies with these as DC inputs (most recently on the first generation of Motorola cable modems), but never AC before. The power supplies should be around - I'd call the old electronics place in town and ask if they have a DIN-5 power supply.

I can't beleive that there is no brand or model number anywhere on the unit.

Sounds like a sub for a computer system.. it would be a midiland would it?

Yes, 110 V goes in somewhere, but NOT on that connector. That is a low-voltage connector, originally used in Europe for line inputs and outputs. I have seen on old B & O preamp with zero RCA jacks. All the connectors were DINs.

I think one of the posts said something about 15 watts. If 110 V went in here and went directly to a nice, big, rectifier, you would have around 150 V DC on the output of that rectifier, which is WAY too high a voltage for any audio amp in the range of 15 watts.

But 12 volts at 1.25 amps is 15 watts, well within the range of voltage and amperage that a separate corded black-plastic-box type power supply would put out. That wattage fits right in with the type of connector and the other comments made above that it is used for low voltage.

The fact that it takes an AC input actually only says that they put the rectifiers and filters inside the box. Maybe they found it cheaper to go this way instead of having a DC power supply.


I couldn't believe it either when I saw the one my son had, that I referred to above. No labels at all.
