Hello! I have a Behringer EUROPOWER PMH 1000. But the power board burnt source. What do I will acquire another, or fixable?

Question edited for maker.

Running a 1/4" cable has no bearing unless you are trying to run a hundred yards of cable. Check your plugs wiring and connections to the unit. Here is the manual.

Oops! Smoke from on of those is not unusual, as behringer is notorious for bad solder joints and BAD Power supplies. Anyhow the amplifiers are "most likely" OK. but your powersupply is shot. My PMH 3000 did the exact same thing. And here is the bad news. Behringer is also notorious for the lack of assistance in case of problems and will advice you to have the unit repaired at an approved service point. If however you are ok with electronics you can have a go yourself, manuals are few and (very) far between. I have some diagrams and stuff, so if you need some sing out. I have 2, MX 3282A mixers, nothing but trouble! Sorry I can't help you any further, Good luck.

If you overload them the output MOSFETs fry and tend to take the circuit board and a few resistors out. They are fixable but it's a pain hat the board fries. The tracks need building up with wire so they can carry the necessary current (or any once they fry). Apart from that they are a decent Amp for little bucks and sound pretty good. They'll need micing for anything but smaller venues but the functions are really useful in getting a good sound for the buck.

GO ONLINE AND CHECK BEHRINGER EUROPOWER EXP3000 STEREO POWER AMP. YOU MAY GET SOME HELP THERE.

If you have manual, schematic is in the back pages. If not go to Behringers' site and download PDF (I believe it's under support)

If the board has not been burned up, one should troubleshhot the bad components.

If you need to replace it call Behringer at 1-425-672-0816. Have the board number including any revision number to get the Behringer actual part number. They will give you and incident number as well for you to call FullCompass who distributes the spare parts now. You can find FullCompass phone number via Google.

Probably the channel A went. If you are fortunate, the power supply is still OK. There are protection circuits for the speakers, however you MUST use speakers that are rated at over 400 Watts. If you use smaller ones, they can get blown. There is a weakness primarily on insulation for channel A and an arc between layers of a circuit board can wipe out several transistors and a zener diode and sometimes a metering resistor. Once this happens, have unit serviced before using it again as further damage can result.
ALSO PLEASE read my tip I posted on FIXYA regarding a grounding hazard when using Speakon to 1/4 inch speaker cables... essentially the barrel of the 1/4 inch jack of the A channel is the hot lead, NOT the tip for that channel.
