Enhanced console burns the speakers at the main output.

is one: Behringer Europower Pmp 2000 When I connect a speaker to one of the main back outputs, it comes out with a lot of esteem, tension and burns the speakers. here the rear panel with its 3 outputs what voltage should come out of these outputs? What can be? On the front panel it has other outputs and they are all good. These burned a speaker and when I try to plug another makes a very strong blow ("TAC") the cone and unplug. it makes a bit of a burning smell on the tmb speaker. I tried a 4ohm speaker. And the last one I have is 3ohm. I bought it used and it was like that. Thank you!

Hello, you should check your output transistors or integrated output because there is a crossing, check putting a voltmeter at the output which will mark the source voltage, it is normal that there should be no dc or ac voltage. , that's why your speakers are burning you.

Hello! thanks for the reply. the right and left give me 62.9 and 62.5v respectively. bridge gives 0.6v

Hello, it is too much if you are totally crossed with the source, that voltage is that of the source, check the mentioned components, output transistors, electrolytic.

Hi Sricagno, there is another detail that you should know, if the amplifier has a relay in the protection audio output you should check, because sometimes this when making contact creates a resistance due to the poor contacts and makes the output transistors overheat And burn them.

Check the audio outputs either with transistors or integrated, also electrolytic filters, one or more must be shorted and causing an output voltage that burns your speakers.

Your audio output is short, check as the companion says check the amplification mosfet

if you have vcd instead of vca which is the one that has to go because it is a sine signal then you have bad outputs the most likely to be the transistors
