20 Most Recent Behringer B212D Powered Speaker (550 Watts, 1x12 in.) Questions & Answers

Hello,Eurolive Active speakers from Behringer suffers of bad power supply/Amp design, if you open up the back of your speaker you will probably find that the AC connector has a burnt or loose connection as well as a black spot, if not, check the power supply/power amp coils for cracked connections, let me know for improve help.

Try here... this is for a B212A but should be VERY close to the D version.

Contact [email protected] And ask for - Part #:W53-26000-22762 FUSEHOLDER;FH-B13HA $4.71 each.

Diodes probably fried. You made contact with the tip to ground. $3 or $4 part, but you probably fried more than one. $100 to $175 in labor for them to fully diagnose the problem.

I bought a 3rd B212D unit that powers on, has white noise, no music. I took the 8 screws off and discovered that the solder connection at the woofer had broken off. I surmise that either the unit was dropped or the speaker wire had gotten hot over the years. Since the amp had an open output from the break, the high output burned up as I heard a pop when I turned the volume up. . If your volume wasn't maxed out, you could check the wiring and make sure it is connected & save yourself some change!!!

The problem is bad high freq. IC TDA7293.There is no pasive crossover.

You are PROBABLY driving it too hard and the thermal cutout is activating. This is only a 12 inch speaker and should comfortably fill a 20 foot square room. If *********** could not stay in such a room, you are playing it too loud. Try reducing the volume by 3 DB and see how long it stays on. The specification on MOST of these powered speakers and speakers and amps in general are victims of "specsmanship"... that is false advertising to make sales. This size speaker is NOT applicable to outside venues for the most part. You could also try putting a fan blowing on the heatsink to keep it cooler as that might help.

D3 is shown as a 1N4148 small signal diode... I hate to say it, but if that diode blew you have MAJOR damage to other part(s). The minimum, with D3 fried, is that C10 is shorted causing the problem. If that C10 is not shorted, then high voltage must have been applied to the ring from that input jack frying R5 (1K), R6 (12k), C7 (1 nf )and IC1 which is a 4580 op amp. By the way C10 is a 47 pf cap that is likely surface mounted and most likelly shorted..

The parts cost I suspect would be about 1/2 of the new cost of the units... certainly by the time you add shipping cost... Find a competent repair shop.

To get the parts you would need to first call Behringer 1-425-672-0816 to get a part number and an incident number, then deal with FullCompass which distributes the Behringer parts.

Cost by replacing the amps would NOT be cost effective.

In looking at the schematic, assuming there was a voltage surge on input power, possibly the diodes and capacitors in the power supply are damaged if the fuse blew and was replaced.

If the speakers were powered by a different receptacle than the source feeding the audio to these was, ground bounce may have destroyed the first input stage.

You need to give us current symptoms so we can direct replacement of bad components.

Probable power supply issue. Check the + - rails.

You will need an oscilloscope and a good grounding in electronic servicing to attempt a repair. But, check the signal routing. Refer to the user manual.
