If the noise appears only when you rotate the control, there is dust inside it. With the amp disconnected from mains, rotate the volume control from min to max back and forth for about 30 times. See if this helps. This is not a definite solution, you maybe have to replace the potentiometer or spray some potentiometer cleaner. Good luck!

Behringer Eurolive B215B. Why does the bass cut in and out?


This could be caused by bad soldering on the controls. A quick touch with a soldering iron to the control terminals might solve the problem.

12" woofer not working


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!!!

I am currently having problems with our PA System. We use a Behringer PMP3000 Mixing Board, with a Peavey PV115 Speakers. We can't get them to reach the volume these speakers are ment for. We would run a...


The speakers are 8 ohm so you can probably get near the 400 Watt per side when connected to this mixer. You don't need bridge mode to get this and I would recommend not using it anyway. Whatever you do make sure the speakers don't get disconnected when running at high volumes as you will arc out the amp in the mixer... I know this as I fix them... I have two PMP5000's that I repaired. Lots of work to repair...

The feedback is NOT the fault of the mixer or speakers but instead of something picking up sound from the speakers and sending back to the mixer.

The mic must be well in back of the speakers (say at least 10 feet) to avoid this or you need to use anti-feedback hardware to avoid the problem or highly directional close talking mics. Reverberation off walls can also get back to mics and cause problem. I was able to use a wireless Peavey mic which seemed to disrupt the phase enough to never get into an oscillation even when in front of the speakers.

B300 speaker blowing mains fuse as soon as power applied


The power transformers in these and some other behringer speakers have a habit of short circuiting.
Good luck trying to get any details from behringer about spares or tech info..they act like they have something to hide...and maybe they do ;).
You can unscrew the amplifier part from the speaker and disconnect all leads except those 2 going to the power transformer..if it still blows the fuse then the transformer is history.

I recently bought a pair of b212A behringer speakers. when i turn the volume or/and bass past the half way point the clip (red light) begins flashing. Is this a problem and what does this mean


Clipping occurs when an amplifier is pushed to create a signal with more power than its power supply can produce. The red light flashing is warning you that your are overdriving the amplifier located in your speaker cabinets. This can cause damage to your amplifier and or your speakers. You should not allow the volume level to exceed clipping.

For Behringer B300 where is the ic 7815 and 7915


Test the regulator chips FIRST before ANY replacement. These chips are very reliable and the problem is LIKELY elsewhere.

The 7815 and 7915 ar 15 volt three terminal regulators in TO220 style packages. Three leads. The 7815 is plus 15 and the 7915 is minus 15.

CAREFUL as the input and ground pins are in different order between the two.

FIND the specs and picture with Googling the numbers.

These chips will be soldered in AND MAY be screwed or clamped to a heatsink OR just standing up from the board.
