You need to replace the potentiometer with the broken shaft. You can open the unit and try to get a part number or go to Behringer parts to get an exact replacement. The pot must be matched for value, taper, and mounting and shaft dimensions.

SOURCE: I've got a Behringer Ultrabass Bb410 1200w 4x10

The cabinet is listed as a 4 ohm unit.

We would exoect to see four, 4 ohm speakers in series parallel or four 16 ohm speakers in parallel.

If teh unit seems to rattle, first put an audio oscillator into it and sweep the frequency. It is common for grilles and also logos attached to them to rattle.

Open the unit and power each speaker the same way individually for a test.

I suspect you will find either the grille or mounting hardware is actually doing the rattling OR possibly the wires inside are vibrating.

If the sound is a scratchy buzz, then the speaker(s) have probably had voicecoils damaged by overheating.

In this case, buy 4 new speakers and replace all. It is not likely to find replacements for the Buggera brand they put in these cabinets. Also the word on the web about that brand of speaker is not very good.

SOURCE: Behringer's Ultrabass BXL3000 - problem with the

You will PROBABLY find the 4 screws on the sides that screw into the chassis and then get frustrated that it will not come out... MANY of the Behringer things HIDE the other screws as the ones holding the handle... The trick is to get at them... The plastic end covers over the handle have ridges that snap under a metal plate that is over the handle. Carefully pry out the plastic near the handle to release these ridges... pry SIDEWAYS a bit... The ridges snap into small cutouts in the metal... what a pain these are. Use a small 1/4 inch screwdriver with blade vertical right where the handle comes out to bend the plastic outward... Dont reach in very far as the blade will catch the metal... just far enough to catch the plastic cover edge... it is scary. The two handle screws usually go into nut-plates that are a part of the amp chassis.

The DI consists of two sections of an op amp and is truly driven differentally. There usually is a couple of 120 ohm series resistors and a couple of hf bypass caps near the connectors

Can I add a 4ohm 4x10 speaker cabinet to the lineout port in back of the Behringer 3000A


No. The line out is at line level, not amplified to speaker level. Yu can run a powered cabinet, but not a passive one.

Impute jack on a kick back type cabinet. need to remove amp from cabinet to repair.


Very simple. Remove all black screws at top and sides of cabinet. Gently slide the amp unit out (towards rear). Done! :)
Don't be alarmed if you have to "tug" on it a bit. This is normal. Just don't try to "FORCE" it out.

Not functioning..


I would check it with a different instrument cable AND bass guitar. If you end up with the same results, it's a thermal issue with the amp and will require factory authorized repair. The amp heats up and the intermittent component starts failing....more heat, more failure. It's not an easy fix and your Behringer repair shop will have their work cut out for them with this repair.

Foot switch appears to be wired backwards. The Shape pedal turns on the UtraBass and the UltraBass pedal turns on the Shape (Channel 2).


Foot pedals are usually NOT interchangeable... The correct footswitch would come with the amp so be sure it says Behringer on on the footswitch. Apparently some sellers have foisted off VOX footswitches which may not work with the Berhinger.

Rattle/vibration in the horn of my 4x10 cabinet


Open cabinet and look for loose wiring. You may have blown the tweeter horn if nothing is loose.

The input jack on the back of my behringer cabinet and the active input jack in the front of head have both cracked and separated. The Quarter inch cords for each respective input jack do not stay in. What...


The jacks have to be replaced. If you are not adept at repair, best to take it to a shop for the repair. Do NOT use the unit till repaired. If the jack shorts you may damage your amplifier.

My Behringer Ultrabass BX600 has a very loud, constant hum. I tried a new power cord, and speaker along with checking the internal parts for a burn spot and tight fit to no avail.


It is likely the power amp chip has shorted. This puts the unregulated dc into the speaker and you will hear the hum. DO NOT operate this way as you can burn up the speaker. You will find that the LM3886 chip on the heatsink has failed. They are about $7.30 from Digikey. They come in two lead bent versions. Make sure to get the correct version and use heat sink grease wheen installing.

I have a behringer bx4500h. pre-amp board has a noticeable hum that also reacts to tone controls. I need a schematic to fix it. Can you direct me to a schematic of this unit?


Behinger normally doesn't give schematics... However here is a link to a BX1200 schematic at a foreign site. OFTEN they use the same circuitry within a series of equipment.

http://elektrotanya.com/behringer_bx1200_sch.zip/download.html

Note it is a zipped file of both F and H revisions.

Please note that the symptoms you describe are NOT usually something you will find in the preamp, but rather in the interconnections. It appears that the BX1200 uses TRS inputs at the jacks... not sure what your BX4500 does...

Make sure ALL your interconnected equipment is powered from the SAME receptacle to avoid ground loops and hum. Use balanced lines everywhere possible.
