SOURCE: Need Behringer Eurorack mixer power supply connector

Those were used for mic connectors at one time,,, they are related to the Amp 91-MC3F family of connectors and those are out of production and they are demanding $20 to $50 for one connector.

That is a ridiculous price and I would be tempted to swap out the connector for a more available design.

On eBay item 250401122616 is one but they want $13 pus $11 shipping which is a rip off.

These were used on some OLD CD radio mics.

SOURCE: I have a behringer bx4500h.

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.

SOURCE: how o u hook up

In order for this to work properly it must be inserted between the last pre-amp stage and the power amp. Can you please update this with the mixer that you are using? With the make and model of the mixer, I can provide you with a connection description. Since each mixer will have different labeling and options, it is not possible for me to accurately describe the connections without hte make and model.

Thanks,
Dan

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)

What are the sound effects provided on the Behringer epa150 PA?


The effects should be the same as the EPA900 unit. Get the brochure here and look for "Effects Table." Hope this helps! http://www.behringer.com/assets/EPA900_P0431_M_EN.pdf

Behringer sx3242fx not working .i need circuit diagram .


Behringer will not release schematics unless you are an authorized service agent... however, sometimes you can make do with the few schematics floating around... What is the problem with the unit? They typically use a switching power supply and the schematics of those aree usually similar enough to repair them.

Behringer DDm4000 purchased in 2009. Over 2 years happy usage, but now it's got some major issues! The power supply seems corrupted as after about 2 hours use it maxes out the signal (ouch) and all...


Behringer is stingy about schematics... however here is one for their DJX700 which MAY have a similar power supply to yours:

http://elektrotanya.com/behringer_djx700-professional_sch.pdf/download.html

Scroll down to "get manual" and click to download... IGNORE other download links.
On page 9 near the lower right corner is the simple power supply, minus the transformer but showing the rectifier diodes, filter caps, and the three terminal regulators. These regulators have a thermal shutdown feature so if they seem to run VERY hot they might cause your problem. Common things are failing electrolytic filter caps. Behringer also uses switching power supplies in some gear and I have schematics of examples of those as well... but peak in your unit and see what type supply you have.

There are two resistors 310-3 10R on the power supply of the Europower pmp 5000, i need to know if it is 330k or 330om.


The schematic for the power supply does NOT show resistors in the 310-3... Where are these in the circuit... IF THESE happen to be the gate drive resistors for the IGBT's they are 33 ohms. If you have hasd a failure in this area there are other parts that typically get destroyed, including one or both the speedup diodes at the same gates; Here is the complete PMP5000 schematic:

http://elektrotanya.com/behringer_europower-p0569_hca2400_sps1000_dpx_pmp-1280s_5000_sch.pdf/download.html

Power surge has blown components at input to the power supply unit SMPSU17. I need schematic to help identify the correct replacement components. John at Topaz Repair Limerick.


Behringer re-uses a lot of design... you might look at page 2 of this download:

http://elektrotanya.com/behringer_pmh100.pdf/download.html

Scroll down to "Get Manual" and click to download. On page 2 is the SPS400 power supply which is one of the smaller switching supplies they use. You may find the schematic is close, possibly they de-populate it as a smaller supply. When repaired, start the supply for testing with a 60 watt light bulb in series with the power input. Use an isolation transformer for troubleshooting for safety.

B212D powered speakers internal amps damaged by power surge in our home. Can they be replaced with new amps and what would cost be. johnssale@gmail.com


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.

Fan doesn't when 6pin cable between power supply and PA, is plugged in, however fan works when disconnected from PA board


The fan control receives two signals from the HCA2400 power amp module. Pin 4 is labelled POS+ and pin 5 is labelled POS-.
These two interact with T14,T15,T16,T17, and finally T7 which gates a -21 volt power to the fan.
From the schematic, it appears that if POS- is more positive than about 20 vollts negative the fan will be held off. It appears that the POS+ signal controls the speed and as it goes more positive, this would DECREASE the speed. Pots VR2 and VR3 are used to set these thresholds and I do not have setup instructions for those... I would be very careful about adjusting them without the procedure. . HOWEVER, first thing is to verify that you have -21 volts DC on pin 2 of the fan connector. With the HCA2400 disconnected, the POS- will drift to -21 volts and POS+ should drift to somewhere around -6 to -8 volts judging from the schematic.
Trying to trace these two signals on the HCA2400 is very difficult and the schematic does not show where they go... I did find that pin 5 does go to one of the thermistors on the heat sink labeled R2 and one side of R1 goes to pin 3 which is -12 volts by tracing an HCA2400 I have open. Pin 4 seems to go to the other side of R2 so then the R2 thermistor connects between POS+ and POS-.
The room temp (71F) resistance of R2 seems to be about 112 ohms and rises with increasing temp. It appears that R1 is involved with a signal sent to the power supply called OFF which probably shuts down the supply if the HCA2400 gets too hot... so R1 thermistor on the HCA2400 would have nothing to do with the fan... I can;t verify that R2 does more than connect to pins 4 and 5 of the connector... there may be biasing resistors on the HCA2400... I would find it odd that VR2 and VR3 would both be connected in series effectively with R2 thermistor... so I suspect there are additional biasing on the HCA2400 that one of the tweek pots conrols the ability to run and the other controls the speed above that... Please note that the resistance measurements of R2 are made on an HCA2400 that a hacker all but destroyed...

I have Behringer pmp 2000 mixer but it burned my fuse. How can I buy it?


If the fuse blew do NOT replace it till the unit is serviced or you will burn up more components. These units will blow out from a minimum of three to 30 components when they blow.

There is weak insulation between layers of the power amp circuit board and the arcing destroys a minimum of three transistors and often many more components on the power supply board as well.

I have repaired several of these and it is a lot of work. The power amp module can be had for about $175 but it often takes out the power supply as well.
