Question about Behringer Europower Pmp5000 Powered Mixer Pmp5000

1 Answer

Behringer PMP5000 Mixer. Connected a speakerOn cable to Output A while device was ON. Went to do the same thing on Output B and heard a spark. Turned off the mixer. Now, it will not come on. Checked the main fuse, it is ok. The other 3 fuses are ok also. Tried to run the board as Mixer only by disconnecting the two 3-pin and small 6-pin cables from the sps1000/02 board. Still no power to the mixer. Checked for the presence of +15v and -15v on pins 1and 2 at X4 on sps1000/02, nothing. Mistake I made was not to have verified that the 1/4 connection on the speaker end was properly done. What damage have I caused and how can I fix this?

Chances are you've blown the output transistors. Speakon connectors cannot short out but jack connectors can and if it was not inserted properly you'll have presented a dead short to your powered mixer. In any event it is really bad idea to connect anything when it's switched on. If you're really lucky replacing the output stage (which will probably be dead short on the transistors) and re-adjusting the bias should sort you out.

SOURCE: Behringer PMP5000. The Powered Output B dead

Make sure the three position slide switch is set correctly for the stereo usage, that is NOT the bridged OR the Mon mode.

MAKE SURE the pan pots are set to middle as they control the spit of the audio to the two channels.

This is a class "D" amplifier (switching) and there really isn't any fuse for a single channel.

MAKE SURE your speakon connections are good by swapping your speaker cables.

I repaired my unit and had to do that without schematics... Behringer will not give them out. Mine had a severe arc-over on one side power amp taking out about ten transistors and diodes and one swithcing regulator chip. Had to cut out the "cancer" of the burned board.

This unit uses a complementary output stage that is made up of one transistor on one side and a pair in parallel on the other. This drives the inductor/capacitor filter... I think the switching frequency is between 100KHz and 1 MHz as I recall. All those transistors were gonzo. It also fried the main power switching transistors in the power supply, several smaller transistors, diodes, and the switching regulator chip.
Also two 10 ohm power resistors were fried. They soft start this unit by charging the main caps via two resistors that limit the inrush current.
A small switching supply has to come up first before the main supply which sends the DC to the amp section.

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: Behringer XENYX 1622FX, won't power on. Phantom power works(?)

After reviewing the schematic, I don't understand how the Phantom power can REMAIN on with the power switch off... this CANNOT occur except for what energy is left in the 48 volt supply filter cap... This might last for minutes after the fuse went... UNLESS you have devices connected which are backfeeding the 48 volts. (which would be a disaster)

The 48 volts, +/- 12 volts and +/- 15 volts and the +5 volts ALL come from the SAME switching power supply. I suspect one of the filter caps went or the primary switching regulator a TDP245Y chip.

You should ONLY work on the line side of this using an ISOLATION transformer since the line side has lethal voltages.

To do testing, one replaces the fuse and puts a 60 Watt light bulb in series with the hot side of the inout line. The lamp "acts" as a resetable fuse and limits the current for testing. When all is well again, the lamp will remain out with the power flowing through it.

The D1 diode bridge and C7 input rectifier and filter are first things to check. You can do those with an ohmmeter.

I will caution you to ALWAYS power any and all equipment from the SAME power source. Plugging in devices from across the room will set up ground loops and any ground fault will fry equipment.

SOURCE: Hello; I have a used Behringer pmp5000 mixer. The

Without knowing how you have your monitors configured it is hard to analyze what you have posted.

In brief, SW3 on the schematic that selects MAIN L and MAIN R in the upper position, MAIN and MONITOR in the middle, and bridged in the lower is used to configure the internal amps.

In the upper position, the amp power outputs come from the mixed stereo bus and are simultaneously controlled as a stereo signal by the MAIN slider.

In the middle position MAIN and MONITOR, the left amp receives the signal from the mix bus and is controlled by the MAIN slider. The MONITOR output from the other side of the power amp is controlled ONLY by possibly the "MONO" slider.

The schematics are hard to decode and what is needed is a signal flow diagram.

For my uses, I don't try to use splitting the power amps between mains and monitor but prefer to use the mains together with SW3 in the upper position (Note your 27 may be refering to the user manual designation for same switch). I then use another small amp from the 1/4 inch MONITOR jacks whcih are under control of the MONITOR sliders.
Please note that the MIX for these two MONITOR channels is controlled by the MON1 and MON2 knobs for each channel.

SOURCE: Behringer XENYX 2442FX Mixer. The power light

You have likely lost one, probably the +15 volt power supply... This is possibly a shorted component or a short on the circuit board causing this. It takes some skills at troubleshooting to find this. Sometimes using a thermal imaging camera will show hot spot... other times you have to search with a millivoltmeter. The rude solo light is driven by an op amp that uses both polarities of 15 volts and to turn it on it pulls negative... Hence I suspect the +15 is missing.

Yes, it can be repaired. Likely at least the output transistors are fried, possibly the drivers are too. Possible other components like resistors gone, too. Needs somebody that knows amps.

Europower PMP5000, In the Front Panel there is a Main 1 & Main 2 output, can I connect both to 2 Amplifiers so I have four independent outputs or 2 Stereo outputs? Can I Use these two outputs + mon 1...


Yes, you can use both the main1 and main2. They are independently driven and please note that they are PSUEDO balanced drives... that is the cold side of the balanced line is NOT driven as a complement, but is merely returned to signal ground by a 120 ohm resistor. This CAN cause hum problems or noise pickup depending on the connected equipment and ground loops. Best to run this into amps/speakers thaat have TRUE balanced inputs and also keep the power source the same for all devices.

HOW DO I CONNECT 2 SPEAKERS TO THE MIXER


Unpowered (passive) speakers connect to the Speakon connectors on the back of the unit. Powered speakers or amplified ones connect to the mains output L/R connectors (1/4 inch) near the upper edge of the panel.

New to the mixer world. i have a dicontinued pmp5000. can't get the bridge mode to work


You require a special cable with the Speakon copnnector wired a special way. Refer to your user manual for the correct pin connections to use bridged mode and then put the slide switch in the position closest to the effects display.

Refer to figure 4.6 on page 10 and figure 4.7 showing the connection for bridge mode.

NOTE: you cannot go below 8 ohm speaker on the bridge mode... that USUALLY means a singl speaker of 8 ohms... you CANNOT parallel two 8 ohm speakers.

The single speaker cable will plug into the "B" output connector. Remember bothe the barrel and the tip of the connector if using 1/4 inch plugs is HOT and grounding either inadvertently will fry the amp.

My pmp6000 wont work in mon1/ mono mode. I have one speskon channel going to two mains and the other to two monitors Can't get sound.


OK... from the schematics it appears that when in mon1/mono mode you use ONLY the MON1 gain controls, including the channel MON1's and the MON1 slider. Make sure you have each of those turned up as needed. In this mode, MON2,s and the MON2 slider are unused. The MONO slider controls the MAIN output.

My Behringer Europower Pmp5000 Powered Mixer blew one of my speakers and then it burnt out one of the outputs.


Probably the channel A went. If you are fortunate, the power supply is still OK. There are protection circuits for the speakers, however you MUST use speakers that are rated at over 400 Watts. If you use smaller ones, they can get blown. There is a weakness primarily on insulation for channel A and an arc between layers of a circuit board can wipe out several transistors and a zener diode and sometimes a metering resistor. Once this happens, have unit serviced before using it again as further damage can result.
ALSO PLEASE read my tip I posted on FIXYA regarding a grounding hazard when using Speakon to 1/4 inch speaker cables... essentially the barrel of the 1/4 inch jack of the A channel is the hot lead, NOT the tip for that channel.

Suddenly the monitor one output jack has no sound. If I turn the Monitor one slider all the way up I can hear a very low sound with distortion. The monitor output works fine.


Make sure the appropriate channel rotary knob MON1 knob is turned up for the channels you want into MON1. ALSO test other channels if they can be sent to MON1. The MON jacks are TRS with the tip as the hot and the sleeve as resistor to ground.

Hopefully you have used good practice and have ALWAYS powered whatever you are driving from the MON1 out from the same receptacle as the PMP5000. If not, ground bounce MAY have destroyed the driver in thee PMP5000. They USUALLY don't tell you these things in the user manuals, so it is up to us electricaal engineers to educate.

FIRST plug in a set of headphones and see if sound comes out (it will only be one side and fairly low volume, usually the left). If it does, then cabling and whatever amp you have for the MON1 has a problem. I have schematics and can help you troubleshoot a bit.

Also PLEASE read the tip I have posted on here about a grounding hazard of the A channel when using Speakon to 1/4 inch cables.

How to set up my power mixer?


First thing is to read my tip regarding a speaker polarity hazard of the PMP mixers.

Second thing is to VERIFY speaker cables are properly connected.

If you are using in stereo mode set the slider switch to MAIN L/Main R.

describing all possible configurations is not possible on here, but read your manual with this. If you don't have a manual, download one for free.

I have a Pmp5000 889406987784 Eurowpower PMP5000 1200-Watt 20-Channel Mixer and Speaker Output A has no output. What has happened?


Usual problem is the Channel A amplifier has burned and blown the switching transistors. Usually an internal board arc occurs and unless very skilled at board work of clearing the burned area and replacing the components you are better to replace the HCA2400 amplifier module... about $160

Setting up a Behringer PMP5000


You can do the effect via the "POWER AMP INSERT" jacks.

Use TRS interconnects to yout effects unit.

If the effects unit does not have TRS type bi-directional in/out ports, you MAY need to make special cables to connect the units. Refer to figure 4.5 on page 9 of your PMP5000 user manual for INSERT connections.
