Open Question

Do the fans on a Behringer PMP4000 fire up upon power up of the unit, or are they thermostatically controlled?

Working on half dead Behringer PMP400. Wondering if the fans are supposed to come on when the unit is powered on, or if they are thermostatically controlled. My reason for the inquiry is to deduce whether the PSU or amp board need to be changed. Tested out low voltage power to mixer board and all test out ok, the mixer lights all work fine and the board works fine with an external amp. The high voltage is not present for the amp board, but I hear that these switching PSU's can be tricky to diagnose as they require a load for them to actually switch into operating mode. With this in mind, I figure it can either be the amp board or the PSU. The fans seem to get powered from a winding on the same transformer as the hi voltage mains to the amp board, so if they are supposed to come on without thermostat, then can I safely assume the PSU is culprit. Does anyone know beyond a shadow of a doubt if the fans fire up on power-up?

Blank screen sounds like a fried thermosat. Abrupt outages can affect certain types of thermostats. Make a jumper wire and jump across R and G. See if you get any action from anywhere. If a fan or compressor kicks in you know you have a burned out thermosat...

It sounds like that unit is connected to a "power saving load controller" device from the power company. The power company can turn your unit on & off with a radio signal. If you manually activated contactor and unit ran. I would bet that the power company's device or the wiring connecting it is where the problem lies. Call the power company and have them check their device. If they tell you that the device has been tested remotely and is working fine. Explain to them that you can activate your unit manually and it works fine. They should not charge you to come out. Those "load controller devices" have a pretty good longevity record.

Testimonial: "Thank you. I was not aware that the power company had that ability. I will give them a call and ask about a test of their unit. Last year they sent me a postcard asking if I wanted to participate in their energy saving program. I declined but was not aware that they still had a device attached which could do it. I really hate surprises."

I'm Ziro. I need a part list for the main power supply board for behringer pmp4000 mixer, two transistors were removed from it and I need to know the part numbers of each in order to install them.


In my opinion, due to the physical appearance of pmp4000 and pmp3000 look the same, it will most likely also have a common circuit and parts list (at least, most).
Usually Behringer (and all the manufacturers), with the same series / sequence, using the same circuit, the difference is the number of channels only. You can compare the parts list on PMP3000 schematic, with your PMP4000.

Effects not working on Behringer PMP4000 monitor


Normally, on mixers, Effects do NOT go to Monitors.
What you have to do is
(check if there is a control for "EFF to MON" before)....
*Make a cable bridge from EFF OUT to any channel of your inputs.
*Now you can send the EFX to monitors as you would any signal.
Be mostly happy....

Beringer pmp4000 no sound out and lights flashing


Sounds like you have blown one or more of the outputs. You need to take it to a repair shop.

One of the amp fans stopped running, and eventually lost one whole side and it was crackling on the side that was working


When a fan quits the system has failed, turn it off before things fry. I do not know the unit but it sounds llike serious problems. Unless you are expereienced in electronics take it to an appropriate repair facility.

Pmp4000 unit. can i designate different effects to different channels at the same time?


only 2 effects can be used at a time. you assign the effects in your lil digital section in the master part of the board by turning the black knobs so the lit up numbers change to the effect you want then push the black button to lock it in. at which 2 of your aux's ( the last 2 i think its 5 and 6 ) control the SEND to your EFFECTS and the fader below the selections control the amount of effects goes into the MIX.

I just purchased A behringer PMP4000. It has built in effects. When I follow the steps to add fx , as soon as I start turning up the fx send, It sounds like sweeping wind through the mains. How do I use...


Check the FX to main level to make sure it is not too high. Also check the main FX fader level. Try turning each of these down and see if that corrects the issue. The FX fader should control the volume level of the FX globally (mon sends as well as main outs), and the FX to main should only affect the mains output. Make sure FX to mon1 and FX to mon2 are turned all the way down.
Also check what FX program your using and that the FX IN button is depressed, try starting w/ #10 (small room) and see how that sounds.
