Does anybody have a schematic for the separate power supply unit integrated into the Behringer Europort EPA150 Portable PA System?
If it sits in between the incoming live connection & the mains input to the PSU then it will most likely be an NTC. That's a resistor with a Negative Temp Coefficient. At room temp it's a high enough resistance so as to limit the inrush / surge current at switch on. Then as it warms up from use the resistance goes down & the unit works normally. Something like this is worth a try... https://www.ebay.co.uk/itm/2-x-NTC-5D-9-Inrush-Current-Limiter-Power-Thermistor-5-ohm-3Amp-ref-403/282807213327?hash=item41d89f9d0f:g:R5EAAOSwMgdX0vHs

Behringer Xenyx 1222FX won't power on, only phantom power
Since the phantom power is working, it's unlikely to be hte problem at the transformer. You have to locate the ground wire of the mixer (ususally the lower end of the faders, or the ground from one of the audio connectors). Using your voltmeter you must find one point providing +15Volts and another one providing -15Volts at each of the input stages. I think that the problem is that one (or both) of these voltages are absent. Mention that the +15 and the -15 volts are between the ground and the apropriate pin at the input stages. In case you will not locate the +/-15Volts, or they are 0Volts, post me back for further directions.
In case of a problem or clarification, don't hesitate to post me a reply.
If you are satisfied, accept my solution.
Thanks and regards

The B207 MP3 player sucks

I ran a MP3 cleanup program
MP3VAL and it helped but
I am still getting 'Reading'
and then ERROR and I also
tried another completely new B207

ANY other mp3 device works!!

No sound from speakers how to fix the problem
Assuming that you've checked the fuse, and the lights come on...1) Can you hear any "hiss" from the speakers at all? 2) What have you tried to input into the device? (guitars, keyboards, mics, etc.)3) Have you reset all buttons to "basic" mode? Let me know, and we'll go from there...

Where to connect my Subwoofer
This is NOT convenient with the 2000 unit...ASSUMING you subwoofer has mid and high frequency cutoff built in, what you should do is to mix the two preamp signals in a small mixer and send those to a POWERED subwoofer OR to an amplifier that is driving the subwoofer.

Hearing an air sound through speaker
Im having the same problem too. when i'm turning on the speaker, without having plugged some cable or jack on it, it sounds like blowing air (or like a storm).

Hello!
I have a
Often teh power supply fails because of other problems. Unless the board has flame damage the parts that are defective can be replaced... Getting some of the parts that are special can take time. Most of the components are available at many sources however. The SPS400 power supply can be repaired.
Here is link to schematic that should have the SPS400 as well as the rest of the PMH1000 on it.
