Voltage djm 400

You do not need to replace anything, buy or have a stepdown transformer

of at least 200 watts rating.

Step-down transformer specs:

220V input

110V output

However , there are other DJM400 versions that have a built in 220V

input. Have a tech to guide you.

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...

My audio mixer sound craft epm-8 is not working , some part like R1 burned.kindly tell me the value of R1, and the correct output voltageof cn-2

If the part burned, it did it for a reason. Likely something has shorted, probably an electrolytic cap unless there was a liquid spill. You will need a complete schematic. I haven't found one yet.

I need to know the value of the Resistor "R1" in

Let us use a bit of logic to resolve this... I have an Axiom but it would be a lot of screws to take out to get to the part... so let us think about this. The resistor value starts with a "1" and we know it is 5% tolerance (gold). we know the resistor burnt up with likely 5 volts on it... Value could be 1000 ohms, however the voltages present (12 volts max) would NOT have burned up a resistor of 1000 ohms. The USB area is mostly 5 volts and across 100 ohms is only a quarter watt... not enough to really burn up a resistor... First thing is to MEASURE that the resistor s open... in spite of being burned, it MAY still be OK... these resistors now usually either open or remain close to their value. The resistor ALSO may be a fusible resistor intended to act as a fuse... Is the resistor open or not? is it near a resistance with a "1" as the first digit? If it is not open I suspect it is not all of the problem. In that case, look for a burned circuit trace on the board. If it is open, then MEASURE the voltage across the resistor with the power applied. If you find 5 volts, then it MIGHT be a 10 ohm used to limit the USB current to 500ma. Get back to me with your findings... I have unraveled many of these things...

Part for mp3000 position R1 37

Your description is inadequate for me to give you help. R1? and what is the 37? and is this on a PMP3000?

Here is schematic for a PMP3000 if that will help:

There are multiple files compressed... you can use the RAR decompression without paying.
At the website above, scroll down and click on "get manual" to download the service manual. Ignore the other download links.

I ordered the whole dj 350 W set from the US. Problem is, im still a young upcoming DJ and this is my first shopping experience with any DJ equipment. So i didnt really know anything about the voltage...

See where the power cord of the CDJ350 goes in , there will be a sticker stating the working voltage of the device. US models usually do not have this switch you are talking about ( south east Asian models do ). All you can do is find out the wattage of the CDJ --- will be written next to the 120V / ??W. W indicates the watts of power consumed. Add up all the W's of all the 120V equipment you have purchased and add another 25% to it. Then go to a electronic store and purchase a 220 to 120volt step down transformer.
Example one CDJ is 35w and you have 2 nos + you have a Pioneer DJ mixer (from US ) which consumes 50W. You should go and buy 35 x 2=70w + 50w =120w + 30w ( 25% ) = 150WATTS step down transformer.
There is no problem buying an over powered transformer like 200watts . Never underpowered .

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 a pioneer djm mixer 400,I hooked it up to 2cdj mk1002. I want to run them through my pioneer reciever.which is a vsx having a problem.IT works okay,if i run the cd player directly to cd...

If your CD player works hooked up to the DJ board, then try hooking the line out of the board into a auxiliary in or line in in or record in on your receiver using the appropriate cables.Try the CD in first and if there is too much signal then use the CD/Tape in. You need to match the output signal of your board to the input signal of your amp. Hope this helps.

How to connect my qqualizer to my djm pioneer 400 mixer

Use the stereo master outs from the DJM into the A and B Inputs of the EQ (you'll need 2 phono to Jack or 2 phono to XLR cables) then from the A and B Outputs of the EQ to the power amp/ speakers, etc (you'll need jack or XLR cables depending on what is powereing your speakers)
