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.

Tap and fx buttons are stuck hi my name is john haill i am blind and own a djm 800 i my mum was cleaning my gear and she used polish and now there stuck

Use some CRC226 around them to break the polish residue and lube them. It should only take a little. CRC226 is available at Home Depot in the electrical dept. It is plastic safe.

I have a djm 400 and it has started producing a buzzing sound through the speakers. I can take the same speaker cables from the djm 400 and hook them up to my backup mixer and the buzzing goes away. What...

Since it works with your other mixer, the DJM400 is probably fine. You have a ground loop.

Make sure ALL, and I do mean ALL... (re-read that if there is any confusion) interconnected equipment WILL BE powered from the same receptacle or source. If speakers or amps are powered from one place and the DJM is from the other end of the room you likely have a ground loop and you can ex[ect buzzing. Run extension cords alongside the audio leads if necessaryy to carry power from where the amps or speakers are plugged in back to the DJM400 and ANY pther connected equipment.

Just bought DJM 800 mixer and the screen went out within 5 mins. The display stayed off and never came back. any ideas

This is likely a power supply problem. If under warranty have it repaired right away. Unless you have electronic repair skills, this is not a DIY project.

My DJM 400 power button does not stay on, when I hold in the power button it does have power, but does not switch to stay on. Any quick fixes for this? Thank you.

The only "fix" for this is to replace the power switch. The internal latch has broken. I have seen this a few times. You can get the part from Pioneer directly. Contact them and request the power switch for your specific model. They may also request the serial number as there were a few variants of this model.

One Output low on DJM 400

This may not be the correct solution, but have you checked the switches on the back of the DJM-400 to see if one output is set to "PHONO" mode?

Pioneer DJM-400 mixer turns on, but channels aren't working

could be a few things , what have you tried to trouble shoot the problem ?
My steps would be ;
check all leads (even if you KNOW u pluged them in)
check the gain is set corectly .
check the line phono slectors are set to what ever you have you leads pluged into on the back of the mixer ( there is 4 red and white RCA plugs , 2 for phono,2 for line CDJs shold be using line )
if you are using digital cables to conect your CDJs , on the back on the mixer there is a small switch marked "CD or digital" make sure that is sleceted "digital " . if ur not using digital cables make sure it is on "CD" .
the info iv put here is based on the DJM-800 so your mixer my not have some of these featers as iv never used a 400 . hope this helps dued . check out for more tricks and tips . Pratices'N'enjoy !
