I've seen inside these mixers (euroracks) and they have a recurring problem.
Next to each op-amp there are small decoupling caps from the power supply rails to ground. These caps, due to 'cost constraints' have 1 volt of headroom- the rails are at 15 volts and the caps rated 16v.
This means they have about a 65% chance of failure.

Also, the psu. is connected via a connector. If you disconnect this and see if the psu powers up with a meter you can figure out if the psu is broken or if the circuit board is 'dragging it down'.

Hope that helps.

SOURCE: Pioneer DJM-600 black Professional DJ power on but not working!!

So you get power to the unit, but no sound coming out? How about through the headphones, do you get sound coming out of the headphones?

Are all the volumes and gains raised up? All the eq's are up? Check the back of the mixer, there is a master gain volume - where the connections are - make sure this is up also.

If nothing, then you'll need professional help at this point.

SOURCE: Behringer SL3242 Mixer has a noise problem.

It sounds like you have ground loops. This is noise generated by having interconnected equipment grounded at different physical locations. Especially a problem if you have a cable from your cable TV provider connected into your equipment.
Remove EVERY connection into and out of the mixer. Plug in headphones. Noise? If so, mixer needs repair. If not, re-connect equipment 1 piece at a time and assess for noise. If it slowly increases as you add connections you will need expert on-site help to fix it. If it is sudden, what was just connected is the source and steps need to be taken to lift the ground on the connection to that equipment.

How to connect behringer xenyx 1204usb mixer to a numark mixtrack pro II dj controller?


you have to tell your dj or studio program which device to use as output, but the dj controller doesn't have an audiocard so now i first have to search myself since my mixers have built in serato and another that annoying native i. No i'm just doing difficult while a numarkx5 stands in front of me and the main outputs go to your mixer and your usb is just for recording , but plug the mixer out in the mixer , main out in your monitors and calibrate the sound, but your studie or dj gear wants to know which channel to use and there fore you need to read the manual of your mixer and behringer. It's easy, but not from here.

PROBLEM WITH THE AUDIO OUT CHANNEL


It sounds like you may have a bad cable. The most common place for a small gauge cable (such as RCA, TPS, XLR, etc) with metal connectors to fail is in the stain relief which often fails to live up to its name. An easy way to check this is to grab the cable near the connector and wiggle it. If the sound crackles and changes volume levels suddenly then you may want to try a replacement cable. If the replacement doesn't help, you should use a contact cleaner such as "Blue Shower 2" that is approved for electronics use. Make sure your mixer is switched off and disconnected from its power source before using any cleaners to avoid any risk of electric shock. Apply the cleaner to all exposed output connectors on the mixer. Hope this cleans up your output prolems

Pioneer DJM 600 mixer keeps blowing ic 557 fuse on power supply board


I repair DJM 600 for many years. :) The reason for the burning of IC 557 (+8V H 600mA ) is invalid amplifier for headphones!!!
Replace IC 310 and IC 312 (in big mainboard), and replace
IC 557with original fuse 600mA
!!!!!CHECK YOUR HEADPHONES!!!!!! This is the cause burning amps.!!!!!

Piuoneer DJM600S feedback and cd input problems


Check List :
CD Deck 1 to Channel 1 CD Input
CD Deck 2 to Channel 2 CD Input
Mixer booth output to AMP's AUX or CD input.
use the BOOTH rather than the MASTER
even if you think you've done all these checks, check them again.
trust me I've been a DJ for 15 years & wired up **** loads of systems & still manage to ******* the wiring now & again lol.
you mite need to run an earth from your mixer to your amp.
One more thing, just out of interest you don't happen to have an amp with surround sound do you?
because if you do then switch the effects completely off this should sort it.

Feedback noise from mixer


Your mixer is already grounded, and does not need any additional grounding. It is grounded through the Power Cord.

Now, the feedback might be coming from one of the units you have connected to the mixer. The issue could also be the cable you are connecting to your recorder. Are you recording to a computer, or to some other external recorder (CDR / DVR / MDR, etc?) - try a different cable. Also try the different outputs on the mixer - you have 2 balanced line outputs you can record directly from. Don't use the RECORD OUT line, it's an unbalanced line, and if you want a good quality signal to record, your best bet is to use the XLR outputs. However, that might be connected to your amp or something.

What do you have going to the unit? Disconnect everything, and try by connecting each item 1 by 1, to eliminate where this feedback is coming from. Also, check for any ground loops that you might have, if you have a lot of equipment hooked up in your set up. (Educate yourself on Ground Loops)

If all else fails, get yourself a HUM ELIMINATOR.

Hi,wken i switch on my panasonic mixer grinder ,fire is coming it looks ike something is burning inside .Could u please let me know what happened?


What is a Panasonic Mixer Grinder?

What model?

If there is fire, and it smells like burning, DO NOT DO ANYTHING BUT POWER OFF and UNPLUG THE UNIT. You'll need professional help at this point. Something is obviously burnt inside.

Dj mixer problem


The fuse will do nothing in regards to protecting from such a voltage surge. The fuse is only good for minor power issues. Not stepping down the voltage is not a minor issue, and more than likely the transformer blew.

At this stage, you'll need to have it repaired by an service technician. This way they can test for any other damage to the unit.

Outputting high pitched sounds and master balance switch problem


Maybe the issue is not with your mixer. Maybe its with one of the units you connect to the mixer. Does this happen in all the channels?

If the service company could not duplicate the problem, then the problem might be somewhere else. Double check and replace your cables going to your amp, as well as the cables coming from your CD players and such.
