By following the steps of this editorial you void your warranty. When your warranty. is still valid this may only be done by an official Pioneer Service Center.

Check to get in contact with the Pioneer Head Office in your country. They can give you detailed information who to call.

Faders are just like tires from a car. No matter how good they are, once every so much kilometers you're tires ware off and you'll need to replace them. The DJM-600's faders are very easy replaceable if you know what you need to do. The following is a guideline how to do a proper replacement. This should only be done when no warranty is valid and by people that have some kind of technical knowledgement.

When ordering faders remember : Each channel has it's own part number for the fader. This is because the PCB (Print Circuit Board) that comes with the fader differs for each channel. Off course these faders could also be ordered as single part without the PCB part, but it only saves you a few Euro's and costs you a lot more time to replace.

To replace the Crossfader you can check -> This Topic
Although part numbers could be changed when time passes. These numbers are correct for the last few years (2006). Use this to order a certain fader WITH PCB:

  •   Main Assy : DWG 1520
  •   Channel 1 : DWG 1521
  •   Channel 2 : DWG 1522
  •   Channel 3 : DWG 1523
  •   Channel 4 : DWG 1524
  •   Channel/Main Fader component : DCV 1010 (without PCB, needs soldering, all channels use the same component on a different PCB)


1. Remove Fader Knobs

When pulling the knobs straight from the mixer you can tear them of quit easy.

You can wash the knobs with water and soap if you want to, just let them dry for some hours before you put them back !

2. Unscrew the Front Panel

Unscrew the 4 screws to loosen the Panel that covers the fader area. The 4 blacks screws are located in the corners of the Panel, in this image there are red circles around them.

3. Remove the Front Panel

Once all the screws are loose and removed you can lift the panel, following the shown direction is the easiest way.

Watch for the black felt that keeps dust from falling into the faders through the Panel. This should later be put back the way as shown by the arrows, but in opposite order.

4. Get new fader

When you buy a new fader you have to take care of the following:

The lock in the connection terminal that makes the final connection to the flat cable inside the mixer is closed when it leaves the factory.

You have to open it first. Just pull at both sides at the same time directly and straight from the component like the arrows indicate on the image.
Open the lock of the new Fader
5. Check the lock

This is what the lock looks like when you've got it opened. You'll see a row of squares from left to right. When the lock isn't removed far enough this looks different.

6. Unscrew the fader

Each fader is held in it's place by 2 gold colored screws that are located at the top and bottom of each fader.

The rings on each screw are a certain type of protection so that the fader lasts longer. These rings absorbe most of the force that useally comes to the front and bottom part of the fader when moving it up and down.

The force that is used on the fader is directed into the chassis of the mixer and not to the top and bottom of the Fader itself.
Unscrew the 2 screws for each fader
7. Remove the fader

Follow the direction of the arrows. By first moving the fader to the side, then pulling it up you can remove the fader.

This example only shows the movements for the fader of Channel 1 but this is the same for Channel 3 and the Mains fader. Faders 2 and 4 move first to the left and than upwards.
Get the fader out by following the arrows
8. Open lock and pull fader of straight

When you've got the fader out of it's position you can open the lock of the fader and pull the flat cable straight out.

This should go very smooth, if you feel some sort of resistance you probably haven't opened the lock on both sides or you might not have opened it enough.
Open lock and pull the fader straight from the wires
9. Fader Start

The faders for Channel 1 and 2 both have a special arm to activate the Fader Start function wich needs to be used on the new fader. This arm slides between an opto coupler to transform the movement of the fader into an on/off switch for the Fader Start.

You see the opto-coupler as a black U-shaped part on the PCB. By using the electrical way instead of a micro-switch you don't feel a click when the fader is opened and closed.
10. Remove the Fader Start Arm

You need to remove these from your old faders if you put them on the new once because these are NOT included when you purchase a new fader.
11. Insert the flat cable into the Fader

You have to do this very carefully. If you do this the first time right it saves you lots of trouble. The wires from the flat cable are not massive so you bend them quit easy.

The holes in the connection terminal on the Fader Assy are just the right size, using to much solder will make it almost impossible to get it right again without ordering a new flat cable.

When the flat cable is on it's place you can close the lock of the connection terminal on the Fader Assy to make the connection completer.
12. If necessary : do the other faders

You can handle the other faders the same way if you need to replace more faders.

Faders of channel 1 and 2 both have a flat cable with 9 wires. Channels 3 and 4 both only need a 6-wires flat cable.

On the picture you see the faders of channel 2, 3 and 4 unscrewed and waiting replacement.
13. Put it back together

When you're done with all the Channel or Main Faders that needed to be replaced you'll have to put the Front Panel back again and put all the fader knobs back.

mare als je die 'Fader Knobs' gaat verwijderen en je steekt ze er terug op zitten die dan niet te los?

Nee hoor, maar natuurlijk zitten ze wel beter vast als je ze nog nooit hebt verwijderd Winking my eye

Mijn DJM 600 is van 2001 en mijn fadersnummers zijn niet hetzeflde als in deze topic weergegeven. Ik heb :

master DWG-1521 --> 124k
CH1 DWG-1521 --> 123k
CH2 DWG-1522 --> 123k
CH3 DWG-1524 --> 123k
CH4 DWG-1524 --> 123k

Zou ik deze nummers respecteren om te bestellen of zou ik de nummers hierboven vermeld bestellen ?

Vriendelijk bedankt.
