When I use 4 cdj 2000's I link them together using a Netgear dual speed hub, the DS104, it enables all the decks to talk to each other and access a USB Harddrive or Stick or mem card that's plugged into any one of the 4 decks.

Pioneers more expensive mixers like the DJM 900 Nexus and the DJM 2000 nexus have built in hubs for networking 4 CDJs and to a computer which again enables each deck to see each other and the computer to access files but the network connection from the mixer to the computer does not allow HID with Traktor (no idea about serato as never used it but it works fine with rekordbox though)

I find nightclubs tend to be very strict with what they will allow you to do (unless you are a really big name DJ)
I have had some clubs even refuse me plug a laptop into their CDJs so I could use Traktor (so I always carry 2 usb sticks and a case of CDs with me just in case)

Thanks for the info Sarah, very helpful! Sounds like things work well configured that way, which I look forward to giving a try.

Any place that has CDJ2000/2000nexus' and hasn't got them networked really shouldn't be in business- it is the main selling point of them and an integral feature. Then again, having seen the standard of some lazy engineers it doesn't surprise me tbh - those sort of people and places give the good ones a bad name!

Don't forget that the mixer should also be plugged into the hub, so you get the 'on air' display; the CDJ jog wheel lights up red if you have that channels fader up ( if they are numbered correctly- otherwise you get odd things like channel 1 being up and CDJ 4 goes red!)

The DJM900 nexus does not - it has a single ethernet port, so it requires an external hub.

The DJM-2000 - despite being crap - does have ethernet sockets for 4 CDJS and 2 computers, so no external hub is required.

Thanks for that, never networked a 900 nexus so was unaware it was a single port but was aware it had the capability of being networked.

Personally, having the 'on air' display on the CDJs was never a feature I cared for. I can see why it would be advantageous but I have set my CDJ2000s to flash 90 seconds before the end of a track so I know which one is 'on air' and have the cue button on the channel of the next CDJ I am going to mix in lit on the mixer, I do have the decks numbered though which helps when I use Traktor and its remix decks.

As I have never networked my CDJs to a mixer, am I right to assume, that the fader start on the DJM 2000, would automaticly start the deck on that channel when you slide it up?

A lot of the clubs I have played in that have CDJ 2000s or CDJ 900s have not had them networked, I always carry a cable in my bag just in case, I never ask if I can plug it in anymore because most of the time I got told no, I just set up the first track to mix in and whilst its playing, pop in the Ethernet cable and then select my 2nd track.
If another DJ is following me, I leave it plugged in, I leave my bag in the booth as well so I can have a drink and a dance and collect the cable and my bag at the end of the night.
