DJM-A9 + CDJ-3000X – ON AIR Display Issue

Hi everyone,

I'm experiencing a very strange issue with my new setup and I'm wondering if anyone has seen this before.

My setup:

  • DJM-A9 (firmware 1.22)
  • 2 × CDJ-3000X (latest firmware 1.40)
  • Netgear GS305 switch
  • PRO DJ LINK
  • Digital audio connections

The problem

When my CDJs are connected to channels 1 and 2, everything works perfectly.

However, when I move the exact same players to channels 2 and 3, the ON AIR Display no longer works correctly.

For example:

  • Raising channel 2 activates the wrong player's ON AIR indication.
  • Channel 3 does not trigger the ON AIR indication at all.
  • Audio works perfectly on every channel. The problem affects only the ON AIR Display.

Things I've already tried

  • Updated DJM-A9 to firmware 1.22
  • Updated both CDJ-3000X to firmware 1.40
  • Factory reset of the DJM-A9
  • ON AIR Display = ON on both CDJs
  • Manually assigned Player 1 and Player 2
  • Tested with and without USB drives and SD cards
  • Tested different Ethernet cables
  • Tested different digital cables
  • Tested different player/channel combinations
  • Restarted the complete system multiple times
  • Netgear GS305 switch
  • Crossfader Assign = THRU
  • Inputs set correctly to DIGITAL

Nothing changes.

Has anyone experienced this issue?

Can anyone with a DJM-A9 + CDJ-3000X setup test whether ON AIR Display works correctly when the players are connected to channels 2 and 3 (instead of 1 and 2)?

I'd really appreciate any feedback before sending the mixer for service.

Thanks!

Hi there,

If you change the players to channels 2 & 3, your assigned player numbers should reflect that too.

Can you check this and verify ?

Hello, I did the following: after turning on the CDJs, I manually changed their numbers to 2 and 3, and now everything works as it should. I restarted the CDJs, and the assignments were retained. Thank you! :)
