Hi everybody, I have a problem with my Xone DB4 too

On the channel 2 & 3 the input selector is not able to switch to all input.

Exemple : I move from 2 to 3 to 4 ... 3 do not activate LED is off ans sound also.

If I power on the mixer with selector on 3 it works, but if I move the selector .. same issue.

Exactly the same on channel 2 with the 4 input.

Thks !!!!

Bonjour!

If you set the selector switches before turning on power does the mixer work correctly after turning on?

Is this a matter of burnt LED light on the selector matrix?
Or can you still meter audio on your 3rd channel when selected in the matrix (regardless of led on or not)?

No, the LED is OK .. The LED and the Audio does not work together...
If I power on the DB4 with selector on 3 .. the LED and the sound is OK ...

Suppose you power ON with the INPUT SELECT on 3, does everything work?
Now with power still ON, does everything work when you select 4?

Yes when I select 4 it works .. but I cannot come back to input 3 .. I must power off .. select 3 .. and power on
