Prime 4 loss of sound from xlr outpout

Denon Prime 4

Firmware Version: 1.6.0

My main right XLR output has become very quiet compared to the left output.

Hello @Sammunition, Welcome to the forum.

Did You checked Your master output panning?

Thanks for the welcome. How do I check my master output panning? The panning for each of the 4 decks is set to thru. Is that what you mean or is there another setting? Cheers.

PAN (left/right balance) There is no Master PAN on Prime 4???
