this is my first post on this forum. I'm not a native english speaker so sorry in advance for any bad grammar
I'm having problems with xlr outputs on my new Grandstage 73. There is a strange sound coming out and it happened two times since I've bought it. For most of the time an xlr output is working allright. First I tried to reboot it several times and it didn't work. Then I tried switching a ground/lift switch and it also didn't helped. Then I just used 1/4 inch output with a DI box and it worked normaly.
I'm asking if someone have experienced this issue or is my unit bad and needs replacement?
Here is an audio clip of this strange alien sound coming out of xlr outputs:
