This is becoming a recurring problem for me when I switch my 4000G on in the morning, today the problem persists. In the past i've tried swapping mix amp cards with the RBS, this did fix things for a while, but the problem does keep returning. It suggests to me it's not a problem with the mix amp cards.....
I'm not that techy but general fault finding sensibilities aren't too bad.
It has nothing to do with mix bus inserts or bus comp.
Any help appreciated.
Thanks
