So I went to send a drum track to bus 7 and 8 on my console today and when I did I noticed that bus 8 sounded like ****. I pulled the patch, disconnected the cables on the back of the desk, moved module 16 into 8 and got the same sound... I tried hitting the reverse and trying the small fader thinking that the large fader was bad but I got the same thing.... WTF!!! I also tried sending signal to bus 16 (there is a 1-8 and 9-16 button) and that was fine.
I am at a loss, for now I am just not using that channel but this is no good.
