We've just bought a RML32AI mixer and started using it. But the problem is Mute All button activates itself all of a sudden. When the mixer is running and the Cue button in on, Meters +48, Main and Mute All buttons activate themselves. I mean Cue goes out, rest of them come and of course sound stops. It happens at least one time during the rehearsals and there is no common time to detect the problem. We don't know what to do now and appreciate your help.
Thanks in advance
