We just moved to IEM and an Aviom system. I purchased a pair of Atrio M5 earbuds since most of the reviews I saw said that they had a pretty good bass response. My problem is that I seem to get lost in the mix whenever any other instruments are playing. I have to crank my bass volume way up in order to hear my notes when other instruments are playing. I have tried to turn everyone else down, but the bass still sounds muffled and disconnected. Tonight at rehearsal, I even switched to a floor monitor. It wasn't as bad, but the bass seemed to get lost in the mix. Any suggestions I can give our sound guy? He hasn't been doing this long, so right now he is guessing.
