Do not use mic in with loud shows, it will not be able to take it..use the line in jack. I dont really use r/o anymore..but when i did i found 195hz was nice to my ears. You may like another setting..try a few settings at home in front of the stereo ( volume up obviously) just make sure you run line in not mic in. Also at the show set your levels manually..dont ever use the auto function. Theres alot of things to do/not do...look ouer some of the other threads. gd lk 2 u.
