Frank,

Over the years I have discovered that the vast majority of the conventional and line array PA systems seem to provide the best audio quality when the master gain level is set between 60 and 70 percent. Then, by adjusting your mixer and or individuals instrument gains to a balanced setting, you will acquire the optimal quality and loudness needed for your audience.

Good luck,

Gary cool
