I was worried about having enough imputs-Keyboard, two vocals and a vocal using a vocalizer. Tech support assured me there would be no problem. I plugged my keyboard in the base of the Model 11 and ended up having 4/5 unused. I could not believe the sound. It was great. After using it once, I sold my Mackie set. It used to be if it wasn't heavy, it was no good. Not so with your system. Everywhere we sing, we have to show off the system we are using. Again THANKS for a great system.
