We don't seem to be able to get enough sound to fill a room with more than a couple dozen folks. I know the concept of using your lungs, I have done live theater for 15 years, but it doesn't allow me to be able to play the upright bass loud enough to be heard, not to mention the nylon string acoustic guitar. We are also short 2 inputs with our seperate system, having only 8. I am not sure what foldback means, but we can't hook a preamp to our system as it is, and now when we have monitors, they have to be at the same leval as the mains since they are hooked up in series.

I guess what you are saying is that I will not be able to simplify the set up much with another system.

WHat about recommending good lightweight speakers that can handle lows from the bass as well as the vocal highs and banjo? WOuld I be better off to buy a seperate bass amp and just run the bass seperate from the rest of the system?
