Well, we hooked up the amp and it is WONDERFUL!

We have the gain somewhat lower then normal, to compensate for overpowering the speakers. The nice thing is, the speakers don't hiss anymore! Before we were running the outputs of the main board as 2 mic inputs of a powered board, and from that to our speakers. Now, however, main out is going to the amp, and it is silent now.

We are using the old soundboard/amp as a monitor for the keyboard, and listening to the difference between the two is amazing.
