A thousand seat auditorium is large enough to warrant a delay line. The center cluster is a good addition for theater making the voices come from the stage but not NEEDED. I would keep it tho. I think focusing more on teaching people to use this system would yield more bang than replacing it. The system sounds like a system that you would find in a university theater of that size. Also, teaching people to use it will be educational.

I agree with the need for the delay and the center cluster. I don't mind those because that's all initial set up. For atually mixing a live show though, who wants to mess with trying to balance the system between two front speakers that put out the music and then 2 center clusters, 11 front fills, and 3 balcony fills all putting out the vocals. Although I have not had the chance to mix a show on the system as is yet, it seems as though it would be very difficult to balance it out. It also seems that the overall system output would be very low unless you wanted the vocals totally overpowering.
These should be set up such that the rear fills run a signal from the center or a summed front/center. The stage lip should be on an aux so you just dont have to use it. and the Mains, center should be setup bussed so you can just bus everything to whichever system you want. You should be able to just send everything to the speakers you want without doing anything but pressing a few buttons. Also, even in theater you will want some vocals in the mains and a little more in the center (usually +6dB)

I work in a theater in The Netherlands, and we have a comparable system consisting of an Axys source set, Axys source centre cluster, 4 Axys U-12 balcony fills and 6 Axys Tx-86 frontfills. We use two XTA DP200 DSP's for EQ-ing and delaying.
I always operate the system using the left and right outputs of our K3 mixer for left and right stack, and the mono output for the rest. All levels are set by the XTA, and delays are set as well. I operate the K3 in a special fader mode, so that the left master fader handles left and right, and the right faders operates the mono ouput. Some others prefer a maxtix output or a group out.
This is very simple to operate. You can use the summed L+R signal for the mono ouput, but for speech or to let the sound come from the middle for the entire audience, you just set the mono level somewhat higher.
