    The xti Amp was purchased used from someone locally - very good deal, so I got it.

    I found some used CPL27s and will be purchasing some new ones as well. Overall, my cost is not much higher than I was planning on.

    The 260 arrived today. I'll hook it up tomorrow.

    I am planning on running a pair of Speakon cables to two of the monitors (one left and one right), and then coming off the terminals of the speakon-fed speakers into the terminals of the other speakers. I ran this past someone from Community tech support and they thought it would be fine. I had planned on getting some cheap monitors but felt that having extra speakers around for redundancy wouldn't be a bad thing.

    My goal here is to give everyone in the audience the same experience. This is not always possible in a production where the front row sees details those in the back row don't see but it is very important to me that everyone hear everything as good as we can get it.

    No delay necessary? Should I even try it or do you think we'll be OK without it? The speakers will be spaced somewhere between 30-40 feet.

    I'll post again once everything's in place. I have learned so much from everyone here. Thank you, thank you, thank you. It's amazing how someone who had done quite a bit of technical work back in High School knew so little.

    I guess the point I was making about the speaker wire is.. that if you WERE going to delay the speakers, you would have to run one wire to each speaker...you wouldn't be able to daisy chain them like you are talking about. A delay setup would be ...one out put to one channel of an amp and that going to each speaker.. If your going to do it that way you could get by with ONLY the 260, and you could control the house and monitor speakers easily with just the 260...

    I'm using a 260 and a DRPA because the mix feeding into the monitors is different than the house mix.

    Yes, I'll be running individual wires from amps to the house speakers.

    I strongly recommend 1 speaker per 1 side of amp on 1 of all 6 DR260 outputs. For this reason. Feed back is most prone from the speakers at the front, less from line 2 and even less from line 3. The audience in the front section don't need as much reinforcement since they get volume from the stage. Lines 2 & 3 can be boosted quite a bit before feedback.
    Use the AFS to find problems then fix them with the PEQ for line #1. If you have a 9 db cut at 2K for #1, then go ahead and make a 6db cut there on #2, and a 3db Cut on #3. The latter 2 may not need adjustments at all and will depend on whether it affects the overall sound, but I was being conceptual.
    I think delay will be useful since Line #2 also gets sound from Line #1 and #3 get sound from #1 & #2 (mostly).

    Oops, I forgot to send this 2 hrs ago.

    If you ran a mono output you could control everything with the 260, but with it being a play you probably will need some stereo effects stage left or right.

    You should make some speaker snakes with short, med and long runs. Or better, a six conductor cable from rack to a junction box then a 4 conductor to junction and finally a 2 conductor. Or whatever you come up with. There are a million ways.
