Indoor Performance question

WitchsMark

Hi good folks. We have been using our DRPA successfully for almost a year now, all of our gigs being outside facing an open field. I have just been using our DRPA with a Flat Response Setup that I did in the beginning using the Indoor AutoEQ method. We have a gig coming up on Oct.25th and it is indoors in a Church Hall. My local GC guy also does side jobs where he sets up clubs and what have you which almost always involves setting up a DRPA or better, and he told me that I would need to Auto-EQ my system upon setting up inside because playing inside will be greatly different than our Outside setup. Is this true?? I thought that was the point of getting the Flat Response to begin with. So if he is crazy, or just doesn't know, what would be the proper procedure for me setting up my system for Inside playing?? 3rd question: If you tweak the EQ, either GEQ or PEQ, for a given venue, does that throw the whole Gain Structure out of whack now??
Thanks in advance.

Hey Mark,
If your system is set up properly...you might have excellent results with no extra work..I recommend you try it.. BUT, just in case...Read my \"Auto EQ, how it's supposed to work\" in the FAQ section. If for no other reason, you have a perfect opportunity to see what the room is doing to the sound...BUT MAKE NO MISTAKE if you put the measurement mic on a stand in the room the resulting product will be BAD...The Low (below 170 hz) will be squashed... due to room modes... the highs will be compromised by reflections, which means, pick a spot, and some bands will be BOOSTED FULLY... those are reflected cancellations. I pick a spot back far enough for the horns to to meet, and if possible, put the mic on the ceiling (as close as possible see the pictures in the FAQ) If not,and the floor is clear. that will suffice, but again, use the same technique we talked about in the \"NEW indoor method\" I don't care what the local GC guru says, rooms CANNOT be EQ'ed...folow theses simple directions...
1. pick a spot for the speakers that focuses the sound on the people, and off the reflective surfaces
2. If subs are used, make certain that you avoid 3 1/2 -4 feet from ANY boundary...or the kick thud WILL disappear...
3. Before any equalization is used try moving the speakers around to get the best (least equalization used) product you can... as you can see this can be time consuming..and PAINFUL...YOU CAN MAKE IT WAAAAYYY worse sounding if you don't know what your doing.

Is the room pretty \"lively\"...and did I read that correctly..your playing in a CHURCH :shock: THAT must be interesting
Keep me informed...

Lol, yes we are playing for a church. It's a Universalist Unitarian church, we are playing their annual Witch's Ball that they hold, usually does well with an average of about 750 peoples that show up. If I do decide to tweek an EQ setting hear and there to suit the ears, is my Gain Structure gonna remain in tact?? And, again only if needed, ... which EQ would I adjust the GEQ or the PEQ?? I spent alot of time using the indoor method to flatten my DRPA as best as I could I would like to take advantage of that, so I would rather avoid the AutoEQ at the church.

IF you have PEQ's available, they are FAR more musical than the GEQ...

Witches ball in a church... too funny... :P

Remember, speaker placement and keeping the music ON THE PEOPLE and off the hard surfaces...will do more to help you keep things sounding good than ANY equalization!
