North Carolina’s Elon University needed a complete sound system upgrade for its revered Whitley Auditorium, and they called in Audio & Light to handle the job with speakers from DAS Audio. Jim Hoyle is back to wrap up his talk about the project and how the university operates the new system, coming right up on the SVC Podcast.
SVC:Jim, thanks for being back with us for part 2 on the SVC Podcast and the complete sound system upgrade at Elon University’s Whitley Auditorium. Last time we talked about how you got the DAS Variant Series speaker array installed and checked out and how you managed to arrange the time to do that between events. On this one, I wanted to get more into the rest of the sound system in there and how they operate it. So what sorts of other gear do they use in the sound system in Whitley Auditorium?
Well, besides the Variant speaker array, they have a Sound Craft FX 16 console. It’s just a small format console mounted in a rolling case that is usually sitting on the lip of the balcony so an operator can be in the room and experience the sound as the audience would. There is also a position in a booth where the rolling rack can be moved into a booth and the console be plugged in there and it’s behind glass and removed and it’s very rarely used there. In addition to the FX 16 speaker processors, we use the DAS digital processor to control the system it is the DSP 2060 A. [Timestamp: 1:54]
What do they have as far as mics? I know they have some events in there that have to mic’d for sure.
Yes, the microphone collection in that room is very basic; there’s a Shure SM57s, Shure S58s, but the university has lots of microphones spread out all over campus that they have access to and some wireless broad too. There was Shure SLX wireless systems, handheld, and lavaliers. [Timestamp: 2:17]
OK and the Shure SLX is a very popular item. We use it on our university campus, too.
I wouldn’t think that you would have a whole lot of RF issues in that kind of place.
No, but there is a lot of wireless on campus, so we have to be very careful about frequencies. We keep a list of all the frequencies we’re using on campus and we make sure that we’re not stepping on any toes. [Timestamp: 2:36]
I think we went over this in Part 1 a little bit. When we got to how the speaker enclosures are powered you were saying something about having some power installed up there for those things.
Did you have any sort of power or grounding issues to work out up there on those?
No, all the power for the sound system is pulled off one panel, which was in the tech booth in the rear of the balcony and from there it’s an easy pull up into the attic space and down to where the array hangs. It was very easy to get power in and out of the booth and everywhere we needed it so no there were no grounding issues. It all worked all very well. [Timestamp: 3:10]
And how are you controlling the power up there? Controlling it remotely I assume.
Yes, there’s a middle Atlantic AC relay system. So one button turns the entire system on and off in the proper order. [Timestamp: 3:22]
OK and the mobile mixer that I guess can be placed just about anywhere they want it. How do they do the job of cabling that? Is that something that’s permanently in place or do they sort of roll something out to connect it to the amps up above?
Yes, all of the mic lines and signal lines from the stage run from the stage to the booth and at the booth they split. And from there there’s a mass connector in the booth and then there’s a split and another mass connector mounted on the face of the balcony wall where the mixer can be plugged in there as well. [Timestamp: 3:52]
So there’s a mass connector on the end of a short snake coming out of the console that can plug in either in the booth or at the front of the balcony, but most of the time, it stays at the front of the balcony. [Timestamp: 4:03]
