A Quick Worship Audio Set Up and Break Down, Part 1
Sep 10, 2013 10:58 AM, With Bennett Liles
And you’ve got to have a tough system that can take the wear and tear of being put up and taken down rapidly over and over so what did you go with for this?
We went with the JBL Vertec arrays. We have two sets. We have the 4888’s and the 4887’s. And we actually started with the 87’s as the smaller version, and every year we grow as the Bible study grows and hopefully we can get some 89’s pretty soon. But we started with 87’s, then we went to the 88’s, which I kind of call the mama version, and the papa version is the 89’s, and so we are getting there fairly quickly. [Timestamp: 6:10]
Yeah, so you’ve got one venue, the arena where everything is kind of vertically oriented with everybody up high, and the Kyle Field, the football stadium, where the coverage has to be a lot more spread out. But at any rate, it has to be simple and quick to set up so I think these JBL arrays are all powered units.
That’s correct. We decided on powered units because of the setup differences. And what happens is since they’re powered, we can use them as a front fill by themselves, or when we split it up we don’t need people to calculate OK, what’s the ohm load? Okay, which amps are used for this side, which amps are used for this side? With the powered units and the versatility of these line arrays, we can set them up any which way we want. We can stack three together. We can stack six together. And with some new line array frames that JBL’s coming out with, we can even intermingle 87’s, 88’s, 86’s, 89’s. And so just the combination, the versatility, the pin-outs and just the way they link together, it is just easy. And as I mentioned before, there are volunteers that are putting these together and I basically just have to manage and make sure the safety is there, but they just pop ‘em in, pin it with a number. We say six angle; we do the angles and we chart those angles out by using a Line Array Calculator which JBL provides for free, and with all those tools we have a successful event. [Timestamp: 7:35]
Well, although your crew may not all have a great deal of experience, once they get the routine down and have done it in both places a few times they can probably get it done OK. And you can customize these arrays I think. Do they have an interchangeable input unit on them somewhere?
That’s correct. So there’s different versions. There’s just the analog version, which is the DBX unit. That’s actually what we use now is the analog, and we have an external BSS processor in place. They also make a DPDA, which is with BSS integrated in each unit. We would love to get those, but just for the budget we decided to cut that out. But with the BSS units, you get EQ, compression and delay and all the processing power you want on each speaker. And with the separate BSS unit, like we have in our setup, you get the same power, but there is more involved as far as connecting to each speaker versus each array. So we do have that, but just for budget reasons we had to go with the analog unit. [Timestamp: 8:35]
Yeah, I guess the more stuff you already have in one box, the better it is when you’re in a big hurry to get it up and running.
That’s correct, yes.
So describe the built-in DrivePack amplifier module.
So the JBL power line arrays have a power amplifier built into the back and the power is by PowerCon, so we can sink all the PowerCon in the chain so that makes life easy. And then the other side has an input module, which you can pop and play and plug in and play. Like we can upgrade next year if the budget allows it. We can upgrade to the VSS module. And with that you can also link to each speaker, so if you want one line array to have the same signal, all you need is one drive line to the first unit and then it just chains together in a series from top to bottom. It makes life so easy. And on the DBX unit, you have an analog line control, which you can shade the speakers from top to bottom or the front gets a little quieter volume versus the back has the loudest volume. And with the new BSS input modules, you can actually link ‘em via internet – Ethernet – and basically with the Cat-5 cables, you can communicate directly to each BSS unit with a computer. And we can turn on and off each speaker, I can EQ it live, I can decide what each speaker needs to have as far as equalization. [Timestamp: 9:54]
That’s got to be just what you need when you go from a basketball arena to a football field with quick setup and strike.
Alright Wes, thanks for being here to give us a look at it. Wes Mathew, company manager from Puresound in Houston, Texas. In part two we’ll get more into how you do the quick setups for Breakaway Ministries. See you then.
Thank you so much. [Timestamp: 10:15]
