Worship: A Tailored AV Bid for New Construction, Part 1

And what did you out in the narthex area? Are you doing 70V?
We’re doing 70V speakers out in the overflow meeting area that are the QSC AcousticDesign 5 in-ceiling speakers, shallow can. [Timestamp: 8:49]

I guess you can put any kind of feed you want to out there in case it’s closed off&emdashor I don’t know&emdashhow much different does it sound when it’s open to the sanctuary?
When it’s open to the rest of the sanctuary. The fun thing is that space out there is still largely&emdashuntil you get to the very back of it&emdasheven in the coverage pattern of the AX396. So what we did is we tied in a lot of those distributed speakers in a very low level way as such that your ear is not really drawn to those but it feels like they’re a good reinforcement of what you’re hearing from the main speaker cluster. [Timestamp: 9:24]

And where are you running the amplifiers from on these? Have you got them in a rack near the FOH or are they hidden somewhere in a closet?
Yeah, the amplifiers for all of the equipment are actually located in a room that is adjacent to the FOH location. It’s basically a room that’s dedicated to any rack gear and racks that needed to be associated with the AV system. [Timestamp: 9:44]

What kind of control do you have over the amplifiers? Is it pretty much a front-panel set or do you have a remote control over those?
Yeah, we actually used a Lab.gruppen C-series amplifiers with a Nomad Link Ethernet interface so that we could do some varying levels of control. There is front-panel control. So that has been tempered a little bit so that most of those things are pretty much non-adjustable without the right software just so that we don’t lose settings and gain and the ever-important gain structure, etc. What we’ve done instead is used the Lab.grouppen software to manage the C-series amplifiers. So from anywhere in the facility, we’ve got a non-broadcasting wireless network that allows you to log in, make amplifier changes, monitor your input, gain, and make any changes to those amps that’s needed. [Timestamp: 10:35]

Oh that’s great! That would be a really handy thing because you could have a lot better monitoring situation where you can hear what you’re doing than to have to do a lot of running around. So you used the Yamaha M7CL48ES as the FOH?
Yeah, that’s correct.

And that generates the timing for the EtherSound system?
It does. Yeah, the M7CL is a pretty slick setup. It’s got a couple of card slots in it that allow you to drop in specialty cards for different network configuration. So this church has got an Aviom system for all of their personal monitoring as well as the EtherSound system. The particular M7CL48ES that we used actually has all of the EtherSound outputs and inputs built right into the console without having to eat up those card slots. Though, in a traditional configuration with a standard M7CL you would have to get the specialty EtherSound cards to drop into those card expansion slots. In this system, the M7CL48ES actually acts as the configuration point and the controller for the two 16x8 EtherSound stage boxes that are all the way across sanctuary space in the green room behind where the alter is located. [Timestamp: 11:50]

And you mentioned the Aviom for stage monitoring. Does the M7CL handle all of the signal routing to send to those?
Yeah, what we actually do is all of the routing for the Aviom the system that gets them distributed over their proprietary A-net protocol out of that card slot in the back of the console. All of that routing is done through the M7CL’s touchscreen so you can do all of the patching depending on where you want to come out from the channels on the console. We happen to be using direct outs from all of the channels that need to be patched into that Aviom system and that all happens in the Digital Realms. You’re not doing any patch cables or anything like that. And of course, if the church wants to change their patching and change the configuration of the Aviom system, it’s very, very simple. It’s as easy a couple of direct out patches right in the console. [Timestamp: 12:36]

Well it would have to be I would think with all of the different music acts and being able to quickly transition from one to the other especially for the stage monitoring so it sounds like you’ve got a set up that really takes the load off doing all that. Josh, it’s been great having you on the SVC podcast for part one on this and talking about the set up in the Hosanna Lutheran Church in Mankato, Minn. And in part two, we can get into the training of volunteers and the wireless mic system, and it’s antenna set up and get into the projection because I think you’ve got a really interesting arrangement on that but thanks for being here for part one.
