I get a lot of questions from other tech leaders. And I’m OK with that. I really do enjoy helping people and solving problems. But I’m only one person, and I’m a busy one at that. Sometimes, emails and twitter questions can pile up and go weeks without being answered. I generally get to them eventually, but I feel bad when it take so long.
In the interest of spreading the wealth (of knowledge), I’m going to share with you the secret to acquiring knowledge. Learning new things has been one of my keys for staying employed, and I think it’s one thing that makes me good at what I do. So here you go; some of the secrets I’ve employed to learning more about this crazy trade.
Read the Manual
Yes, I know. Most of us pride ourselves on being able to take any new piece of gear out of the box and start using it without reading the manual. Well-designed equipment will even make that possible—at least to some extent. But when you start getting into the technical details of how to do something, often the fastest way to figure it out is read the manual.
I can’t tell you how many questions I’ve answered from people by simple downloading the manual for the product they’re having trouble with and reading it. Sometimes, I even cut and paste the relevant section in my answer.
Often, you will even discover cool features of a product that you didn’t know existed by reading the manual. I don’t even know how many times I’ve thought to myself, “I wish this box would do …” only to find it does because I read the manual.
I will acknowledge that many manuals are not worth the paper they’re not printed on (everything is a PDF now, right?) I’ve seen a manual for a mixer say, “The PFL button engages PFL mode,” and nothing more about it. Well, now that’s super-helpful isn’t it. I sort of figured pushing a button labeled PFL would do something related to PFL. And if you’re familiar with what PFL is, you probably don’t need that less than helpful sentence. But if you don’t know what PFL is, you need to go searching.
Use Online Help
More and more software is coming with built-in help that is actually useful. Just the other day, we were trying to figure out how to run a particular report in our new system-design software. We knew what we wanted was possible, but it wasn’t immediately obvious. So I hit the big ? button. It took me to online help section that eventually led me to the solution.
More and more, companies are using YouTube for really helpful instruction videos. I was trying to learn some new to me lighting software a while back, and discovered a whole slew of videos from the creator of the software. My learning curve shortened dramatically.
Again, I’ve done this for others. Many times, when I get a question about software, I’ll either launch my copy or download a demo and look for help. It’s amazing how many times the answer is right there. But sometimes the answer is there, but it doesn’t work. I was trying to convince a Blackmagic routing switcher to work the other day and while the manual told me what to do, I wasn’t getting the result I wanted. In that case, it’s time to pull out the big guns.
Use the Google
Google is probably the single greatest technical resource for a technical director today. You really should learn how to use it. Seriously. I’ve had questions come in and I’ve literally typed the question into Google and sent out a response based on my findings.
See, here’s the thing. Chances are, someone else has already needed to do what you’re trying to do. And they’ve probably already written something about it online. And Google knows where it is. Now, you could email me and ask, or you could just go to Google. Google is faster, by the way.
Google has become really good at taking in natural language questions and giving you good results. I was going to give you an example, but I do it so regularly that it’s become like breathing; I don’t even think about it. Just try it.
Someone asked me once if I had any online resources for training volunteers. You know what I did? I used the Google (and reminded them about this cool site called ChurchTechArts). When someone asks if I’ve heard about an obscure product, I use the Google. Do I remember where an article by someone is on a particular topic? Use the Google.

By now it should not be news to anyone that we put in a Bose RoomMatch PA in Coast Hills. I have taken no small amount of flack for that decision, but I stand by it, especially now that we really have it dialed in. As I’ve said before, there are other PA’s that we could have used, but none fit the budget and provided the directivity control RoomMatch does. And in that room, we really need control.
Asymmetric and Symmetric Boxes
As far as I know, we are one of the first installations to use both types of boxes in the arrays. Now, I should point out that RoomMatch may look like a line array, but it’s not. It’s billed as a Progressive Directivity Array. That means each box covers a specific part of the seating area. There is some combining at lower frequencies, but for the most part, the boxes don’t interoperate much.
Because of that, we were able to mix and match boxes for a very specific design. I wanted to provide some sense of stereo imaging across a wide chunk of seating in the middle, and keep as much sound off the walls as possible. To meet those goals, we used boxes that were narrow on the outside and wider in the middle at the top of the array. The arrays are mirror imaged and the coverage is indeed pretty tight.
Keep The Colors Straight
Apparently, when I wired up the arrays, it was dark and I was tired. I inadvertently wired a few NL4s wrong and we had some phase issues initially. But once we got that sorted out and began the tuning process, it was all fun.
A couple of guys from Bose came down and started taking measurements throughout the coverage area. They averaged those together and we came up with a room curve. Interestingly, the curve they came up with was shockingly similar to the one I put in using a LAMA transfer function with the measurement mic at FOH.
We ended up with about 4 filters in the system, and two of them are there to tame room anomalies. Otherwise, the system sounds really good out of the box. We did a little gain shading in the amps to dial out some summing that was happening with the LF elements in the arrays, and to compensate for the air loss at the HF end. But otherwise, the system is pretty flat.
Stereo Imaging for Days
I really wanted to have an LR system, but didn’t expect to get great stereo imaging. I was surprised to be wrong on this point. Throughout almost the entire center four sections and much of the back outside sections, there is an excellent sense of stereo. We played a bunch of tracks through the system and each time we kept looking at each other saying, “Wow, the stereo field is amazing!” It’s some of the best I’ve heard in a live PA.
But vocals image right in the center where they should and speaking sounds fantastically present. So I’m very pleased with that. Time will tell if they really utilize the stereo image as well is can be, but it’s nice to have it available.
The system also has four dual-18” subs in a cardioid pattern flown over the center of the proscenium. They are in a 2x2 arrangement and once we got the timing right, it’s pretty remarkable how little low end there is on stage. But throughout the whole seating area, there is plenty. We ended up dialing those back a little bit because Coast Hills has never been thumping the bass. There’s headroom there, however, should the new style of worship desire more bass.
Because the main boxes go down so low, the subs are really only working at the very low end, just like they are supposed to. Off hand, I don’t recall where they are working, but I believe it’s from about 30-90 Hz.
Good Lobby Sound
For the last 5 years I’ve been frustrated by the sound in our lobby. It was terrible, really. We had a bunch of ceiling speakers mounted in the walls. Under the best of conditions these won’t sound good, and these were not good conditions.
I spent a little more money in the lobby than I ordinarily would have, but I’m glad I did. We hung four RU8 Utility Speakers from Bose up in the corner where the wall meets the ceiling. The RU8 is a dual 8” plus a horn configuration, and it’s driven by a PowerMatch 8250. The 8250 puts out 250 watts into 8 channels, so each speaker is powered individually. I went with 8 channels because someday, they want to blow the front of the building out and put speakers out front. So they have 4 channels to expand into.
I didn’t have time to do any tuning of the lobby speakers, but I thought they sounded acceptable out of the box. At some point, I want to go in and play with the Smaart rig and tweak them a little bit, but for starters, it works. My choice of Bose speakers for the lobby was based on the idea that I wanted them voice matched to the mains. As you walk in from outside into the lobby, then into the sanctuary, it just keeps getting louder, but it sounds the same. I think we hit that goal.
Overall, I’m very pleased with the system. It has enough headroom to get really loud if they want, but it sounds clear at lower volumes. It’s very present without being harsh and has a nice, warm low end that doesn’t mask the midrange. And the lobby sounds good. That’s a win in my book.
Yesdterday after lunch, I notced a slight swelling on the side of my face near the top of my jaw. By the time I went home, it had become worse. But, I figured I could tough it out and do the show. During dinner, it swelled even more and was becoming quite painful. I decided to go to urgent care.
Long story short, I have an infection of a salivary gland. Its not terribly serious, but it did keep us from recordeing the show last night. Hopefully, we can get back on track for next week and from there on out. We have many great guests and shows planned, so stay tuned!
