Advice From An Old Guy: Learn Your System


Once you clean up, learn your craft and show up on time (that is, early), it’s time to learn your system. Few of us have the luxury of walking into a new church job and getting to completely revamp the entire AVL system. Most of us will walk into whatever system is there and have to get to work. That means you’re going to have to spend some time getting to know how your system is put together.

Signal Flow
Depending on how competent the designer and installer of your system was, it may be easy or hard to figure out the signal flow of your system. Also, it’s possible the person before you didn’t know how anything was supposed to work, so they jacked it all up. That may mean you need to bring someone in for a day or two of help troubleshooting and mapping out the system. Or, you can do it yourself. Either way, you need to know how your system works.

Why? Because if you don’t, what will you do when something breaks? I had a rude awakening to this in my last church. About 3 months in, we came in on a Sunday to find the DSP that drove the house right hang was dead. I very quickly had to troubleshoot and then re-wire the system during rehearsal. It would have been a lot faster had I known how it was all put together. As it was, I wasted a lot of time figuring out which outputs of the DSP did what.

In that same church, the TD that followed me ran mic lines through the seats from FOH to the stage for something or another. When I pointed out that not only had I installed a half-dozen tie lines for that very purpose, but there were also three empty 2” conduits running that path, everyone was dumbfounded.

Sometimes we’ll go in to a church to revamp one system and while I’m there I’ll get questions about other systems. When I start inquiring how things are put together or how they are using a particular piece of gear, I’ll get looks like I’m from outer space. You may not have to be intimately familiar with each and every piece of gear, but it’s a really swell idea to know why it’s there and what it does.

It’s also really hard to troubleshoot when you don’t know what you’re working with. It’s important to note that I’m not chiding you for not knowing what all your gear does on day one. But I can tell you that I’ve looked like a genius on more than one occasion because I can use the Google. Plug the model number into the handy Google search bar and you’ll learn a lot. You might even be able to download a manual! Once you know what this piece of gear does, you’ll know when it’s not working. Or maybe that it’s not properly deployed. Or maybe it has capabilities that you didn’t know about and you can do more without ordering new gear. That also makes you look really smart.

Knowing your gear also makes it easier for your integrator to help you expand the system. I’ve shown up to more than one site and said, “Gosh, I wish I had known you had _______.” Sometimes that means things are easier. Sometimes, not so much.

Also note that I’m not demanding you know every single make and model by heart. You just need to know roughly what you have and how it works. When I was re-building my video system, I knew every single piece of gear and how it all went together. But a year later, when we moved on to audio, I probably couldn’t have told you every model number of every piece of gear in the system. However, I knew the principles on which it was built. Also, it helps to have drawings.

Knowing your system is key to successfully running a technical department. Like all things worth doing, it takes a little time. But trust me, it’s time well spent.
