In this episode of Pro Acoustics Tech Talk, Nathan and Coltin go over how to program a Crown Audio CDi Series amplifier. If you're confused about how to set up your Crown CDi amp, this video is for you.

Hey everybody, thanks for joining us again for another edition of Pro Acoustics Tech Talk. I am Nathan and I’m Coltin, and we’ve got a little bit of tile bridge and rough-in pan talk coming your way. So, when you're doing 70-volt in-ceiling speakers in commercial applications, sometimes it requires some additional hardware to mount the speakers. Sometimes it’s sold with the speaker, sometimes it's not. Because as we all know, lots of times commercial audio takes place in places with drop tile ceilings like you have above. Right. If you ever wonder what a drop tile ceiling is, you never heard that term before. It's basically the two by two or two by four T-bar grids that you see like in the classrooms when we were growing up, in the library, a lot of convenience stores now have them, that kind of thing. It's that white tile with all the black and gray holes in it. So basically, that's a dropdown ceiling. You know, there's an actual ceiling way above that, but they drop it down and then they run air ducks and all that kinda good stuff through it.

Hey everybody, welcome to another edition of Pro Acoustics Tech Talk. I'm Nathan, I'm Coltin and we are here today to talk to you guys about all different kinds of speaker wire, which speaker wire is most appropriate for your application. We’ll hopefully take some of the guesswork out of it and explain a little bit more about wire.

Do you ever wonder why your speakers keep blowing?

This can be more than a minor annoyance: blown speakers can cost you time, money, and precious sound quality. It’s not always a cut-and-dry case for determining if a speaker is blown or not, but you can follow a few of these tips to diagnose a speaker that’s gone awry.

Howls, squeaks, even roars – Those uncomfortable noises that make you cringe and cover your ears. Audio feedback can be a real pest, and ruin great musical performances and speeches. But why does it happen? And how can you prevent it?
