Radio noise!! The sound guy’s (gal’s) worst enemy!
We had a church built about a year ago with a really nice sound system that was AMAZINGLY better than the old one. I was constantly fighting noise of some kind in the old church, so this new one made me almost giddy with excitement. I was like a kid in a candy store!
Then it happened. We had a lightning strike! NOOOO!!!!
Not everything was taken out, but just enough to limit our capabilities for a couple of weeks. We called in the professionals and they replaced everything that was apparently affected, but now we have a country-western radio station rearing it’s ugly head intermittently.
Now don’t get me wrong – I have nothing against country-western music. I enjoy all types of music in their proper place. It’s just that I’m kind of a control freak and don’t appreciate uninvited music stations during the church service!!
I think it may be coming in through the electrical service somehow, but the electricians that wired the new church are now out of business and the elders are hesitant about paying for someone to come in and troubleshoot the problem, so it looks like I’m going to have to get off my lazy butt and spend some time tearing into the church’s electrical systems to see if I can find a clue.
Sigh…. honeymoon’s over.
One positive note, though – I do enjoy a good challenge, and by golly, I’m not letting a radio ghost kick my butt!!
More later…
I FOUND IT!!
Somehow one of the aux outs from my sound board got plugged into a line in.
I’m going to blame one of the video guys because it was behind their computer ;>).
I can see how it happened, though. First, let me explain how I have the video computer set up:
There is a dual adapter plugged into the video computer speaker jack – one line goes to the sanctuary sound system and the other one is supposed to go to the local computer speakers.
There is also an output from the sanctuary sound board that goes to the computer for recording the audio portion of the church service.
At some point, the speakers got unplugged and the recording input line got plugged into the dual speaker output adapter.
After I corrected it, the sound system output increased a lot, and the radio noise went away. (Please don’t make me explain where the radio noise came from or went to because I can’t) It took a couple of weeks to reset all my gains, but now I’m back in my happy place!
The great thing about computer connections is that they were designed to be “idiot proof” for the most part. Very few things can be plugged into the wrong place without force, and if it is plugged into the wrong place, usually no damage is done. All you have to do is match up the shapes of the cable ends to the connector on the back of the computer.
Here’s a quick video that explains some of those connections:
There are only 2 exceptions that I can think of where you can get things turned around with negative (but not drastic) results, and that’s the sound card connections and the PS/2 ports.
The PS/2 ports are the 2 small round ones with several pins in them. Your mouse and keyboard plug into these. Typically they are color coded, but not always. There is usually a symbol next to them on the back of the case indicating which one goes where. If you get them switched, no harm done, they just won’t work right. Just turn the computer off, switch them, turn the computer back on, and they should work fine.
I might add that the connectors need to be turned the right way before pushing them in. Never force them in. If they don’t seem to go in relatively easily, inspect the pins to see if any are bent.
Here’s a diagram of the connections on the back of a Dell Dimension:

What is the difference between a dvd ram and a dvd discs?
DVD-RAM is different from DVD+RW and DVD-RW. It is a rewritable media, but more reliable. DVD-RAMs can be accessed just like a hard or floppy disk and usually without any special software. DVD-RWs and DVD+RWs, on the other hand, store data in one long spiral track and require special packet reading/writing software to read and write data discs.
