Last time, I explained the test parameters, the setup and listed the batteries under test. Go back and read that post if you want to see the test conditions (yes, I had the battery meters set correctly to match the chemistry of the batteries). Today it’s time for the results show. Based on the traffic [...]

Mid-Week Tech; The Illustrated Guide
By popular demand (at least on Twitter), here’s an illustrated guide I created for running our Mid-Week Bible Studies. All that’s needed is a wireless mic or two, house lights and one other area light, and a CD record. However, our system is overly complex and not volunteer friendly (FOH is a PM5D-EX). So, rather [...]
New Danger for Wireless Mics in Churches
Kirk Longhoffer posted an informative article at Church Tech Matters about the future of wireless mics. You should already know about the relocation of the 700 MHz spectrum (if you don’t, click on the DTV & Wireless tab above). And you should already know about the upcoming TVBDs (TV Band Devices; formerly White Space Devices). [...]
Creating the Big Picture
Long-time readers of this blog know that I’m all about developing a well thought out game plan before starting any system upgrade. Perhaps it comes from my background in carpentry and construction–one would never (OK, at least one should never) undertake a new building or renovation project on without a well-developed plan. When trying to [...]
It’s Time For Another Webinar
Fresh off the heels of our last highly attended webinar (OK, it was last April and about 20 people joined in…), Dave Stagl, Jason Cole and I have decided it’s high time we did another one. Why? Mainly because we have a lot of fun doing them (and because a few people said they enjoyed [...]
Saving Audio-for-Video Levels
Let’s say you are assigned to shoot an interview video. You set up the location, position the lights, mount the camera on the tripod and test the mic. Everything is in order. Your interview subject arrives, sits in place and as the tape rolls, the interview begins. The shoot is a success–or at least you [...]
Keeping up with the FCC
This is coming a few weeks after the fact, and some of you may already be aware of this but it’s important to note that on November 18, 2008, the FCC finally released it’s official ruling on what had been called White Space Devices (WSDs). They are now called TVBDs (TV Band Devices). While there’s [...]
Update on FCC Ruling
It’s been a week since the FCC voted on the issue of White Spaces. The cynic in me believes that they chose Nov. 4 as their day to vote figuring the rest of the country would be earnestly following the other election, and they could escape any real critique. That may be, but the techies [...]
Troubleshooting AV Systems
I thought I would jot down a few notes about what I’ve learned in 20+ years of troubleshooting AV systems. For this article anyway, I’ll focus on signal path issues, as those tend to be the most common in churches. While I’ll use examples from the world of sound, the principles are equally applicable to video and data signal lines.
