North Ridge Church's awesome sound system set up for only a few hundred dollars while putting out professional performances.

From Youtube description: This is a personal project I have been working on for a long time. I go over the use of TV splitters in wireless microphone systems. In the end you will see you can have an 8 way RF distribution for $1,700 LESS than what you would purchase a factory system for. Also there is no degradation of the signal using these splitters! Now, this is a long video, there is a lot that I cover in this video but all of it is important. I cover a lot of different things from the Frequency Spectrum of wireless mics, to antennas used in systems, and then using Television Coaxial Splitters for distributing to multiple wireless receivers.

What would be a practical application of this?

Nice work Drew. I’ve used even the cheap (”Realistic” brand) splitters with good results at VHF and UHF.

If you don’t have an SDR receiver, you’ll find one to be an incredibly useful tool to monitor and analyze your system. An Airspy R2 would be best, or an SDRPlay, but even a $8 rtl-sdr dongle will work perfectly for your needs, along with SDR# or SDR UNO or similar software that will let you see all of your mics, relative signal strength, etc. You could probably replace all of your receivers with multiple instances of SDR software and multiple VFOs but you already have the receivers. The advantage of an SDR-based approach would be simplified RF hardware and redundancy.

Good work, and a very nice video production.

Bookmarked.

Audiovisual booths in churches, sound systems set ups by musicians, and audio book recording studios. Some use by ham radio operators, too.

I’m not Drew. I simply thought it was useful, whether you’re a ham, musician or managing a sound system.

Oh, yea just wondered.

I’m a simpleton....

I used several countryman mikes with Shure digital PGXD wireless hooked to a Macke board.
