Church Sound 101: RF & Wireless

What you will learn...

This course covers the essentials of wireless microphone and in-ear monitoring systems, as well as key facets of radio frequency (RF), in order to obtain flawless performance every time. Don’t worry – wireless is not “magic” or “voodoo” and it’s not that complicated.

Find out the essentials for success in this straightforward course presented by wireless system veteran Karl Winkler.

Band Planning: The air around us is filled with radio waves operating in many different frequency bands. Some of the sources include broadcasters (TV and radio stations), public safety (police and fire departments), cell phones and many others. They can present interference problems for wireless systems, which also operate (transmit and receive signal) within specific radio frequency bands. Therefore, it’s vital to understand what’s happening with the frequency bands in any area/building where wireless systems are operating. This course will show you how to do just that.

Antenna Types & Placement: There are several types of antennas, so it’s important to understand each type and then make the best choice(s) for your situation. And even with the right antennas, it’s also important to understand a host of best practices that if followed go a long way in helping to ensure consistently solid wireless system performance. These topics are particularly vital because wireless systems operate at relatively low output power, so we need to do everything possible (especially optimum antenna placement) to make sure that transmitters and receivers are linked as optimally as possible.

Frequency Coordination: In addition to band planning, frequency coordination is absolutely essential to optimum wireless system operation and performance. It’s simply the process of calculating and choosing frequencies so that your transmitters and receivers will not be compromised by interference. There are several tools that can also be helpful in this process – find out what they are and how best to use them.

Checklist: A handy list of the necessary steps to success every time you employ wireless systems. Start off right and it all flows well from there.
