If you don’t want to read the history of how and why we got to where we are today, know that we have a very small amount of air space to operate our wireless microphones, monitors, etc. We have to work around the sources causing radio interference outside and inside. Most people don’t know wireless systems compete for space with non-audio wireless equipment. In fact, wireless systems compete with things that aren’t audio-related at all. LED lighting, LED video walls, video displays and other non-audio components create interference.
Our customers benefit from our on-site service. We scan sites to know all of the interference, inside and out, BEFORE making recommendations for purchase. Some mail-order suppliers will reference online resources like this one from Shure. Frequency finders show how many simultaneous units can be used in each zip code. While these resources show what is possible in a perfect world, they do NOT show local users and the interference they may generate.
Every system we design and install has filters to reduce the interference caused without and within the four walls. Antennae are explicitly selected for the environment. The cables, length, and amplifiers are chosen to minimize noise and maximize reception. Antenna distributors and combiners ensure each receiver receives the strongest, cleanest signal from one central antenna.
We receive calls weekly from wireless users who have lost all functions of their illegal systems and don’t know why. They can’t understand why wireless can’t be turned on and left unchanged for decades without issue. Those days are over! Wireless is no longer a set-and-forget thing. It should not be considered reliable without active management. Active management requires learning to scan, choreograph frequently, and test systems to compensate for internal and external changes.
