Are your wireless mics legal?
Wireless mics operate on the same frequency spectrum as the wireless broadband spectrum. This includes TV and radio as well as cell phone communication. They aren’t supposed to overlap at all- we get a slice, they get a slice and so on. However, the FCC has technical control over the distribution of those frequencies and occasionally must reorganize them to accommodate the overall need. Unfortunately, this summer they completed a deal eliminating a slice of frequencies we used in wireless equipment. This means available frequencies for our devices are changing. This is a process under the direction of the federal government and therefore we have no say in what happens.
As of July 2020, the spectrum of 617-652 MHz and 663-698 MHz are no longer legal to operate in the US. Using those devices now poses a threat to the broadband transmissions and you’re likely going to end up with interference on your channels anyhow. Worst case you could face penalties from the FCC.
The process began about 2 years ago and hasn’t been fun for anyone. Production companies like ourselves own dozens of units and many of them fall into this range. As such we’ve been transitioning out of using them and replacing them with units in available frequency ranges. However, we recognize that many schools, houses of worship and smaller institutions may only have one wireless mic and will be surprised when it stops working.
If you’re concerned or want to find out more about your system you can contact the manufacturer or give us a call. We stay up to date on all the changes and we’ll be happy to help you navigate these confusing new regulations.
