“I would highly recommend that churches look to a reputable sound company for evaluation of their wireless needs.”Ĭhurches and other organizations who don’t move away from using the 600 MHz range will potentially face a fine that could reach into a six-figure range, according to Michael Thompson, president of Thompson Sound, Inc. “It is only a matter of time until more of the frequency spectrum will be sold off, so investment in new digital wireless mic systems seems to be the best answer at this point,” he added. “The problem is that the units will not stop working but will start having more and more interference.”Īlthough it means investing in new equipment, Gunn said he encourages churches not to continue in what will soon be an illegal system. “The auctioned frequencies in the 600 MHz range is probably the most used band,” said Gary Gunn, a wireless microphone expert at Vision2 Marketing in Nashville. Many, if not most, wireless microphones in churches use the 600 MHz band. government auctioned off most of the 600 MHz frequency band to private companies and now T-Mobile is in control of most of that band of frequencies.īy July 2020, and earlier in some areas, people must cease using this band or face financial penalities. Church sound teams, listen up - and you may need a different mic frequency to do so.
