The FCC's re-allocation of the 700 MHz band has been 10 years in the making, and now that the day of reckoning is upon us, wireless microphone manufacturers are moving forward with products and features they've had in the works to ease the transition. "[The FCC] created a safer zone further down the spectrum where no portable devices will operate, and that's where we believe most of the wireless microphone use will concentrate," says Mark Brunner, senior director of public and industry relations at Shure.
Audio-Technica began moving out of the FM band entirely about 10 years ago with its SpectraPulse Ultra Wideband technology. Sennheiser started moving its products into the 600 MHz band. According to Joe Ciaudelli, Sennheiser's consultant for professional products, we may ultimately see more mics operating per channel and the reintroduction of VHF equipment. "Even with all the congestion that might happen over the next few years, 18,000 frequencies is a lot to choose from," he says. "You're going to find a clear frequency."
