600 MHz spectrum, the company said in a filing in docket 12-268, not yet posted by the FCC. “Now, if the 600 MHz spectrum auction and TV band repacking proceed as planned, microphone users will lose most of their remaining spectrum,” Sennheiser said. A proposal to allow continued operations in the 600 MHz guard bands won’t make up for the loss, Sennheiser said. “The guard bands are likely to receive out-of-band emissions from neighboring operations and to have power limits inconsistent with some uses of wireless microphones,” the company said. “Moreover, a performer’s ear monitors require frequencies separated from those for the microphone, resulting in a need for two distinct bands in UHF.” Sennheiser asked the FCC to “revisit its policies so as to make adequate UHF spectrum available.” Several options are available, including reserving “naturally occurring” vacant channels and Channel 37 for wireless microphones, “or setting aside additional spectrum from that to be auctioned,” the company said. The FCC should also require auction winners to pay the cost to move mics to other frequencies, Sennheiser said: “The Commission has recognized elsewhere the inequity of leaving incumbents to bear their own costs of relocating to a different band for the sole benefit of auction winners.” The German company said wireless mics are vital to the U.S. economy. “Wireless microphones are ubiquitous in all aspects of the entertainment business, in news reporting, in sports, and in U.S. commercial, civic, and religious life,” Sennheiser said. “They are essential to the production of virtually all non-studio broadcast events, and to nearly all studio-produced programs as well.”
