Professional wireless microphones (and their cousins, wireless intercoms and in-ear monitors) share operating spectrum with television channels. We note which TV channels are active in the area, and set the mics to operate in an unoccupied spot… the “white space.”
In February 2009, part of that white space will be off-limits to us. The FCC is re-assigning frequencies between 698 – 806 MHz (the 700 MHz band) for Public Safety and cellular telephone activity. All wireless mic use in this range must be discontinued.
The preferred frequencies for our wireless gear will be between 470 – 698 MHz. It’s good to have a place to call “home.”
The major manufacturers (Shure, Sennheiser, Sony, Audio-Technica, Telex, Lectrosonics, and others) have not made products in the 700MHz band for some time. But you should check your equipment, especially if it’s a few years old.
If you have gear affected by the new rules, call BSW for the latest in wireless mics and in-ear monitors. You know where to find us: www.bswusa.com
