MONROVIA, CA — Jeff Dykhouse of WorshipMIX faced a mountain-sized challenge: to design and implement a 24-channel wireless RF system for Monrovia High School’s auditorium. The catch: Mt. Wilson, home to both the Mt. Wilson Observatory and an antenna farm for TV and radio signals, looms just above the school.
Slated for use with the school’s theatrical presentations and other events, the system was designed to exist, quite literally, in the eye of a very serious RF storm.
“There are more than 20 TV and radio stations broadcasting from the top of Mt. Wilson at ranges of up to 166,000 watts,” said Dykhouse, who chose Shure UHF-R wireless transmitters and receivers for his assignment. “Using Shure’s Wireless Workbench on my Mac, I turned on my receivers and let the software randomly assign frequencies for my 24 channels. More than two-thirds of the channel meters were pegged from interference, and I hadn’t even powered up a single transmitter of my own.” [read]
