Performance Audio, based in Salt Lake City, Utah, is incorporating RF Venue Band-pass Filters into its wireless microphone system designs to improve reliability in increasingly crowded RF environments. The integrator had been seeing intermittent wireless dropouts that conventional frequency coordination alone could not fully solve, with expanded 5G wireless infrastructure in Utah contributing to the challenge.
The company designs and installs systems for theaters, schools, houses of worship and performance venues across the state. Systems could appear clean during commissioning, then begin dropping out once an auditorium filled with audience members carrying mobile devices, raising the RF noise floor. To address that condition, Performance Audio uses Band-pass Filters to reject unwanted RF energy before it reaches receiver distribution, specifies them on virtually every wireless installation, especially multi-channel microphone systems, and regularly pairs them with RF Venue Diversity Fin antennas.
The practical significance is a shift from relying only on frequency planning toward filtering interference before it enters the wireless receive chain. In venues where audience devices and nearby cellular transmissions are part of the operating environment, the added filters give integrators a direct way to support stable performance from professional wireless microphone systems already being installed.
