Designed for intelligible speech.
The Shure 550L is an omnidirectional dynamic base station microphone with a frequency response specially tailored for voice intelligibility. It is equally useful for radio communications, paging and dispatching systems, and its low-impedance connection makes it adaptable to most PA amplifiers. The low-impedance design also makes it useful for long runs of cable, or under severe hum disturbance conditions.
The 550L desktop microphone is not affected by heat or humidity. Its exclusive ARMO-DUR case is immune to oil, grease, fumes, salt spray, sun, rust, and corrosion -- and is outstanding in its ability to resist mechanical shocks and vibration. The microphone's "Million-Cycle" leaf-type switch is designed to withstand rigorous operating conditions and constant use.
