Omnidirectional Dynamic Base Station Microphone, Low Impedance, Desktop

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 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 "Million-Cycle" leaf-type switch is designed to withstand rigorous operating conditions and constant use.
