The Shure Model 527C is a dynamic hand-held communications microphone for use in a variety of mobile and fixed-station applications, including police, transportation, amateur radio and similar applications. The 527C offers extremely low sensitivity to hum pickup and low susceptibility to radio-frequency interference. A built-in solid state amplifier permits the use of up to 30 m (100 ft) of unshielded cable. The modular construction of the 527C allows the cartridge, switch, and cable to be replaced in a matter of minutes, if necessary. The 527C fits naturally and comfortably in the hand and is not adversely affected by heat or humidity. The ARMO-DUR case is immune to oil, grease, fumes, salt spray, sun, rust and corrosion, and is outstanding in its ability to withstand mechanical shocks and vibration.
