Product Description From Shure:
The 527A microphone is an extremely reliable, high-impedance, dynamic, hand-held microphones with an extended low- and high-frequency response particularly suited to ham radio use, mobile FM transmission, and top-quality paging systems. The microphones have a clear, crisp, and natural voice response. They features professional design, small size, light weight, and modular construction.
The 527B is wired for balanced-line operation and is recommended for use where long cable lengths are required, or areas where strong noise fields may exist. The 527B microphone can be fed directly into a standard low-impedance amplifier, or a Shure A95 Series Line Matching Transformer can be used for coupling the 527B to the input of a high-impedance amplifier. A two-conductor shielded cable can be used for extending only the microphone circuit. If both the microphone circuit and the remote circuit are to be extended, a four-conductor cable, having two shielded conductors for the microphone, should be used.
The Shure 527C is a dynamic hand-held communications microphone designed 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 these microphones allow the cartridge, switch, and cable to be replaced in a matter of minutes, if necessary.
They fit naturally and comfortably in the hand and are 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. The "Million Cycle" leaf-type switch is double-pole, single-throw, designed to withstand severe operating conditions and constant usage.
