The Shure 527C microphone is an exact replica of the 527B, except for an internal transistor amplifier that strengthens output signal, and allows the use of up to 30 m (100 ft) of unshielded cable without signal degradation.
The reliable handheld dynamic microphone features an extended low-and high-frequency response particularly suited to ham radio use, mobile FM transmission, and top-quality paging systems. The microphone has a clear, crisp, and natural voice response. It features small size, lightweight, and modular construction.
The modular construction of the 527C permits ease of field serviceability. The design of the cartridge, switch, and cable makes them easily replaceable. The microphone is wired to prevent lead breakage or crimping.
The unit fits naturally and comfortably in the hand and is not affected by heat or humidity. The exclusive 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 vibrations. The "Million-Cycle" leaf-type switch is designed to withstand severe operating conditions and constant usage.
