SHURE 527B Dynamic Communications Microphone
GENERAL
The 527B microphone is an extremely reliable handheld dynamic microphone with
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 527B
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.

APPLICATIONS
The 527B microphone is highly recommended for all types of mobile
communications, ham radios, industrial and commercial paging systems, and
outdoor public address systems. The 527B is a low-impedance microphone and is
recommended where long cable lengths are required.
INSTALLATION
A quick-release mounting bracket for permanent installation is supplied with each microphone. The bracket has mounting holes with clearance for No. 6 or No. 8 screws (see Figure 4).
CONNECTIONS
The internal switch connections of the 527B are shown in Figure 1. The 527B has a four-conductor, coiled cord cable and a double-pole, single-throw, leaf- type switch to control the microphone circuit and an external relay or switching circuit. The WHITE and GREEN leads are the audio conductors for balanced-line connection to the microphone circuit; the shield is connected to the microphone circuit ground (see Table 1).
