NOISE-CANCELING HANDHELD DYNAMIC MICROPHONE

GENERAL

The Shure Model 577B SONOBAR® Microphone is a handheld dynamic

microphone designed for communications and paging applications that

require highly intelligible, low noise output. It can be used in all types of

mobile communications, from amateur radio to helicopter news and traffic

reports. It is also suitable for public address and paging systems in noisy

areas such as factories, airport terminals, and restaurants.

The 577B represents a significant improvement over most microphones

with anti-noise features. Shaped frequency response, directionality,

and distant sound discrimination contribute to total noise reduction. The

microphone operates on the pressure-gradient principle and has two sound

entry ports spaced a small distance apart.

The modular design of the 577B greatly facilitates field servicing. The

cartridge, switch, and cable can be replaced in a matter of minutes, if

necessary.

The 577B is built to withstand mechanical shocks, vibration, high

temperatures, and humidity. The exclusive ARMO-DUR

® case is impervious

to oil, grease, fumes, salt spray, sun, and corrosion. he “Million-Cycle”

press-to-talk switch ensures years of reliable service.

A mounting bracket is supplied to provide convenient hang-up when the

microphone is not in use.

Features

• Frequency response tailored for close-talk operation

• Extremely effective noise cancellation

• Dynamic microphone cartridge

• Modular design

• “Million-cycle” leaf-type press-to-talk switch

• TRIPLE-FLEX® cable provides three to four times the flex life of

most coiled cords

• Rugged ARMO-DUR® case

• Built-in hang-up button and supplied mounting bracket

OPERATION

For optimum performance and maximum rejection of background noise,

place your upper lip against the lip guard, approximately 25 mm (1 in.)

from the grille. Hold down the push-to-talk button while talking normally.

INTERNAL CONNECTIONS

The 577B is a balanced-line, low-impedance dynamic microphone. It is

designed for direct connection to low-impedance microphone inputs and/

or installations where long cable lengths are needed. It includes a four-

conductor (two conductors shielded) coiled-cord cable and a double-pole,

single-throw, leaf-type switch. The WHITE and GREEN leads are the “hot”

audio conductors; the shield is connected to microphone circuit ground. The

RED and BLACK leads control the switch circuit. The microphone circuit

is open when the switch is open, but can be easily modified for normally

shorted operation. Refer to Figure 1.
