DYNAMIC HAND-HELD COMMUNICATIONS MICROPHONE

GENERAL

The Shure Model 596LB is a compact, hand-held dynam-

ic, low-impedance communications microphone with a 200

to 5,000 Hz frequency response. Designed especially for

voice communications use, it is an economical unit for ap-

plications in budget-restricted paging and other installa-

tions. The microphone is compatible with many popular pag-

ing amplifier inputs. Its tailored frequency response provides

clear, intelligible operation. The ARMO-DUR

 case is small,

light and sturdy, and fits comfortably in the palm of the hand.

It has a long-life push-to-talk switch, and a durable coiled

cable for years of reliable performance. The 596LB has a

low-impedance output.

The 596LB is furnished with a sturdy mounting bracket for

permanent installation.

Features

Omnidirectional pickup pattern for optimum off-axis op-

eration

Frequency response from 200 to 5,000 Hz, tailored for

voice communications

Economical—the perfect choice for modest paging instal-

lations

Rugged and dependable under most operating conditions

Silver-plated switch contacts for long-term low contact re-

sistance and reliable performance

Long-life vinyl-jacketed coil-cord for years of trouble-free

operation

Output impedance matches most paging amplifier inputs

Virtually indestructible ARMO-DUR case

Sturdy, convenient mounting button for attaching to equip-

ment or nearby surface using supplied mounting bracket

MOUNTING

The 596LB is provided with a rear-case hang-up button for

use with a mounting bracket on or near associated equip-

ment. The bracket has mounting holes with clearance for

No. 6 or No. 8 screws (not supplied).

CONNECTIONS

The internal switch connections of the 596LB are shown in

Figure 1. The 596LB has a four-conductor, coiled-cord cable

(two conductors shielded) and a double-pole, double-throw,

push-button switch to control the microphone circuit and an

external relay or switching circuit. The RED and BLACK un-

shielded leads control the relay or switching circuit.

CLOSURE

The 596LB can be wired for balanced-line operation and is

recommended for use where long cable lengths are re-

quired, or conditions where severe hum pickup may exist.

The 596LB can be fed directly into a standard low-imped-

ance amplifier input, or a Shure A95 Series Line Matching

Transformer (at the equipment end of the cable) can be used

for coupling the 596LB to the input of a high-impedance am-

plifier. A two-conductor shielded cable can be used for ex-

tending only the microphone circuit. If both the microphone

and the remote circuit are to be extended, a four-conductor

with two shielded conductors should be used.

The microphone circuit of the 596LB is normally open

when the microphone switch button is not depressed.
