Shure 596LB User Manual

DYNAMIC HAND-HELD COMMUNICATIONS MICROPHONE

GENERAL

The Shure Model 596LB is a compact, hand-held dynam­ic, 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 ap­plications in budget-restricted paging and other installa­tions. The microphone is compatible with many popular pag­ing 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 equip­ment. 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 un­shielded leads control the relay or switching circuit.

Refer to the following tables and to the wiring diagram below.

The 596LB can be wired for balanced-line operation and is
recommended for use where long cable lengths are re­quired, or conditions where severe hum pickup may exist.
The 596LB can be fed directly into a standard low-imped­ance 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 am­plifier. A two-conductor shielded cable can be used for ex­tending 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.
