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 applica-
tions in budget-restricted paging and other installations. The
microphone is compatible with many popular paging ampli-
fier inputs. Its tailored frequency response provides clear, in-
telligible 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 ca-
ble 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 operation
• Frequency response from 200 to 5,000 Hz, tailored for voice
communications
• Economical-the perfect choice for modest paging installations
• Rugged and dependable under most operating conditions
• Silver-plated switch contacts for long-term low contact resis-
tance 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 equipment
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.
Refer to the following tables and to the wiring diagram below.
WIRING DIAGRAM
FIGURE 1
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.

OPERATION
The 596LB will operate satisfactorily under most conditions
of humidity, heat and cold. Dropping the microphone or
other severe mechanical shocks should be avoided.
