Model 596LB User Guide
DYNAMIC HAND-HELD COMMUNICATIONS MICROPHONE
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.

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.

• Economical—the perfect choice for modest paging instal-
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.
