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
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.

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.

WIRING DIAGRAM
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.
