FIGURE A. SR102 SPEAKER COLUMN

DESCRIPTION

The Shure Model SR102 and SR103 Speaker Col-

umns are speaker systems designed for use with

Shure Model

SR105 or similar high-power amplifiers

in sound reinforcement applications. When properly

installed and connected, the

SR102 and SR103 Col-

umns will provide outstanding performance. Their wide

frequency range, distortion-free reproduction and high

sound penetration power make them a valuable asset

to any sound reinforcement system. The Columns may

be used with either direct

(4-

lo 16-ohm) or constant-

voltage 25- or 70-volt amplifier outputs.

Quality sound reproduction is achieved through the

use of two 10-inch and four

binch heavy-duty speak-

ers, plus two high-frequency speakers which combine

the functions of dome radiators and acoustic horn

radiators. The tuned-rear-port enclosure design con-

tributes to the highly directional pattern, which is

critical in achieving maximum audience penetration

and feedback reduction. The inductive-capacitive di-

viding networks maintain frequency-selective distribu-

tion of signals to the proper speakers.

The

SR102 Column

is a portable unit (see Figure

FIGURE

SR103 SPEAKER COLUMN

A), and is primarily designed for temporary installation

either indoors or in a protected outdoor environment,

such as under an open pavilion. The Column may be

operated vertically on its own feet, or in a tilted posi-

tion using an optional easel-type tubular stand (Shure

A3S-T). The

SR102 Column is supplied with a 15m

(50-foot), 18-gauge, rubber-jacketed connecting cable

with locking phone plugs. The lower rear section

the

Column contains a cable storage compartment. The

SR102 Column is covered with a tough vinyl surface,

front and rear metal grilles are finished in durable

black enamel, and trim is anodized to minimize visible

wear. A retractile handle and balanced design con-

tribute to ease of transporting.

The

SR103 Column

(see Figure

is a weather-

resistant unit, and is primarily designed for permanent

installation either indoors or in a protected outdoor

environment such as under the roof of an open pavil-

ion. Electrical components, hardware and enclosure

surfaces have been designed to maximize resistance

to adverse weather, with drain holes provided to min-

imize moisture accumulation. Adhesives used in the

SR103 Column are moisture-resistant and trim and

fastening hardware have a high corrosion resistance.
