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 b i n c h 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 B. 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 of 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 B) 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.
