High-Performance as a System or In a System
A giant step forward in professional quality sound reinforcement
loudspeakers. The Model 701 is a highly efficient, lightweight, portable
two-way speaker system which provides high SPL sound reinforcement
of wide-frequency range program material for every location from large
auditoriums to the most intimate clubs.
Advanced computer design techniques have made it possible to
produce a wide-range efficient loudspeaker system in a startlingly small
encic Jre. The 701 is designed to operate with an amplifier capable of
delivering 150 watts continuous to an 8-ohm load. Delivers a walloping
100.5 dB sound pressure level (SPL) at 1.2m (4 feet) with one watt!
Exclusive Adjustable Dispersion Tailors the Sound to the Area
The PRO MASTER 701 is an ideal companion to the Model 700 PRO
MASTER console, or it can be used separately with other components, or
as part of "house" systems. You can easily modify it for biamplified
operation. And PRO MASTER 701 loudspeakers are super as musical
instrument speakers for synthesizers, other keyboards, and guitars.
Finallyl A loudspeaker that puts the sound where you want it ... with the
twist of a knob. Shure calls it Adjustable Dispersion-soundmen call it
indispensable I
Faced with a long narrow room? Set the high-frequency horn for a 60°
long-throw pattern. Wide room? Set it for 120° wide-angle coverage.
Nothing else like it, at any price.
w
Ultra-Transportable and Practically Abuse-Proof
Every extra ounce, every unnecessary cubic inch, has been computer
designed OUT of the PRO MASTER 701 loudspeaker. Going on the road?
No musclemen or dollies are required. Two 701 speakers (plus a console)
easily fit into virtually any subcompact car. That means you CAN take
them with you-easily!
The PRO MASTER loudspeaker enclosure is solid 15.9 mm (5fs in.)
plywood, vinyl covered, and the horn is structural foam ... so it's
lightweight and unaffected by high humidity (unlike heavy
particleboard). The PRO MASTER 701 has been torture-tested to
withstand the kind of bumps and abuse that go with repeated setups
and takedowns.

Models 707 and 708
In response to many requests by sound installers and entertainers, Shure has made
the high-perfo rmance, effic ient high-frequency horn and low-frequency sections of
the PRO MASTER"< 701 loudspeaker system available in modu lar form. Model 707
is the low-frequency module; Model 708 is the high-frequency module. These
mod ular units may be used to construct a custom speaker stack, to add hi gh- or
low-frequ ency emph asis to anothe r full-rang e system, or to create a custom stag e
monitor system .
Put Together YOUR Sound
Model 708
The physica l and electroacoust ic charac teristics of both these modu lar units make
them extraord inarily versatile
HIgh-Frequency Module
Us ed tog eth er, a 707 and 708 are electrically and acoust ically eq ui valent to a Shu re
Mod el 701 full -range speaker system: they provide lu ll -range reinforcement with no
external crossover needed, or they can be biamped with separate power amplifiers
and an electron ic c rossover.
Used separately, they can be stacked into many differen t conven ient
configurations. When intense low and middle frequencies are desired, as in discos,
a st acked 701 and 707 will provid e a substantial low-frequenc y emphasis
Whe n it is necessary to cut through with mo re high-frequen cy energy, a 701 and an
added 708 wil l do the job.
Performance Plus!
PRO MASTE R 707 and 708 loudspeakers are each designed to operate with an
am plifier capab le of deliveri ng up to 150 watts continuo us to an 8-ohm load .
They com bine a clean soun d with high SPL sound reinforcem en t to meet the
most demanding requ irements of modern musicians , in conventional and
unconventional setups.
They are bu ilt to the same standards of ruggedness as the PRO MASTER 701, and
to rt ure-tested to withstand the same kind of bumps and abuse that go wi th
repe ate d setups and ta kedowns on the road.
Model 707
The low-frequency module has a 381 mm (15-i n.) woofer in a front -ported bass
reflex cabinet with rubber feet on two surfaces, and a beveled back allowing the

Model 703 Stage Monitor
A high-quality, high-output stage monitor with unprecedented four-way
flexibility and applicability. Patterns the sound to zero in on you anywhere
on stage. Unique adjustable dispersion high-frequency focusing
wedges, combined with long- or short-throw speaker positions, enable
you to concentrate the sound energy on the part of the stage where it is
most needed.
We've got your act coveredl
Special removable wedges (circle below) make it possible to achieve
wide-angle 120° coverage for greater freedom of movement on stage, or
a tight 60° angle for a narrow "personalized" pattern and minimum sound
spillover from one monitor to the other. (The 60° angle also increases the
high-frequency response by approximately 5 dB.)
Set the speaker on its back at the foot of the performer for close-up use, or
place it upright when the performer is farther away. Whatever the
situation, the 703 puts the sound where it serves the performer!
Shaped Response Cuts Through
Incorporates the special Shure-developed performance-proven shaped
response for monitor speakers. Controlled bass rolloff and boosted
mid-range puts the sound energy where it belongs in monitor
applications. (Ends bass muddiness that degrades many monitor
speakers-vocals cut through cleanly, whatever the level of the
background sound.)
High Efflclencyl
As with all speakers in the PRO MASTER line, the 703 uses highly efficient
loudspeaker components to produce high sound pressure level, a hefty
97 dB SPL at 12m (4 ft.) with a one-watt input, and up to 117 dB SPL with
100 watts! The high-frequency driver and two 203 mm (8 in.) heavy-duty
speakers provide excellent sound reproduction from virtually any power
amp capable of delivering up to 100 watts to an 8-ohm load.

discos, churches, studio monitor systems, schools, etc. The SR112B is
designed to be weather-resistant, for use outdoors in semi-permanent
installations. SR112W has a woodgrain finish for permanent indoor
installation in applications where it is important that exterior appearance
of the unit fit with existing decor, such as in churches, meeting rooms, or
discos.

Handles a Lot of Power... Efficientlyl
The exceptional output power capability of the SR112B-SR116B speaker
systems is the result of combined high power handling and efficient
speaker design. They are designed to operate with amplifiers delivering
up to 100 watts continuous power into 8 ohms, such as the Shure Model
700 PRO MASTER'" Console, the Shure SR1 05 Power Amplifier or similar
high-power amplifiers.
For equivalent sound pressure level, the SR Series requires one-third the
power of other compact speakers that requi re equal izers for full-range
output I With one watt input, both speaker systems produce a sound
pressure level (SPL) of 95.5 dB at 1.2m (4 ft). That's 6 dB higher
efficiency than some other brands of moderate size speakers, noted
for thei r efficiency
Full-Range Response
The natural, lifelike sound quality is the result of two high power,
heavy-duty 203 mm (8-in.) bass speakers and a high-frequency driver

coupled to a 120 radial horn. Low-frequency performance is achieved
· "'rough front-ported bass reflex design of the enclosure. A four-position
Itch allows individual high-frequency level adjustments in 2 dB steps.
