SPEAKER SYSTEM
OPERATION AND SERVICE INSTRUCTIONS
DESCRIPTION
The Shure Model 701 PRO MASTERTM Speaker System
-a
wide-range, high efficiency, lightweight, portable,
two-way speaker system-is
an ideal companion unit to
Shure's Model 700 PRO MASTER Power Console or
similar high-power amplifiers. The Model 701 provides
high SPL sound reinforcement of wide frequency range
program material in every location from the largest audi-
toriums to the most intimate clubs. The speaker system
consists of a 15-inch woofer in a front-ported bass-reflex
cabinet and a high-frequency horn and driver combina-
tion with an adjustment for either a 120" or 60" horizon-
tal dispersion angle. The newly designed high power,
high-frequency
driver,
manufactured
exclusively
by
Shure, has a high-flux-density gap (more than 16,000
gauss) and a fatigue-resistant, high-temperature-tolerant
diaphragm and coil assembly.
The 701 has a built-in passive high-frequency LC
crossover network. The speaker system can easily be
converted to biamplified operation. Below the 2,000 Hz
crossover frequency, the crossover network rolls off at
18 dB per octave, providing the proper acoustic match
and protecting the high-frequency driver. In addition, an
overload protection circuit safeguards the high-frequency
driver against damage from extremely high level signals.
The low-frequency woofer rolls off acoustically above
2600 Hz.
The 701 system has a frequency response of 50 to
15,000 Hz and an impedance of 8 ohms. The system is
designed to operate with amplifiers capable of delivering
up to 150 watts continuous to an &ohm load.
The 701 is constructed of 15.9 mm (% in.) wood and
covered in scuff-resistant black vinyl. The black fabric
grille is rugged, cleanable, and easily removable and re-
placeable. The corners of the cabinet are equipped with
steel protectors. The 701 weighs only 26.4 kilograms
(58 Ib) and can be easily carried by grasping the cabinet
at the top and sides of the horn. Proper lifting techniques
should be observed when handling any equipment of this
size and weight.
A heavy-duty, 15m (50 ft), 18-gauge, rubber-jacketed
connecting cable with phone plugs is supplied with the
speaker. A rugged vinyl slip-on protective cover with a
cable pocket is available as Model A701C.
