MODELS 588SA, 588SB, AND 588SBE UNISPHERE
UNIDIRECTIONAL DYNAMIC MICROPHONES
B
General:
dynamic microphones with a very effective filter that provides excellent protection
from wind and "pop"
reproduction of music and voice, and are ideal for use with good quality sound
systems and tape recorders.
auditoriums, schools, churches, indoors or outdoors, and any place where omnidirectional microphones may not operate properly because of feedback problems.
These microphones will, in almost every instance, eliminate the annoying loudspeaker
"squeal" caused by feedback and can be used closer to loudspeakers than usual,
without feedback. This suppression of feedback, combined with their smooth sound,
makes these microphones ideal for use with orchestras, small combos, and vocalists.
The microphones feature
The Model 588SA, 588SB, and 588SBE Microphones are unidirectional
(explosive breath sounds). They feature a natural, life-like
These microphones are particulariy suitable for use in theatres, night clubs,
:
A
built-in wire-mesh screen with a special filter that provides protection from
wind "pop" (explosive breath sounds). This filter also enables singers and
speakers to perform close to the microphone.
A true cardioid pattern: symmetrical about axis and uniform at all frequencies.
This means that voice and music tonal quality remain the same, even if the
artist or speaker moues about while performing or speaking-and that feedback
and
boominess are eliminated or effectively suppressed.
Cartridge shock mounted for quiet operation.
A
built-in "ON-OFF" switch with provision for locking switch in its "ON"
position.
Versatility-for use in the hand or on a stand--indoors or outdoors.
An
adjustable swivel adapter that enables you to aim the microphone where you
want it. Swivel, also, allows for quick removal for use as a hand microphone.
The Model 588SA is high impedance and may be used with any high gain
amplifier with an input of 100,000 ohms or more.
The Model
588SB and 588SBE are low impedance and designed for connection
to a 25 to 200 ohm line or input. This is recommended where long cable lengths
are required or where there are conditions of severe hum disturbance.
588SB or 588SBE with a high impedance amplifier, use a Shure Model A95A
Model
To use the
or A95P Line Matching Transformer. The 588SB has 15 feet of cable, the 588SBE
has 30 feet.
Important:
superior performance in microphones
Shure Microphone Cables are selected after exhaustive tests to insure
becausc of low capacities, superior shielding
properties and unusually long life under severe use.
Cables with plastic insulation should not be subjected to excessive soldering-iron
heat. Carefully clean and tin the conductors and the connections to which the conductors are to be soldered. The soldering operation can then be done with a
minimum
of heat, thereby avoiding any possibility of damage to the cable.
Guarantee:
defects for a period of one year frcm date of shipment from factory, provided
Each microphone is guaranteed to be free from electrical and mechanical
all
instructions are complied with fully. In case of damage, return the microphone to the
factory for repairs. Our guarantee is voided if the microphone is subjected to accident
or abuse.
