MODELS 588SA AND 588SB
UNIDIRECTIONAL
GENERAL
The UNlSPHERE@ B Models 588SA and 588SB are
unidirectional dynamic microphones with a very effective filter for excellent protection from breath popping
and wind noise. The microphones are available either as
high impedance
(588SA) or low impedance (58888); they
provide natural, lifelike reproduction of vocal and instrumental music; they are ideal for sound reinforcement and tape recording.
These microphones are particularly suitable when
unidirectional sound pickup is required because of
feedback problems. Because they are unidirectional
and pick up sound from the front while suppressing
sound from the rear, the 588 Series can be used closer
than usual to loudspeakers without the annoying
squeal caused by feedback. They also permit higher
amplifier gain before feedback. They are very appropriate in locations such as theaters, night clubs,
auditoriums, schools and churches; indoors or outdoors.

To change the phase of a low-impedance microphone
cable, either use a Shure
A15PRS Phase Reverser or interchange the wires connected to pins 2 and 3 of the
connector. To change the phase of a microphone, the
microphone cartridge leads must be interchanged (see
Figure 4). This should be performed by your dealer, the
Shure Factory Service Department, or other qualified
service personnel.

PHASING
To test two microphones andlor their cables for proper phasing, connect them to an amplifier and talk or
sing into them while holding them three or four inches
apart. The sound from the speakers should be the same
when talking into either microphone or directly between
them if they are in phase with each other. If the sound
drops drastically, or if a dead spot is found when talking
between the two microphones, either the microphones
or their cables (low impedance only) are out of phase.
All cables and microphones should be tested in this
manner to insure that they are in phase with each other.
