The Model 588SDX is a ball-type, dual-impedance, car-
dioid (unidirectional) dynamic microphone that provides
excellent voice reproduction. Its spherical grille is a very
effective wind and pop filter which is especially good
when used for closeup vocal miking. This microphone
is highly suited for speech or music pickup in schools,
churches, and meeting rooms. Its unidirectional polar
pattern greatly reduces feedback problems, permitting
operation closer than usual to loudspeakers without the
annoying squeal or howl caused by feedback.
The microphone is equipped with a lockable ON/OFF
switch and an internal impedance selection socket located
on the XLR connector for switching between high and low
impedance. A slip-in swivel adapter is supplied for the
convenience of stand-mounted use.

General Rules for Use
Aim the microphone toward the desired sound source
•
(such as the talker, singer, or instrument) and away
from unwanted sources.
Place the microphone as close as practical to the
•
desired sound source.
Work close to the microphone for extra bass response.
•
Use only one microphone to pick up a single sound
•
source.
Use the fewest number of microphones as practical.
•
Keep the distance between microphones at least three
•
times the distance from each microphone to its source.
Place microphones as far as possible from reflective
•
surfaces.
Add a windscreen when using the microphone
•
outdoors.
Avoid excessive handling to minimize pickup of
•
mechanical noise and vibration.
Do not cover any part of the microphone grille with
•
your hand, as this will adversely affect microphone
performance.
