MODEL 588SDX
UNIDIRECTIONAL DYNAMIC MICROPHONE
The Model 588SDX is a ball-type, dual-impedance, cardioid
(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 prob-
lems, 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.
Features
•
Controlled low-frequency response combined with a
smooth high-frequency rise for clear and intelligible voice
pickup
•
Symmetrical cardioid pickup pattern minimizes feedback
•
Spherical grille provides effective filtering out of breath
noise and popping when used for closeup vocals, and of
wind noise when used outdoors
•
Neodymium magnet for high signal-to-noise ratio
•
Shock-mounted cartridge for quiet operation and low
stand/ handling noise
•
Lockable ON/OFF switch

BASIC RULES FOR MICROPHONE USE
1. Aim a directional microphone toward the desired sound
source (for instance, a talker or singer) and away from
undesired sources (such as loudspeakers).
2. Locate the microphone as close as practical to the desired
sound source for the best gain before feedback.
3. When extra bass response is desirable, work close to the
microphone. See Figure 1 for the close-up increase in low
frequency output called "proximity effect".
4. Do not pick up the same sound source with more than one
microphone. Keep the distance between multiple micro-
phones at least three times the distance from each source
to its intended microphone.

5. Use the fewest microphones practical for the particular
application.
6. Locate microphones as far as possible from acoustically
reflective (hard or smooth) surfaces.
7. Add an external windscreen when additional pop protec-
tion is needed: outdoors in windy conditions or for closeup
vocal use.
8. Avoid excessively handling the microphone to minimize
mechanical noise pickup.
9. To preserve directional characteristics, do not obstruct
the grille with your hand.
