OMNIDIRECTIONAL DYNAMIC MICROPHONES
GENERAL
The Model 533 Series Microphones are dynamic
omnidirectional microphones with a spherical front.
The units provide wide range reproduction of music
and voice, making them ideal for general purpose use
in public-address, theater-stage sound systems, and
tape recording applications. Rock and other groups
will find these microphones particularly desirable. They
are also recommended for interview type use where
"hand-ability" of the microphone is important.
Microphone Features:
Uniform frequency response from 40 to 11,000 Hz
Built-in wind, breath, and pop filter
m Small size and light weight
A built-in On-Off switch
Versatility - for use on a floor or desk stand -
indoors or outdoors
Dependability under all operating conditions
The Model 533 Microphones are supplied with an
adjustable swivel adapter which permits the micro-
phone to be tilted through 90" from vertical to hori-
zontal. This swivel also allows for "quick-disengage"
for use as a hand microphone.
Model 533SA is high impedance for connection to
high-impedance microphone inputs.
Model 53388 is low impedance for connection to
microphone inputs rated at 19 to 300 ohms. The low-
impedance microphone is recommended where long
cable lengths are required or under conditions of
severe hum disturbance. The permissible cable length
is practically unlimited, since neither response nor
level is appreciably affected. Shure Model A95 Series
Line Matching Transformers are available for use in
those cases where a low-impedance microphone line
is desirable but the associated amplifier has a high-
impedance input. These transformers provide a proper
impedance match between a 19 to 300 ohm micro-
phone line and a high-impedance input and are
available with various input and output connectors.

PHASING
To test two microphones and/or 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 di-
rectly 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,
they are out of phase. All cables and microphones
should be tested in this manner to insure that they are
in phase with each other.
To change the phase of a low-impedance micro-
phone cable, either use a Shure A15PR Phase Reverser
or interchange the BLACK and WHITE cable leads at
the equipment end of the cable. To change the phase
of a microphone, the microphone cartridge leads must
be interchanged (see Figure 3). This should be per-
formed by your dealer, the Shure Factory Service De-
partment, or other qualified service personnel.
