OMNIDIRECTIONAL DYNAMIC MICROPHONE
WITH BUILT-IN VOLUME CONTROL
GENERAL
The Model 533SAV Microphone is a dynamic omni-
directional unit with a spherical pop-filter. The micro-
phone provides wide range reproduction of music and
voice suitable for general purpose use in public-
address, theater-stage sound systems, and tape
recording applications. Vocal and instrumental groups
will find this microphone highly desirable because its
"pop-proof" design makes it ideal for closeup opera-
tion and its Volume Control feature makes it possible
to adjust the amplifier output from the microphone
position. The 533SAV is also recommended for inter-
view type use where "hand-ability of the microphone
is important.
Microphone Features:
rn
Uniform frequency response from 40 to 11,000 Hz
m
Built-in wind, breath, and pop filter
m
Small size and light weight
rn Built-in Volume Control, can also be used as an
On-Off switch
Versatility-for use in the hand or on a floor or
desk stand-indoors or outdoors
rn
Dependability under all operating conditions
The Model 533SAV is supplied with an adjustable
slip-in swivel adapter which permits the microphone to
be tilted through 90" from vertical to horizontal. The
adapter also allows for "quick-disengage" to use the
microphone as a hand-held unit.
The Model 533SAV is high impedance for connec-
tion to a high-impedance microphone input. Shure
Model A95 Series Line Matching Transformers are
available for use in cases where cable lengths over
7.6 meters (25 feet) are required or where the micro-
phone is to be connected to a low-impedance input.
These transformers provide a proper impedance match
between a high-impedance microphone line and a
low-impedance input and are supplied with various
input and output connectors.
The built-in Volume Control on the microphone per-
mits the user to change the loudness of the PA system
at the microphone location.
With the Control on the microphone partially turned
down (turn the knob counterclockwise so that the dot
on the knob is at the 9 o'clock position), the basic
overall loudness of the
PA system can be adjusted by
the main volume control at the amplifier location-
then the user can adjust the volume up or down at the
microphone position. Maximum volume occurs when
the dot on the knob is adjacent to the dot on the mi-
crophone (12 o'clock position). In many instances,
minimum setting of the Volume Control will reduce
volume sufficiently so that the Volume Control can be
used as an On-Off switch.

ARCHITECTS' SPECIFICATIONS
The microphone shall be the Shure Model 533SAV
or equivalent. The microphone shall be a moving coil
(dynamic) type with a frequency response of 40 to
11,000
Hz. The unit shall have an omnidirectional polar
characteristic. The microphone shall be high imped-
ance for connection to high-impedance microphone
inputs.
The microphone output shall be -59 dB where
0 dB = 1 volt per microbar.
The microphone shall be equipped with a built-in
Volume Control. The microphone shall be provided
with a swivel adapter, adjustable through 90" from
vertical to horizontal, and suitable for mounting on a
stand having a %"-27 thread. The microphone shall
also be provided with a detachable 4.6m (15 ft) one-
conductor shielded cable with an Amphenol MCI F type
connector at the microphone end. The overall dimen-
sions of the microphone shall be 168 mm (6-19132 in.)
in length and 52.4 mm (2-1116 in.) in diameter.
IMPORTANT
Shure Microphone Cables are selected after exhaus-
tive tests to insure superior performance in micro-
phones because of low capacitance, superior shielding
properties and unusually long life under severe use.
Cables with plastic insulation should not be sub-
jected to excessive soldering-iron heat. Carefully clean
and tin the conductors and the connections to which
the conductors are to be soldered. The soldering op-
eration can then be done with a minimum of heat,
thereby avoiding any possibility of damage to the
cable.

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
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,
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 microphone, the micro-
phone cartridge leads must be interchanged (see
Figure 3). This should be performed by your dealer,
the Shure Factory Service Department, or other quali-
fied service personnel.
