Model 5575LE is a cardioid type unidi-
rectional moving coil dynamic microphone
providing wide-range high quality repro-
duction of sound. The true unidirectional characteristic of
the “Unidyne” obtained by the “uniphase” principle* pro-
vides highly satisfactory operation under adverse acoustic
conditions where a conventional microphone would be practi-
cally useless. (See “Acoustic Considerations”).
The microphone has a specially designed moving sys-
tem containing a new type moving-coil element, operating
in conjunction with a high flux magnet in the magnetic
circuit providing high efficiency and smooth peak free re-
sponse from 50 to 16,000 cycles. The rear response is down
approximately 20 dB due to the “uniphase” unidirectional
acoustic network.
The housing is modern in design with attractive
streamlining and grille treatment. The head tilts through
an angle of 90° to permit aiming at the source of sound
for best pickup. A built-in cable connector and attractive
desktop stand are provided.
Model 5575LE is suitable for high quality
public address, broadcasting, recording
and similar applications. The true unidi-
rectional characteristic of the “Unidyne” provides an easy
solution to the feedback problem in reverberant locations,
facilitates orchestral placement, permits best utilization
of space in small broadcast studios, and allows practically
complete exclusion of unwanted noises. The swivel allows
the head to be tilted through an angle of 90° permitting
the microphone to be aimed at the source of sound.
The 5575LE is unusually rugged and is practically im-
mune to the effects of moisture, temperature and mechanical
vibration.
All microphones have the standard 5/8”-27
thread and may be mounted on any Shure
desk, banquet, or floor stand. Shure
floor stands are especially recommended because of the ef-
fective isolation against floor vibration which they pro-
vide. The furnished Shure S36B desk stand provides an el-
egant and functional desktop solution.
Model 5575LE terminates in a male XLR
style connector which mates with any XLR
cable for direct connection to a high-
quality microphone preamplifier. The furnished S36B desk
stand includes a right-angle XLR cable.
Model Impedance Cable Furnished
5575LE 250-300 ohms 1.5 ft. three-
conductor XLR type
This low impedance model 5575LE is suitable for applica-
tions where long cable lengths are required. The permissi-
ble line length is practically unlimited since neither the
level nor the frequency response is appreciably affected by
reasonable lengths of line.

“Unidyne” Dynamic Microphone
DATA SHEET
55 Series “Unidyne” Microphones
(Cardioid-Type Unidirectional Moving-Coil Dynamic)
The microphone should be placed in its
operating position before turning up the
volume controls of the amplifier. Jarring
or excessive moving of the microphone should be avoided,
however the patented internal pneumatic shock mount system
effectively reduces mechanically-borne vibrations while the
system is in operation in order to minimize the production
of undesirable noises.
No special precautions beyond ordinary care are nec-
essary in the operation of 55 Series Dynamic Microphones.
They will operate efficiently and dependably under all or-
dinary conditions in hot and cold climates. To retain the
full strength of the highly efficient permanent magnet and
to maintain alignment of the structure, dropping or other
severe mechanical shocks should be avoided.
The expression “cardioid type” response
simply means that the horizontal polar
characteristic approximates a cardioid of
revolution. There is a wide, useful pickup
angle at the front of the microphone while the response at
the sides is down 6 dB from the front response. The rear
response in practical cardioid type microphones is down of
the order of 20 dB from the front side response. The pat-
ented “Unidyne III” microphone element fulfills these re-
quirements over a broad range or frequencies.
The true unidirectional characteristic of “Unidyne”
elements should not be confused with the relatively slight
directional effect at high frequencies only which can be
produced by baffle effects in the conventional pressure
microphone.
