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.

The result of this unidirectional characteristic is a

complete elimination of acoustic feedback at volume levels

which would cause considerable feedback with conventional

semidirectional microphones. In practically all cases it

is possible to increase loudspeaker levels when a Unidyne

microphone is installed. By directing the dead side (rear)

of the microphone towards the audience or other source of

interfering sound, pickup can be concentrated on the de-

sired source. Reverberation energy pickup is decreased ap-

proximately two thirds. The microphone can be placed close

to reflecting surfaces without objectionable effects if the

rear side of the microphone is toward the reflecting sur-

face. This is particularly valuable in small broadcast stu-

dios.

It is desirable to experiment with microphone place-

ment and orientation in order to secure the greatest ben-

efits from the unidirectional characteristics.

Transducer Type:

Electrical response is provided by a moving coil ele-

ment operating in conjunction with a high flux magnet

in the magnetic circuit.

est rejection at 180 degrees from the front of the

microphone.

signal directed on-axis from two feet, or 58 dB below

1 volt per Pascal when loaded with 1000 ohms.

wave, the resulting voltage output relative to ground

at pin 2 of the XLR connector is also positive.
