GENERAL
The Models SM53 and SM54 are rugged dynamic cardioid microphones expressly designed for professional
applications requiring the ultimate in sound quality and
control. The performance and appearance of the two
models are very similar; however, the SM54 is
spe~ificallydesigned for use in very difficult closetalking and hand-held situations because of its immunity to "pop" and breath blasts.
Microphone Features:
Broad, smooth frequency response: provides
clean, natural reproduction of both voice and
music.
Cardioid directional pattern: optimum for wide
front working area with excellent side and rear rejection; off-axis rejection is uniform with frequency and symmetrical about axis to prevent sound
coloration and ~ r o v i d emaximum control of unwanted sound.
Integral acoustic "pop" filter on the SM54 virtually
eliminates problems of explosive speech and
breath sounds.
Minimal proximity effect: same well-balanced
sound from close talking to distant pickup.
Mechanical noise isolation: cartridge shockmounted to minimize stand and handling noise.
Bass rolloff switch: provides a gradual low frequency rolloff in applications where an overall rising response characteristic is advantageous.
Extremely low hum sensitivity: permits use in extreme hum fields.
Rugged construction: assures dependable operation with unchanging performance.
The SM53 and SM54 are designed for both stand and
hand-held use. No special precautions are required to
avoid obstruction of the rear entries, since normal
operation is assured even with only one of the small
rear entry holes open.
The reliable performance, outstanding features and
handsome appearance of the SM53 and SM54 make
them extremely versatile and ideally suited for many
demanding applications in television, radio, recording,
motion pictures and sound reinforcement. They may be
intermixed on stage and on camera with near identical
appearance and performance.
VARIATIONS

ARCHITECTS' SPECIFICATIONS
The microphone shall be a moving-coil (dynamic) type
with a frequency response of 70 to 16,000 Hz. It shall
have a cardioid directional characteristic, with
cancellation at the sides being approximately 6 dB and
the cancellation at the rear being 15 to 20 dB. The
microphone shall have an impedance of 150 ohms for
connection to microphone inputs rated at 19 to 300
ohms. The microphone output shall be -60.0 dB where
0 dB equals one milliwatt per 10 microbars of sound
pressure.
NOTE: The addition of the A53WS windscreen increases the flexibility of the SM53 microphone in a
variety of field and studio applications, by effectively
suppressing wind noise created in outdoor situations,
or by a rapidly moving boom or "fish-pole". The A53WS
has no effect on the microphone level or frequency
response. It can be used only with the SM53
microphone.
The use of the A53G pop-filter grille assembly on an
SM53 microphone converts it to an SM54 microphone.
This assembly provides protection against "pop" and
breath noise even in difficult close-talking and handheld situations. The use of the A53G pop filter grille
assembly has no effect on the microphone level and
creates only minimal changes in response (in the 4
kilohertz region) and in directivity.
