U.S.A.

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~ifically designed 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

~rovide maximum control of un-

wanted 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 shock-

mounted to minimize stand and handling noise.

Bass rolloff switch: provides a gradual low fre-

quency

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 opera-

tion 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 Models and

SM53-CN and SM54-CN: Same as models SM53

SM54, respectively, except supplied with professional three-pin audio connector on equipment end of cable. (See Specifications for details on cable.) Models SM53-LC and SM54-LC: Same as Models SM53 and SM54, respectively, except supplied without cables.

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.

The microphone shall have a two-position Response

Selector switch. One

~osition ~rovides a flat resDonse and the second position provides gradual low frequency rolloff.

The microphone shall be provided with a swivel

adapter and a

6.lm (20 ft), two-conductor, shielded cable equipped with a professional three-pin audio connector designed to mate with Cannon XL series, Switchcraft A3 (A.G.) series, or equivalent connector. The microphone swivel adapter shall mount on a stand having

length and 38 mm 194 diameter for the

5/8"-27 thread.

The overall dimensions shall be 182

mm (7-=/32 in.) in

(1 % in.) in diameter for the SM53 and

mm (7% in.) in length and 44 mm (1% in.) in

SM54.

The microphone shall be a Shure Model SM53, SM54,

or equivalent.

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 kilohertz region) and in directivity.
