MODEL 515SDX

UNIDIRECTIONAL DYNAMIC MICROPHONE

The Shure Model 515SDX is a dual-impedance, cardioid

(unidirectional) dynamic microphone that is suitable for

speech pickup in schools, churches, and meeting rooms. Its

unidirectional polar pattern greatly reduces feedback.

The 515SDX includes a locking ON/OFF switch and an in-

ternal impedance selection socket mounted on the XLR con-

nector for switching between high and low impedance. A

slip-in swivel adapter is supplied for stand-mounted use.

Features

Rolled-off low-frequency response combined with a

smooth high-frequency rise for clear and intelligible

voice pickup

Symmetrical cardioid pickup pattern minimizes feed-

back

Neodymium magnet for high signal-to-noise ratio

Shock-mounted cartridge that minimizes handling noise

Lockable ON/OFF switch

Dual impedance selectable by internal socket

Slip-in swivel adapter for stand-mounted use

Three-pin professional audio connector, the industry

standard, for maximum interchangeability of cables

Tough, die-cast grille resists wear from constant use and

handling

Field serviceable and backed by the Shure 2-year

warranty

BASIC RULES FOR MICROPHONE USE

1. Aim a directional microphone toward the desired sound

source (for instance, a talker or singer) and away from

undesired sources (such as loudspeakers).

2. When extra bass response is desirable, work close to the

microphone. During closeup use, the low frequency out-

put will increase. This increase is called “proximity ef-

fect.” Refer to the frequency response curve (Figure 1).

3. Locate the microphone as close as practical to the de-

sired sound source to get the most gain before feedback.

4. Do not pick up the same sound source with more than

one microphone. Keep the distance between multiple

microphones at least three times the distance from each

source to its intended microphone.

5. Use the fewest number of microphones possible.

6. Locate microphones as far as possible from acoustically

reflective (hard or smooth) surfaces.

7. Add an external windscreen when additional pop

protection is needed (outdoors in windy conditions or

closeup vocal use, for example).

8. Avoid excessive handling of the microphone; doing so

will minimize mechanical noise pickup.

9. Keep the grille unobstructed; doing so will preserve the

microphone’s directional characteristics.
