Model 588SDX User Guide
2. Locate the microphone as close as practical to the desired sound source for the best gain before feedback. 3. When extra bass response is desirable, work close to the microphone. See Figure 1 for the close-up increase in low frequency output called �proximity effect�. 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 microphones practical for the particular application. 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 for closeup vocal use. 8. Avoid excessively handling the microphone to minimize mechanical noise pickup. 9. To preserve directional characteristics, do not obstruct the grille with your hand.

MODEL 588SDX
UNIDIRECTIONAL DYNAMIC MICROPHONE
The Model 588SDX is a ball-type, dual-impedance, cardioid (unidirectional) dynamic microphone that provides excellent voice reproduction. Its spherical grille is a very effective wind and pop filter which is especially good when used for closeup vocal miking. This microphone is highly suited for speech or music pickup in schools, churches, and meeting rooms. Its unidirectional polar pattern greatly reduces feedback problems, permitting operation closer than usual to loudspeakers without the annoying squeal or howl caused by feedback. The microphone is equipped with a lockable ON/OFF switch and an internal impedance selection socket located on the XLR connector for switching between high and low impedance. A slip-in swivel adapter is supplied for the convenience of stand-mounted use.

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).
