Vocal Microphone
The Shure Specialty to General Communications Microphone Series 588 SDX 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.

The 588-SDX 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.
Controlled low-frequency response combined with a smooth high-frequency rise for clear and intelligible voice pickup
Symmetrical cardioid pickup pattern minimizes feedback
Spherical grille provides effective filtering out of breath noise and popping when used for closeup vocals, and of wind noise when used outdoors

Type Dynamic (moving coil)
Frequency Response 80 to 15,000 Hz
Polar Pattern Cardioid (unidirectional) symmetrical about axis
Impedance LO Z= Microphone rated impedance is 150 O (270 O actual) for connection to microphone inputs rated low impedance; HI Z= Microphone impedance is “High” for connection to high-impedance microphone inputs
Sensitivity (at 1,000 Hz) Open Circuit Voltage*; LO Z= – 55.5 dBV/Pa (1.7 mV); HI Z= – 37.0 dBV/Pa* (14.1 mV); *1 Pascal=94 dB SPL
Phasing Positive pressure on the diaphragm produces positive voltage on pin 2 relative to pin 3 in both HI Z and LO Z modes
Switch Built-in ON/OFF switch, lockplate to lock switch ON
