Ball-type dual-impedance cardioid (unidirectional) dynamic microphone provides excellent voice reproduction. Its spherical grille is 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 annoying squeal or howl caused by feedback. Microphone is equipped with lockable on/off switch and an internal impedance selection socket located on XLR connector for switching between high and low impedance. Slip-in swivel adapter is supplied for convenience of stand-mounted use.
