GENERAL
The Shure Model WH20 is a rugged, light-weight, dynamic headset microphone that provides
high-quality voice pickup. It fits securely for active microphone users, such as aerobics instructors
and musicians, with low visibility for stage appearances. The WH20 is suitable for any voice com-
munications application where comfort and reliability are required.
The WH20 has a cardioid (unidirectional) pickup pattern. This provides greater gain-before-feed-
back and isolation from ambient noise and other unwanted sound sources, such as air-condition-
ing, musical instruments and loudspeakers. A carefully shaped frequency response includes a
voice-frequency presence peak and a low-frequency rolloff to compensate for the proximity effect
inherent in cardioid microphones during close-talk operation.
An integrated elastic headband secures the headset comfortably. The headband, wireframe, and
gooseneck are adjustable to accommodate any head size or shape. The WH20 is supplied with
a foam windscreen and clothing clip.
