Shure WH20 User Manual

Model WH20 User Guide

Printed in U.S.A.

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 communications application where comfort and reliability are required. The WH20 has a cardioid (unidirectional) pickup pattern. This provides greater gain-before-feedback and isolation from ambient noise and other unwanted sound sources, such as air-conditioning, 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.

WEARING THE HEADSET

Place the headset wireframe around the head so that the wireframe and elastic band are horizontal across the back of the head and the ends of the wireframe fit over and in front of the ears. Position the elastic headband either above or below the wireframe to provide the greatest comfort and stability. The white “SHURE” should face outward.
