Models WH30TQG and WH30XLR User Guide MODEL WH30 CONDENSER HEADSET MICROPHONE WH30XLR ONLY 2003, Shure Incorporated 27D3121 (Rev. 4) Printed in U.S.A.
English INTRODUCTION The Shure Model WH30 is a light yet rugged headset microphone. Designed for vocalists and instrument-playing vocalists, the WH30 utilizes a high quality electret-condenser cartridge suitable for all applications where mobility, comfort, low microphone-visibility, and high sound quality are required. Because of its cardioid (unidirectional) pickup pattern, the WH30 provides isolation from extraneous sound sources and high gain-before-feedback.

English FIGURE 2. WEARING THE HEADSET FIGURE 3. POSITIONING THE MICROPHONE ADJUSTING THE HEADSET • If the headset feels loose or uncomfortable, carefully bend the sides of the wireframe to make it tighter or looser (see Figure 4A). The angle of the wireframe earpieces may also need adjustment (see Figure 4B). • Adjust the tension of the elastic headband across the back of the head by sliding it up or down the ends of the wireframe (see Figure 5).

English FIGURE 5. ELASTIC HEADBAND ADJUSTMENT USING THE CABLE RETAINER AND CLOTHING CLIP Use the cable retainer on the wire frame of the headset to position the microphone cable as desired. The supplied spring-loaded clothing clip secures the microphone cable to the user’s clothing to help avoid entanglement. POSITIONING THE MICROPHONE For maximum gain-before-feedback, position the microphone and boom so that the microphone is within 13 mm (1/2 inch) of the right corner of your mouth (see Figure 3).
WASHING THE FOAM WINDSCREEN The foam windscreen protects the WH30’s microphone-element from dirt and moisture. When necessary, it can be removed and cleaned in a mild soapy water solution. Important: Never clean the windscreen with any liquid solution without first removing the windscreen from the microphone boom. 1. Hold the windscreen loosely by the plastic retaining ring at its base. 2. Gently pull the windscreen away from microphone.
