COLLAPSIBLE MICROPHONE BOOM

Before wearing the headset, unfold the collapsible boom until it snaps and locks into place. Refold for storage or transportation

WEARING THE HEADSET

Place the headset 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.

ADJUSTING THE HEADSET

If the headset feels loose or uncomfortable, carefully bend the sides of the wireframe to make it tighter or looser. The angle of the wireframe earpieces may also need adjustment.
Adjust the tension of the elastic headband across the back of the head by sliding it up or down the ends of the wireframe.

POSITIONING THE MICROPHONE

IMPORTANT: For maximum gain before feedback, position the gooseneck so that the microphone grille (silver side) is within 25 mm (1 inch) of the right corner of the mouth. Do NOT position it directly in front of the mouth.

USING THE CLOTHING CLIP

The supplied spring-loaded clothing clip secures the microphone cable to the user’s clothing and keeps it from becoming entangled with the user’s movements.

OPERATION

Connect the WH20 to a wireless microphone transmitter or a balanced wired microphone input.
NOTE: The WH20 is a dynamic microphone and has inherently lower output than condenser microphones. The transmitter gain may need to be increased to compensate for the WH20’s lower output.

WINDSCREEN

Install the supplied windscreen to avoid breath noise or “popping” and to protect the WH20 from dirt and moisture.

WASHING THE FOAM WINDSCREEN

When necessary, clean the windscreen in a mild soapy water solution.

IMPORTANT:

Always remove the windscreen before cleaning. Allow it to air-dry thoroughly before re-installing

WASHING THE ELASTIC HEADBAND

The elastic headband can be removed from the wireframe and hand-washed in a mild soapy water solution. To remove and wash the headband, follow these steps: Remove the microphone cable retainer from the wireframe. Slide the elastic headband off the wireframe. Wash the headband and allow to dry thoroughly. Slide the headband around the wireframe to its original position. Reattach the cable with the plastic retainer. Note that the elastic headband supplied with the WH20 is not a standard size; headbands purchased in stores are too long for this application.
