COLLAPSIBLE MICROPHONE BOOM
The WH30 headset features a collapsible boom for shipment and storage.
Before wearing the headset, unfold the boom by rotating it away from the
wireframe until it snaps into place. Refold for storage or transportation.
WEARING THE HEADSET
Place the headset wireframe around your head so that the elastic headband
band lay horizontally across the back of your head and the ends of the
wireframe fit over your ears. You may position the elastic headband either
above or below the wireframe for the greatest comfort and stability. The blue
“SHURE” logo should face outward (see Figure 2).

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 wire-
frame earpieces may also need adjustment (see Figure 4B).
•
Adjust the tension of the elastic headband across the back of the head by slid-
ing it up or down the ends of the wireframe (see Figure 5).

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). This will also help minimize breath noise or “popping”.
CONNECTING THE WH30 TO A SOUND SYSTEM
WIRELESS APPLICATIONS (WH30TQG)
1. Connect the mini TA4F connector from the WH30 to a wireless microphone
transmitter such as the Shure T1 bodypack transmitter.
2. See the user guide for your wireless transmitter and receiver system for ad-
justing gain and other parameters.
WIRED APPLICATIONS (WH30XLR)
Connect the output of the RPM420 preamplifier to an input channel of a
mixing or recording console. Most consoles will provide phantom power to the
RMP420 preamplifier. If phantom power is unavailable, use a separate
phantom power supply such as the Shure PS1A.
WASHING THE ELASTIC HEADBAND
When necessary, remove and wash the elastic headband according to these
steps.
1. Remove the microphone cable retainer from the wireframe.
2. Slide the elastic headband off the wireframe.

3. Wash the headband in mild, soapy water and rinse it in clean water.
4. Allow the headband to air-dry thoroughly.
5. Slide the headband around the wireframe to its original position. Reattach the
cable with the plastic retainer.
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. The plastic retaining ring
will expand to allow the windscreen to slip off the microphone. If necessary,
you can expand the ring manually with a small screwdriver as you pull the
windscreen.
3. Immerse the windscreen in mild soapy water and gently squeeze it several
times.
4. Rinse the windscreen in clean water and dry it with a clean cloth or paper tow-
el. Allow it to air-dry thoroughly.
5. When the windscreen is dry, slide it over the WH30 microphone until the re-
taining ring snaps into place.
