Wearing the Microphone

  1. Install the windscreen on the microphone boom.
  2. Place the headband around the back of the head, with the boom on the left side.
  3. Place the microphone at the corner of the mouth. To decrease pops and plosives, avoid placing the microphone directly in front of the mouth

Maintenance and Cleaning

  • If the microphone is exposed to perspiration, remove the windscreen and gently wipe the microphone underneath with a damp, non-abrasive cloth. Allow the microphone to air dry before replacing the windscreen and storing.
  • The windscreen can be washed with a mild antiseptic, and should be fully rinsed and dried before reinstalling on the microphone. Do not use alcohol-based disinfectants.
