General Description

The Shure CVL is an electret condenser lavalier microphone ideal for use in speech and other applications requiring minimal visibility.

Using the Microphone

  1. Install the supplied windscreen on the microphone.
  2. Attach the microphone to a shirt collar or necktie using the supplied clip. For best results, the microphone should be 15-25 cm (6-10 in.) away from the mouth.
  3. Connect the TA4F cable to the bodypack transmitter.
