Adjusting the input level (gain)

Set the microphone’s input level in a quiet environment in order to achieve maximum suppression of off-axis noise.

For natural voice/volume

  1. Speak into the microphone with a natural volume and watch the level indicator.
    • The LED is solid green. The peak level is within the tolerance range. Proceed to step 6.
    • The LED is solid yellow. The microphone is overdriven.
  2. Turn the knob counterclockwise to lower the gain.
  3. Speak into the microphone again and observe the level indicator.
  4. Repeat the steps until the LED turns green.

For adjusted voice/volume

If the LED is yellow even with quiet tones, the microphone sensitivity may be set too high on the device you are using. Adjust the microphone sensitivity on your device and repeat the previous steps.
  1. Speak into the microphone with a loud voice to simulate overdrive and determine the peak level limit in your intended situations.
    • The LED is solid green. The peak level is within the tolerance range.
    • The LED is solid yellow. The microphone is overdriven.
  2. Turn the knob counterclockwise to lower the gain.
  3. Repeat the steps until the LED turns green.
  4. If necessary, simulate several situations in which you change your chromatic range and the distances to the microphone.
  5. Adjust the input level so that the incoming signal remains within the tolerance range in all intended speech or singing situations as indicated by the green LED.
