Test the Microphones

The diagnostic audio meters measure the strength of audio signals from 10 internal microphones, far-end site audio, and any device connected to the line-in audio.

The meters display audio signals for each microphone and the line-in ports. The audio signals function only when the associated input is connected.


  1. Select Diagnostics > Audio.
  2. To test the microphones, speak aloud and verify that you see signals for the four vertical microphones and six horizontal microphones.
    If no signal indication appears for a specific microphone, manually power off the camera and then power it back on.
