How to Use a Sony Built-in Zoom Mic
Many higher-end Sony video cameras have a microphone installed known as a zoom microphone. This microphone offers you the ability to change the direction of the audio recording, focusing it on a small area directly in front of the camera or a wider area spanning either sides of the camera. To adjust and control this feature, use the menu built into the Sony video camera.
Power on the Sony video camera. Flip open the LCD screen on the side of the video camera.
Press the "Menu" button, located next to the LCD screen (it is covered by the screen, when it is closed).
Choose "Setup," then select "Audio." This brings up the audio recording information.
Choose the audio degree you want to record in. The larger the degree, the more audio is picked up from content surrounding the camera.
Press the "Menu" button to accept the audio settings change.
