During AVCHD recording, a 5.1 channel built-in microphone captures active sounds coming from five directions, so you can experience your home movies the way you experienced them while recording. Level meters on the LCD panel provide visual monitoring of each channel's levels.
Note: The 5.1 channel audio is only available when recording in AVCHD, so it is not available for UHD 4K recording, which uses the XAVC S codec.
