Internal Microphones
The internal microphones can be used to record a reference track, sometimes also referred to as
"scratch track". Some software tools can synchronize the master audio to the image using the reference
track. The signal of the internal microphones is recorded to audio channels 3 and 4. The audio
recording level of the internal microphones is fixed, with the left microphone (channel 3) using a +18dB
higher gain than the right microphone in order to cover a wide range of audio levels.
