Microphone Level analog audio input signals are routed via a high quality A/D and pre-amplifier, whose
Gain may be controlled using the Input Level control to achieve the desired audio reference / recording
level. Each microphone input supports +48V @ 10mA Phantom Power as a user selectable option.
To assist with reference level setup, the camera provides a color-coded Peak Level Meter in the
Graphical User Interface, with a solid vertical witness mark that indicates 0dBu / 0.775 v RMS /-20dbFS.
Peak Level Meter range is –36dBu to +20dBu (-54dBFS to 0dBFS) and provides input clip indication.
