Line
to use a Line in device, e.g. an audio mixer for multiple microphones
or a microphone with a built-in amplifier, as audio source.
To use a professional microphone requiring 48 V phantom power, you need an external power supply and a balanced-unbalanced
converter (audio transformer) in between.
The
Microphone power
option provides DC power for an external microphone. Microphone power should only be used with
microphones that have no battery and when using the internal microphone. This setting should not be enabled when using a dynamic
or battery powered microphone. Microphone power will not harm the microphone; if you are uncertain, try switching it off and on.

relative to the full-scale input level.
