Mic Level is the lowest signal level which travels through an XLR connection and requires a preamp to be raised to Line Level. This should be used whenever using a microphone with your interface.
Line Level is the highest signal level which travels through a TRS connection. This is the standard type of signal and should be used when connecting any non-instrument pieces of hardware to your interface (i.e. an outboard preamp or processor) or instruments that output line level (synths, keyboards, drum machines etc)
Instrument Level is the most variable level signal which will travel through a TS connection and will also require a preamp to be raised to Line Level. This should be selected whenever connecting an instrument such as a guitar or bass guitar directly to your interface.
