Connection to: mic-level input
For dynamic microphones an XLR input is sufficient, for condenser microphones the input must provide phantom power (usually marked with "48", "+48V" or the like).
Connection to: Line-level input
Either stereo input (mostly mini jack) or two mono inputs (2x jack or cinch). A twin cable would come in handy.
Connection to: Instrument-level inputs ("Hi-Z"/Guitar/Instrument).
Do not connect to the line input, as that would lead to a much thinner, weaker and less powerful signal and more unwanted noise. If the interface has no instrument input, you will need a DI box.
