Matching Levels:
It's crucial to match a device to the correct input, since there's no real technical tolerance for mistakes. For example: Connecting a microphone to a line-level input will result in almost no sound at all, because the mic-level signal is too weak to drive the line-level input;   Connecting a line-level source to a mic-level input will cause the sound to be loud and distorted because the line-level signal is much stronger than what the mic input will accept.
