Sound > Control > Line/Mike levels


The back of this mixer has inputs for mikes (Mic in) or line audio (line in). On the front there is a toggle that lets you switch between mike and line inputs.

I hate getting too technical, but there are some things you just have to learn, nomatter how arcane they may seem. So it is with "mike levels" and "line levels."

Camcorders, VCRs, tape decks and every other type of recording device have inputs for audio. These inputs fall into two categories: mike or line. Mike and line inputs may look similar, but getting them mixed up will give you a major headache.

Because microphones put out very faint signals, mike inputs are designed to accept these weak electrical impulses and then boost them appropriately. Line inputs, on the other hand, accept a much stronger signal.

Typically, line inputs are labeled "audio in" whereas mike inputs are labeled "Mike" or "Microphone."

The only reason to bring all this this up is to ensure you keep the two separate. For example, if you plug a microphone into a "line" input, it won't work--the sound signal will be to weak. Similarly, if you plug line audio into a mike input, it will create horribly distorted audio.
