On each input the mixing desk provides preamplification, which amplify the microphone level signals to line level; equalization, which provides the means to contour the tonal balance of each microphone; and level control, which allows the operator to adjust the relative level of each microphone individual. The design musical instruments and how they project in an acoustic sp… Sound systems often include many more types of signal processors, which are used to effect change on any number of different audio signals. In a small room with padded walls (heh heh), we are less concerned about intelligibility as the padding will tend to absorb sound rather than reflect it; rooms that are rather nonreverberant are usually termed "dead.".
