For converting an audio signal, Audio mixer is used. It is nothing but electronic equipment which is mainly used for varying, steering audio signals. This is also called as soundboard. Also the soundboard alters the beat, pitch or it may alter the sound signals. The soundboard gives small alteration in every new step. The soundboard consist of different types of applications is present. The soundboard is used to merge signals from two different microphones so this is the example for the soundboard. As a result the merged sound of soundboard is heard only by single set of speakers.

The above example is helpful to prepare the two actions is heard during the single set of speakers.

The audio mixture frequently has the subsequent mechanism for the input section:

1.   Input jacks/Microphone pre-amplifiers: The section during the sound enters the mixer .Input jacks/microphone pre-amplifiers used to block the microphones and pre-amps.
   

2.   Basic input controls: The basic input controls are used to control the pitch, bass, treble and so on of the input signals. Every input slot approaches with some guide controls about it. The differences in the sound can be used by the skilled professional. By the help of settings to rectify the small differences in the sound before the sound gets recorded. The basic input controls also have the most hindrances from external sources. Therefore it must be control properly.
   

3.   Channel Equalizers: The small adjustments in beats, amplifying the low pitch spots to make channel equalizers clear and audible. The channel equalizers are precious in controlling the pitch of music being played. Many things complete by here.
   

4.   Routing section: The routing section is used to transform the audio signals to the output devices, for example of routing section is recording devices or speakers. The routing section is used to find the music that is placed and it should be heard from the speakers in various locations. For example in ordinary two speakers setup, routing section is to decide whether in which portion the music would be heard during the left speaker and it is used to determine which portion must be heard during the right speaker. For this purpose the routing section is used.
   

5.   Input and subgroup faders: The mixers of each and every channel have potentiometer. The potentiometer that is controlled by the sliding volume control to regulate the amplitude at the end of the mixture of channels. The input and subgroup faders controls only single channel of audio or it will make some small adjustments. That is possible over in this Input and subgroup faders.
   

In some audio recording setup the main components is the audio mixer. The skilled professionals can judge lot of errors in budding artists that time they act like a skilled artist. The input and subgroup faders service need to setup cautiously to make sure of long term and cost effective service. So this is the main mechanism of input and subgroup faders.
