Structure Audio Mixer

Audio mixing consul Yamaha 2403 audio mixing console for live performance applications
Line inputs (input) is usually divided into several sections:
§ input jacks / amplifier front of the microphone (mic preamps)
§ basic input controls
§ Channel EQ (High, Mid high, medium and low)
§ Routing Section including Direct Outs, Aux-sends, pan control and subgroups that address
§ Input faders
§ subgroup faders
§ Output controls including Master level controls, EQ and / or routing matrix
In consul-beater did yamaha next few sections are given color codes to facilitate quick identification by the operator.
Depending on the type mixernya, whether it's mono or stereo input has an entry according to your own settings for each input. In most mixers, each channel has an entry type XLR, RCA Jack input size or 1/4 inch.
Basic input controls
Below each input, there are usually several rotary controller (knobs, pots). The first one is generally called gain adjustment or trim. Entry will set the signal from external equipment and controls, and adjusts the amount of gain or attenuation of the signal necessary for proper signal level to the next process. In this step, wherein most of the noise and interference have a major impact, which generally have a microphone gain of approximately 50 dB, the gain of this magnitude may be impaired.
XLR balanced inputs and connectors, such as type, Tip-Ring-Sleeve (TRS) jacks 1/4 inches, this will reduce the interference problem. Then be many entry points after the buffer / level gain, whereby if there is send or return from outside the processor will only affect the channel. entry point (insertion points) are typically used to control the effects of signal amplitude, as the noise limit (noise gate), pelebar (expansion) and compression (compressor).
Assist send routing
The auxiliary sending a signal that directs separate entry for that one auxiliary track can be used with external equipment. . Auxiliary sends, whether it is pre-fader or post-fader, where the level of a pre-fade send is set by Auxiliary control shipping, whereas post-fade sends depend on the position fadernya channel. . Auxiliary sends can also send signals to external processors, such as resonance, which can then be fed back to go through another channel or return incorporated into existing in the auxiliary mixer. Pre-fade auxiliary sends can be used to provide a mixture of monitoring the musicians on the stage, wherein the mixture monitoring is independent of the main line mixing.

Channel EQ
Setting the channel is still the channel EQ. These settings adjust the tones of equalization tone low frequency (bass), the midtone (midsize) and high tones (treble). In most of the width consul mixture (24 channels or more), generally has equalizing scanning one or more frequency bands is called parametric equalizer. Mixer with a smaller size to have any or any this equalizer. Equalizer also set the frequency level set Siara cliping not happen that would interfere with the sound quality of the resulting channel. mixer still has a few common equalizer controls the output level.
Subgroup and mix routing
Each channel has a mixer potentiometer audio cone-shaped rotary or sliding potensio meter to control the volume level of each channel to make it easier. The number of entries to determine how well the existing audio faders. Then, from each channel that is embedded in the range play "mix", or be subdivided into several sub-mixture. The complexity of this arrangement depends on what applications will be used mixer. Also, the mixer is provided "insertion point" for each bus or also in the total mix.
