Sound System : Basic Device

Sound system for the live performace and the recorder had two main components that is: microphone and mixer. Microphone was used to convert voice signal to electric signal. Mixer was used to combine all these signals.
The signal from mixer output is connected with amplifier.
Amplifier will strengthen this signal in being given to speaker.
Speaker will change this signal into the acoustic wave as the sound.

Afterwards in the system of the voice order also was gotten the processor that generally is connected around mixer and amplifier.
The processor was used to increase the quality of the signal audio.
The most general processor was used that is equaliser, effect, and the compressor.
Equaliser basically is the control collection of the tone that could raise or reduce the frequency of the signal audio specifically.
Effect is used to give special effect of the sound, like reverb (the voice reverberated) and delay (gave the postponement of the signal).
The signal that was too strong until passing the limit that was given to the compressor will be reduce.
In this case, the compressor could help prevented damage in speaker.
