Amplifiers and Speakers are integral to any live performance where the volume of the show needs to be at an appropriate level so that all aspects are clearly perceptible to the audience.
The amplifiers are responsible for taking electronic audio signals and amplifying them to a suitably audible level, whilst the loudspeakers take the amplified electronic audio signal and convert it to actual sound frequencies that are dispersed into the auditorium by the mechanics of the speakers.
Different sonic requirements have traditionally meant that Bass and PA amplifiers are designed and built for extreme clarity and depth. However, although guitar amplifiers also require clarity they deploy technology that overdrives the amp to create distortion and may utilise other digital processing effects such as reverb and chorus.
Speakers - just like amplifiers - are also designed and built to complement specific instruments or uses. For example, guitar speakers are voiced to enhance the mid range frequencies as this is typically where the guitar's core frequencies lie and where the "body" of the sound originates from.
