The most important part of the audio system is the speaker. The speaker is the audio output device with other components embedded in the speaker.
These components are very delicate and enable crystal clear music output. The preamplifier is the 
structural component that reduces the noise around the music.
The preamp consists of advanced sensors that will identify and multiply the intensity of the music. The music form source like the microphone and other musical instruments are multiplied in intensity and heard clearly in the large crowd.
Depending on sources
The source determines the origin of music. The power amplifier needs the source should be very clear. The power amplifier needs the dedicated stream from which the music should be originated.
The power amplifier needs the music to be filtered from other input components. The preamp will pick up the source from any other input.
The preamp is used in live recording and the background noise is reduced. The preamp can record the music from analog input also.
The source of the music is the main difference between preamp and power amp in delivering clarity output.
Combining different Signals
The music is mixed in lots of other independent sounds. This increases the entertainment in hearing the music in a social gathering. The preamp will do the mixture effectively.
The sound effects can be recorded live during the mixing. These sound effects are mixed with original sound with the same intensity.
The amplifier without preamp will play only the recorded sound. The preamp increases the liveliness in the sound.
The effects of music increased without increasing the base volume. The mixing of signals in different intensity is the main point in preamp vs power amp differentiation.
Enhancing the weak microphone signals
The preamp will pick up the sound signal from any quality microphone. The preamp decodes every bit of data in the microphone signals.
These preamps will work with any quality of the microphone. The preamps will add clarity in the audio by picking up the low-intensity microphone signals.
The preamp is used to record the sound signal s which is sent over the network. The boosting up of weak signals is a very important advantage in preamplifier vs amplifier with effective recording.
Final Words
The users must know each component of the audio system. The preamp is an important accessory in every audio system. The user clearly should understand the configuration of a preamp before changing its feature.
