People who want to enjoy the pleasure of music with ultimate sound effects then an amplifier suits their need by boosting the sound system.
Amplifier is the equipment operated to increase the amplitude of signal.
There is a wrong belief among people that an amplifier is the stereo component or musical equipment.
But it is only the small representative of amplifier.
You can come across amplifier in radio, television, computer, CD players etc that uses a speaker to produce the sound.
The various technical terms in amplifier are Gain- ratio of output to input power (decibels), bandwidth - frequency range, satisfactory performance is obtained by selecting over the range.
Full range audio amplifier will have 20Hz to 20KHz.
Finally the efficiency of amplifier is how much of the input power applied to deliver the amplified output.
Whenever the efficiency is greater not much of the energy loss occurs thus making it cool.
Various types of amplifier include Class A - less efficient of about 25% Class B - highly efficient but it is quite impractical because of increased distortion and less quality too.
Modern class AB - efficiency in the range of 35-55% Switching class D - 90% efficient but not so impressive.
Class C-F - highly efficient.
Sound energy generates vibration in atmosphere which helps in the migration of air particle which in turn tends the nearby air particle to move thereby carrying the pulse of vibration to the ears.
Ears pick up the fluctuations in air pressure and translate it to electrical signal.
Finally brain processes them.
The same way electronic sound equipment works.
Translators are used for transformation of signal from one form to another and finally the original form is put back.
Encountering of minute fluctuations is highly depended on the sensitivity of microphone's diaphragm.
Sound is then produced by pushing the speaker back forth, which is quite difficult.
So the amplifier is placed to boost the sound signals.
Amplifier's job is the collection of weak signal and boosting it to generate powerful signal.
It works by generating new output signal based on the input signal.
The generation of output circuit is by power supply rendered from battery (AC).
The flow of charge alters the pathway thereby converting AC to DC.
In case of DC charge flows in same direction.
Power supply smooths the current thereby giving uninterrupted signal.
This working of output circuit enables the speaker cone to move.
In input circuit electrical audio signal is recorded on tape or made to run in microphone.
This load in input circuit modifies the output circuit by applying varying resistance to output circuit.
This automatically creates voltage fluctuations of original audio signal.
But the work load in amplifier is greater so it calls in for the presence of pre-amplifier to boost the signals.
Pre-amplifier sends stronger output signal to power amplifier.
Surround effect is obtained by multi-channel speaker system employing more than three directions for the sound to reach the ear.
Home theater system is well furnished with surround effect where amplifiers employed to ultimately boost the sound system.
Apart from this amplifiers have various traits like reverb unit, jazz, chorus, tremolo etc.
Clear tone, sharp treble, warm sound with huge intensity is attainable with help of amplifier.
The superior amplification solutions with immense quality, lovable, warm full quality sound, depth of lightness, energetic is assured in the amplifier.
