Everyone must be aware of the basic purpose of using the amplifier, which is used to receive weak signals and increase the amplitude to drive the speaker.
A power amplifier is an electronic device that receives electrical signals at the input level and then enlarges them to increase power.
Power improvement can be achieved by increasing the input signal voltage alone.
This power amplifier is always used to power the output of any stereo speaker, relay or motor.
These directly obtain the amplified energy required for the input signal from the AC wall socket that connects them.
The perfect amplifier is used to get energy from the AC socket and convert it into a useful amplifier.
However, in reality, there is no amplifier that works effectively and always wastes some energy from the wall socket.
This energy later dissipated in the form of heat, which is considered bad for any electronic product.
This heat dissipation is one of the biggest enemies of electronic equipment, so it is very important to make sure that these devices have enough airflow exhaust or convection cooling equipment.
Want to know what are the basic components of the power amplifier, which are the power supply, input level and output level.
Here, the power supply converts the alternating current from any electrical signal on the input socket to direct current.
The power supply is used to send the DC signal to the input level and then to the output level where the actual signal is amplified.
Later, this output level is connected to the speaker.
The power amplifier ratings are calculated based on Watt, which gives the idea of the approximate maximum power output they produce.
These are mainly transistors.
An amplifier in the form of a vacuum tube for internal circuits.
These are usually smaller than other tubes.
Corresponding to the style, the efficiency is higher, and the cost is higher.
These three different types of audio systems are widely used according to user needs.
The output stages of these power amplifier types describe the design of the output circuit.
The distortion level of class A amplifiers is very low.
The price of Class B amplifier is much lower than that of any class A amplifier, and the overall operation efficiency is very high.
Class AB amplifiers have the combined properties of Class A and Class B.
This class AB product is most widely used in home stereo systems.
Attention should be paid to ensuring that the power amplifier does not exceed the wattage capacity of the connected speaker.
