The role of a power amplifier

1. Front amplifier

 

The main function of the front amplifier is to process the program signals transmitted from the signal source and amplify the voltage before output to the rear amplifier. It is like a railroad fork in the road. It controls which sound source signals are connected to the amplifier and which are disconnected from the amplifier.

 

2. Rear amplifier

 


Improve sound quality: In addition to increasing volume, power amplifiers also improve sound quality. However, it should be noted that only by properly installing the power amplifier can it effectively improve the sound quality of our sound system.


will come with some power amplifier, but because it can not meet the needs of some people will install a power amplifier.many audio equipment Amplify the volume: the power amplifier most main function is used to amplify the volume, is generally used in the household audio and all kinds of audio equipment on the. Power amplifier is also relatively simple to install,


The power amplifier of the rear stage is the part that performs simple power amplification. Its function is to amplify the signal from the front stage as faithfully as possible. Our requirement for the rear stage is that the amplification factor should be as high as possible while the distortion degree of the amplified signal should be as low as possible. In addition to amplifying circuit, there are also designed to protect the circuit, such as short circuit protection, overvoltage protection, overheat protection, overcurrent protection, etc.

 

3. Used in military field

 

One of the most important functions of power amplifiers used in military applications is to amplify captured signals. Since the sound signals we capture are so small that it is difficult to get useful information, we can use power amplifiers to amplify the signals.

 

4. The role of audio power amplifier

 

There are two kinds of audio amplifiers: one is dedicated to audio amplifier operational amplifier, it has good performance in the audio range (mainly frequency response characteristics and distortion characteristics, good audio amplifier these two characteristics are very good), generally used for audio pre-amplifier stage.


The other is the audio amplifier, that is, the power amplifier circuit, used for the sound of the driver stage, can drive the power of the loudspeaker or sound, so that the sound.
