-  In addition to the function of driving loudspeaker reinforcement by the amplified signal of an ordinary power amplifier, Can also effectively suppress the scene roar, to ensure the quality of voice transmission, even in the environment is poor occasions, but also can greatly suppress the roar back to protect the audio equipment will not be burned out because of the roar.

-  According to function, according to different functions, it has pre-amplifier (also known as the front stage), power amplifier (also known as the post stage) and combined amplifier. Power amplifier used to enhance the signal power to drive the sound of an electronic device. No signal source selection, volume control amplifier.

-  According to the different types of power amplifier tubes, it can be divided into duct machine and stone machine. The stone machine is an amplifier that uses transistors. According to different uses, it can be divided into AV amplifier, Hi-Fi amplifier. AV power amplifier is specially designed for home theater purposes and the amplifier generally have more than 4 channels and surround sound decoding function, and with a display screen. The main purpose of this kind of power amplifier is to create a real movie environment sound effect and let the audience experience the cinema effect.

The Role of Power Amplifier

The function of the power amplifier is to amplify the weak signal from the sound source or the pre-amplifier and promote the sound of the speaker. A good sound system power amplifier is indispensable.

Power amplifier, is the largest family of all kinds of audio equipment, the role is mainly to amplify the weaker signal input from the audio source equipment, and generate enough current to promote the speaker to play the sound. Due to the consideration of power, impedance, distortion, dynamics and different use ranges and control adjustment functions, different power amplifiers are different in internal signal processing, circuit design and production technology.
