    Audio is a complete series of products, including power amplifiers; and power amplifiers are part of the audio composition.


    Audio probably includes a power amplifier, peripheral equipment (including compressor, effector, equalizer, VCD, DVD, etc.), speakers (speakers, speakers), mixer, microphone, display equipment, etc. add up to a set. Among them, speakers are sound output devices, speakers, subwoofers, and so on.


    Amplifiers are commonly known as "amplifiers" and their function is to amplify the weak signals from the sound source or pre-amplifier to promote the sound of the speakers. A good sound system power amplifier is indispensable.


    1. Audio source (equipment for playing music and songs): such as CD player, DVD player, tape recorder, etc.;


    2. Power amplifier (equipment used to drive speaker speakers): Split type (including front and rear stages) and combined power amplifier, both the front and rear stages are made in one cabinet. The front stage is generally used to adjust the sound quality equipment, generally including tuning equipment such as equalizers, karaoke machines, etc., and the latter stage is a pure power amplifier, which is a power amplifier that drives the speaker.


    3. Speakers (equipment used to play sound), divided into desktop speakers and floor-standing speakers. Generally, the common computer speaker is an active speaker, and the power amplifier power supply is installed in the speaker, so that it can be directly connected to the sound source to broadcast, and there is no need to connect an additional amplifier.
