A complete audio-visual system includes many auxiliary circuits and equipment, such as audio, signal source, power amplifier, CD player, etc. The sound system will be responsible for the presentation of the audiovisual system effects from the signal source to the power amplifier, from the power amplifier to the speakers, especially the auditory experience. Even every signal line and power line affects the final listening experience of the audio system of the entire audiovisual system. Today we mainly talk about the power amplifier, how to choose more suitable for you!

Audiovisual system

1. Sound

You must experience the sound before purchasing each product. When buying an amplifier, the best way is to go to the store to experience it and see if its sound is in line with your hobby. You must know that there are many brands and models of power amplifiers on the market, and even products in the same group are very different.

Therefore, when buying an amplifier, you must first find the tone you like, then select a few clips to determine whether the scene is your favorite style, and thirdly, it depends on the power parameters, whether Mao himself can afford the matching of the speakers,

2 channel number

The number of channels is also an important part. To buy an amplifier that supports panoramic sound, you must know the number of channels. Make it clear whether you want a 7.1 or 9.1 amplifier. Most of them support 7.1.4 power amplifier products, and the built-in amplifier has about 9 channels. So when you buy it, you must see how many channels the amplifier is equipped with.

3. Function

At present, the function of the power amplifier in the audio-visual system is actually an audio-visual switch, and all audio-visual sources will be connected to it. Now that there are so many power amplifiers, each model will be different when choosing a match. At the same time, the two-zone and three-zone functions of the power amplifier are also very powerful, but some power amplifiers require external power amplifiers to achieve multi-zone functions, while others can directly call unused channels.

4. Boost

We all look forward to a richer voice. Therefore, whether the amplifier can keep up with our requirements is very important. In the matching process, we can match the power amplifier with a separate post-stage to enhance the ability to drive the power amplifier.
