Five differences between digital power amplifier and analog power amplifier by K

With the continuous update and development of the power amplifier technology, the KTV power amplifier has two kinds of digital power amplifier and analog power amplifier at present. These two types of power amplifier are often compared, which is good in the end? And KTV power amplifier, the most useful is singing and listening to music. Like these mainstream products on the market, each has its own characteristics.

In fact, for KTV power amplifier, the standard of final judgement lies in the quality of sound quality. So in a few ways in the end? Here is the Jazz sound manufacturer to introduce the difference between digital power amplifier and analog power amplifier.

1, classification of equipment

For high grade equipment, the sound quality of analog power amplifier is better than that of digital power amplifier. But this is not absolute, for example, the MP3 player uses digital power amplifier.

2. The difference between the fidelity of the power amplifier

Digital power amplifier is very good in reducing sound quality, high fidelity, and better effect on the field. Analog amplifier output sound and acoustic is there is a certain degree of difference, through the post modification.

3. The difference of sound quality

Digital power amplifier analog amplifier clear sound quality and comfortable, the home theater, each one has his good points, recommend the use of digital power amplifier is better, if only to enjoy music, with the analog amplifier suggested that better sound effect.

4, sound image location

The output signal of analog power amplifier is not consistent with the input signal phase, and the output power is different from the different phase distortion. The output signal of the digital power amplifier is exactly the same as the input signal phase, so the audio and image positioning of the digital power amplifier should be accurate.

5, the difference of distortion

Because the digital power amplifier works only in the switch state, it will not cause the cross distortion. The analog B class power amplifier is over zero distortion.
