The power amplifier is referred to as professional power amplifier, commonly known as "amplifier". It is the most basic equipment in the audio system. Its task is to amplify the weak electrical signal from the signal source (from the mixer in the professional audio system) to drive the speaker to emit sound. The power amplifier is so important in the whole sound system, so how to judge the quality of the professional power amplifier?
We can pick out a speaker with the best overall performance (vocal tunes, instrumental tunes, dance music tunes, and vocals from microphones), and use this speaker to PK professional power amplifiers. The methods and conditions for measuring pros and cons are roughly as follows:
1. Use the same sound source, the same speaker that is recognized as the best, and the same song. Use the PK machine or PK cable to instantly switch to PK to compare two professional power amplifiers. Pay attention to the changes in sound quality, timbre and music dynamics at the moment of switching. Choose the amplifier with the best performance on site.
2. If the power of the professional power amplifier is large, the sound of the speaker will be strong and powerful, full of dynamics, and the rhythm is clean and neat, while the sound of the low-power power amplifier will feel a little weaker and the sound will be slightly smaller.
3. The power of professional power amplifiers is high, and the cost is low when the power is small. In addition, using a power amplifier with enough power to push the speaker will not only make the sound good, but also make the sound system more stable. On the contrary, when the power is equal to or smaller than the speaker, the sound is easy to be distorted and unpleasant, and it is easier to burn the speaker.
4. One of the most important indicators of a good power amplifier is that the sound quality is clean and natural, with distinct layers and soft listening, while the poor power amplifier has an unclean and rough sound. In the case of relatively good sound sources, speakers, and discs (songs), the performance of professional power amplifiers is easier to identify with PK.
