Professional Amplifiers​ In terms of their main use, power amplifiers can be divided into two main categories, namely dedicated power amplifiers and civilian power amplifiers. Power amplifiers used in stadiums, movie theaters, dance halls, conference halls, sound reinforcement in public places, and recording monitors generally have some unique requirements on their technical parameters. a power amplifier or professional power amplifier.

To make a reasonable configuration between Professional Amplifiers and speakers, in general, the output power of the power amplifier should be 1.5-2 times the rated power of the speakers. For example, if the rated power of the speaker is 200w, the output power of the Professional Amplifiers should not be lower than 300-400w. Such a configuration can not only ensure that the sound will not be distorted, but also reduce the possibility of speaker damage.

Both AV amplifiers and Hi-Fi power amplifiers have very strict requirements on Professional Amplifiers and have clear requirements in terms of output power, frequency response, distortion, signal-to-noise ratio, output impedance, and damping coefficient.

Professional Amplifiers and speakers must pay attention to two problems when matching, one is impedance matching, and the other is power matching. If the two are matched reasonably and accurately, this can not only ensure the high-quality reproduction of the speaker sound without distortion, and give people a beautiful enjoyment, but also ensure the safety of the speaker. On the contrary, it will not achieve a good sound effect, and it is easy to damage the speaker, especially the tweeter of the speaker.

Professional Amplifiers refer to amplifiers that can produce the maximum power output to drive a load (such as a speaker) under a given distortion rate. Professional Amplifiers play a pivotal role in the "organization and coordination" of the entire audio system, and to some extent determine whether the entire system can provide good sound quality output.

Class D (digital audio power) Professional Amplifiers are a kind of input analog audio signal or PCM digital information converted into PWM (pulse width modulation) or PDM (pulse density modulation) pulse signal, and then controlled by PWM or PDM pulse signal High-power switching device on/off audio power amplifiers, also known as switching amplifiers.
