The Function of Power Amplifier in Sound System

The Function of Power Amplifier in Sound System

In the field of multimedia speakers, the concept of independent power amplifier first appeared in 2002. After a period of market cultivation, in 2005 and 2006, the new design idea of this multimedia speaker has been widely recognized by consumers. Major speaker manufacturers have also introduced new 2.1 speakers designed with independent power amplifier, thus setting off wave after wave of "independent power amplifier" panic buying boom. In fact, from the sound quality of the speaker, it will not be greatly improved because of the design of the independent power amplifier. The independent power amplifier can only effectively reduce the influence of electromagnetic interference on the sound quality, and is not enough to cause a considerable improvement in the sound quality. Nevertheless, the independent power amplifier design still has many advantages that ordinary 2.1 multimedia speakers do not have:
