Say result is put simply a kind of power that expands sound magnifier, expand sound purely only, some power is put inside still "equalizer" it is to do sound effect better listen to some, sound box is the box that has horn above! Amplifier commonly known as "amplifier" his effect is to come from the sound source or before the weak signal amplifier to expand, promote the sound box. An excellent sound system and the effect of the power amplifier is very important.

According to use the different OF YUAN EQUIPMENT, POWER PUT HAS AGAIN "BRAVERY MACHINE "[ELECTRON tube POWER PUT]," STONE MACHINE "[transistor POWER PUT],"IC POWER PUT "[integrated circuit POWER PUT]. In recent years, because of the use of new technology and new concepts in the bile machine, the vacuum tube, an old vacuum equipment, shines brightly again. Its beautiful sound makes many burn friends bow down. I mean, every serious enthusiast has one.

"IC Amplifier "because his sound is not as good as that of the other two amplifiers, we rarely see him in HI-FI amplifiers. Power expansion in general can be divided into three categories of "professional power amplifier", "civil power amplifier", "special power amplifier "." Professional power amplifier" is generally used for conference, performance, hall, hall, field, hall of the amplification.

In terms of planning, the output power is large, the maintenance circuit is perfect, and the heat dissipation is excellent. The timbre of most "professional amplifiers" is hard and hard to listen to when used for HI-FI playback. Civil power amplifier "specific classification has "HI-FI power amplifier ""AV power amplifier ""KALAOK power amplifier" and the various common functions set in one of the so-called "inductive power amplifier ".
