Sound knowledge popularization of the integrated amplifier, before and after class

As we know , the amplifier is to amplify electrical signals . And because the majority of audio input signal is too weak to excite the speaker sound , it enables the existence of the amplifier in the market. Although there are already a lot of integrated amplifier with low price enjoys a high popularity in the market, the front and rear power amplifier is still the first choice for many enthusiasts who are in good economic situation.

The so-called front and rear power amplifier in accordance with the principle of distinction . Is to pre- preamplifier , and then level it is a power amplifier. The role of the former is the signal sent CD player , LP, or tape deck, etc. various processing and amplification in order to prepare the appropriate signals to the power amplifier , and it can have a volume control, tone adjustment functions. Then level the role of the pre- sent signal is amplified to a sufficient power required to drive to the corresponding speaker . Simply put pre- operating voltage amplification stage for the current amplification , the two separately , you can usually get a better performance than the integrated amplifier .

Another reason enthusiasts respected front and rear power amplifier class is that its free combination can often bring refreshing to enhance the effect . In most cases , before the different manufacturers , the amplifier can be used together . Although before you buy the same brand , after the class , it seems more coordinated in appearance , but the auditory point of view, is not the best choice. For instance, some brands of the class outstanding , the front of another brand and very unique. Thus each other, the different brands before , after the class together, often with a very good voice. While this mix time-consuming effort, but the search for the perfect process , it is the fans who enjoy them .
