The hi-fi stereo fidelity "whole".

What is hi-fi stereo system? How to evaluate a high-fidelity audio equipment? Here will make such a concept, the so-called hi-fi stereo system is the source of the true or the voice of the system, according to the original, it is filed the live performance is the true, namely through broadcast, hi-fi system should be the same with the effect of basic close or. But to reach the effect, the only from broadcast the link is not enough, we must live performance, program recording and playback until the whole program production process with hi-fi technical requirements, including in the process of signal. Necessary Evaluating a hi-fi stereo equipment, though the fidelity of the technical indexes of many quantification, such as frequency response, the distortion degree, the transient response and signal-to-noise ratio etc, in fact they only is to test equipment which should achieve fidelity measurement indicators. Through these indicators, indirect test to understand the played signal equipment with the close degree or have much difference. A good hi-fi stereo, it should be very close to play the effect of the effect.
For sound system is one of the main components of the amplifier circuit, it is one of the fidelity of index frequency response. Almost all the power amplifiers, frequency response characteristics, and it is not completely true, that is to say it to the source of the signals of each frequency component does not give the same magnification, especially in high and low frequency ends there is bigger. In order to adjust and correct the imbalance? In the sound system in frequency band equalizer.
Go to a concert. Will the reubenites spirits, it is not only because of the beautiful melody of music? It is the play of the site and realistic. However through stereo system of recording programs are regularly tend to make people feel dull and boring. But other factors, which is an important reason of the program, put in the process of music, all the signals are caused by a signal channel signals "crowded" and mutual interference. Accordingly. In modern hi-fi stereo system? Besides using double track stereo system outside, still more stereo, surround sound track and to enhance the digital circuit and scholars of delay
Audio processing circuit. These circuit scene effect except recovery. Some people are additional effect. But whether to restore field effect or add new effect. Its purpose is to maximize made through stereo system to play, and live performance, singing effect.
