The automobile sound as the flow of the music hall to tour alone became a kind to enjoy. Regardless of whether the car audio fancier, magnetic face these filled withmetal texture of the equipment will be deeply attracted by its unique. But perhaps for most people, how to choose the best audio equipment is a problem.

Lixin professional pipe joints to introduce several points in some power amplifier selection tips. Determination of the same benchmark power amplifier power is the most important parameter in sound systems, said the load carrying capacity of sound system. This is also our at the time of purchase should first pay attention to place. But if each manufacturer are used different determination of reference to identify theproduct performance, the lack of sufficient knowledge is often difficult to make an objective comparison. So is the amplifier, in view of power amplifier identificationshould pay attention to the following two points:

First, the battery voltage. Automotive battery voltage is constantly changing, the two kinds of common identity: 14.4V/100W, 12V/100W two kinds of power amplifier is acompletely different instructions. Because the voltage in automobile driving process is basically in about 12V, so in the 12V voltage state of the measured power value iscloser to the real situation to. And with the constant voltage 12V as a reference markpower amplifier can reach to obtain more power in the reach above 12V.

Second, harmonic distortion rate of THD. In the continuous output power comparisonamplifier, need to be in the same (or is close to the THD value of). Different values of THD to test out the sound quality difference is very obvious, sometimes its maximumpower logo is very high, but probably it's distortion and noise are also very high. So incheck the maximum power at the same time should also pay attention to theidentification of the THD value.

Lixin professional pipe joint representation in determining the same benchmark, we can compare the amplifier power. Usually, in the purchase of sound system generallyfollows the principle of the large power output. The power amplifier output power is more big, show their ability to drive a speaker more strong. Indicates the power amplifier power should be greater than the speaker, if you choose to use the power ofsmall, easy to burn out in the long-term use of large power output, but also lead topoor quality, appearance, such as distortion fault.

Factors of high-quality power amplifier should have

Of course, only by high power text is not able to better understand the quality of power amplifier. The quality of the power amplifier must be able to quickly response the peak of music signals, at the same time corresponding to a strong bass, and inlow distortion / can provide stable output low noise state. To meet these requirements,Lixin professional pipe joint said must have the following:

First of all, is the excellent performance of the power supply. This is about the keypower amplifier sound quality. The power supply part and the amplifying sectionshould be the separation of design, which can reduce the noise. Using a large step-up transformer to improve the current supply stability, and a large capacitor, can reactmore quickly, the supply current amplification required.

Secondly, the built-in parameter equalizer. Car sound is very different from home audio speakers, the installation position is very limited, the voice of the regulation is very important. In addition, since sound headrest and window shade sound effectsand installation angle of the subwoofer caused confusion, will car audio system sound.This is the role of parametric equalizer, which can compensate the peak and trough ofthe acoustic wave caused by reasons, regulation of smooth sound field.
