1、将主机的附加功能全部恢复到出厂默认状态，高、中、低音全部置中，就是即不增加也不衰减，前后声场、左右平衡也一样。这样做的好处是即使每张碟的录音效果都不一样，我们都可以利用调整功能适当的增加一些高音和低音来补充。将功放的音量全部设置在最低的位置，滤波器设置在OFF，截止频率设置在最低，低音炮功放同样是这样处理。
Additional features will be fully restored to the factory default host state, high, middle and bass all set, and that is that is does not increase nor decay, front and rear sound field, left-right balance is the same. The advantage of this is that even sound effects are not the same for each dish, we can take advantage of an appropriate adjustment to add some treble and bass to supplement.The amplifier's volume all set at the lowest position, the filter is set at OFF, the cut-off frequency is set at a minimum, subwoofer amplifier is also handled this way.

2、开主机，播放一些高保真的人声碟或低音动态强劲一些的碟，将音量扭到过半或3/5的位置，这样更容易使低音和前声场的中低音衔合，更容易产生丰满的低音。
Open the host, play some high-fidelity vocal dynamic powerful bass dish or some discs, set the volume to half or 3/5 twist position, it is easier to make the bass and the bass sound field before the title together, more prone to plump bass.

3、接下来我们将主机的音量关小，放入一张人声碟或低频强劲一些的碟片，再将主机音量慢慢开大，直到比你正常听音稍大为止，这时你该仔细听是否清晰。
Next we will host the volume down, into a dish or low frequency strong vocals some discs, and then slowly turn up the volume of the host, until slightly larger than normal listening until you,then you should listen carefully is clear .

4、调整后声场，无论前声场是在什么状态，后声场都要设置在HP状态，截止频率扭到150HZ附近，这时，将主机音量扭大，在正常偏大的音量下，将功放推后声场的GAIN扭大，在前座位“感觉”到后声场有声音出就是正确的，听得到的话就代表声音过大了。
After adjusting the sound field, no matter the sound field in any state of the sound field to be set up in the HP state, the cutoff frequency twist to the nearby 150HZ, this time, the host volume twist large, normal is too large volume, the amplifier pushed back sound field the GAIN big twist, the former seat "feel" the sound field after a voice that is correct, then you hear the sound too large representative.

5、低音的调整是汽车音响的一个关键，调整得好将使声音发生天翻地覆的变化。感觉和前门喇叭一起发出，从前门传过来，低频量感不多不少。
Adjust the bass is a key car audio, adjust the sound turned upside down well make happen. Feeling and front door speaker issued together, pass over the front door, but not too much sense of low volume.
