一、 噪音的检查方法:
Check method, noise:
a. 先着发动机,把大灯,空调打开,将音响系统开到可以聆听的位置;
The first A. engine, the headlight, open air conditioning, the sound system to can listen to the position;
b. 将发动机的转速稳定在3000转左右,不断地更换CD曲目,并细心聆听高音部分,听听是否有噪音(即V.V.的啸叫声)。如果没有噪音,说明该系统的设计、布局合理。
B. the engine speed to stabilize at around 3000 rpm, constantly changing CD tracks, and listened carefully to the treble part, see if there are any noise (i.e. V.V. Whistler). If there is no noise, that the system design, reasonable layout.
二、噪音的跟踪与排除:
Two, tracking and elimination of noise:
把所有的功放讯号输入(即RCA)解除,然后按噪音的检查方法检查,试听是否有噪音。
All the PA signal input (RCA) release, then click the check method of check whether there is noise, noise.
A、 噪音的跟踪方法:把功放的输出解除:拿个新的喇叭,直接接在功放上听,是否有噪音。
A tracking method and noise: the power amplifier output termination: a new speaker, directly connected to the power amplifier to listen, if there are noises.
有噪音需检查的项目有:
There is a need to check the project noise:
1、 检查功放的接地点是否正确,如不正确需重新找地线(注:两台以上楞放的接地点必须在同一个点上);
Ground point 1, check the amplifier is correct, if not correct to find ground (Note: more than two Leng ground must be put in the same spot);
2、 检查功放增益键的电位器接触是否良好;
2, check the amplifier gain potentiometer contact bond is good;
3、 检查功放的外壳是否有接地现象。
3, check whether the power amplifier shell grounding phenomenon.
无噪音需检查以下项目:
No noise need to check the following items:
1、 喇叭线的布置是否有搠近本车主电源供应线路;

3、讯号线的莲花端子与功放的莲花端子是否匹配。
Lotus lotus terminal terminal 3, signal line and power amplifier matching.
没有噪音须检查的项目:
No noise check project:
1、 CD机的供电线路是否良好;(建议:CD机的代电线路必须重新找,不能用原车的线路)
The power supply line 1, the CD is good; (suggestion: CD generation electric circuit must be to find, can not use the original car lines)
2、 CD机的输出端子与讯号线的端子配合是否良好;
Terminal 2, CD output terminal and the signal line is good with;
3、 检查CD机的电压与功放的电压是否相同;
The voltage and the power amplifier 3, check whether the same cd;
4、 检查发电机是否有交流输出。
4, check whether the AC output generator.
