    济南btc365http://www.sdcarmusic.com/系统的时候,做好接地工作,这也是一个很重要的问题,而且理论知识是相当重要的,接地,电子技术中,既简单,又复杂,而且还必不可少。
     

    1、济南btc365用细砂纸将车体接地点处的油漆去除干净,将接地线固定紧。保护接地是为防止电源极性接反造成设备损坏而设置的保护装置,简单的方法是在电源的输入端对地加反向二极管,币投网站器材电路中尤为常见。
    Jinan modified car stereo body with fine sandpaper will take place at the removal of paint and clean the ground wire tight. Protective earthing is power protection devices to prevent reverse polarity damage to the equipment and set up, the simplest way is at the input of the power supply to ground plus reverse diode, car audio equipment circuit is particularly common.

    2、济南btc365主机和功放应该分别接地。器材电源输入端都有稳压电路,同时也设有过压保护电路和过流保护电路,以及温度保护电路。当系统消耗电流很大时,蓄电池接地端一定要牢固。在电源和接地间用粗直径的线材布线,如绞股线。这样做能够加强连接,有效地抑制噪声并提高声音质量。
    Jinan host and modified car stereo amplifier should be separately grounded. Equipment power input has a voltage regulator circuit, but also with overvoltage protection circuit and overcurrent protection circuit, and temperature protection circuitry. Current consumption when the system is large, the battery ground terminal must firmly. Between the power and ground wire to wire large diameter, such as the twisted strands. This connection can be strengthened to effectively suppress noise and improve the sound quality.

    3、济南btc365http://www.sdcarmusic.com/时不要靠近行车电脑布线。在所有接地中,屏蔽地最复杂,因为屏蔽本身既可防外界干扰,又可能通过它对外界构成干扰,而在设备内各元器件之间也须防电磁干扰,如大家熟知的中周外壳、电子管屏蔽罩就是例子。信号线屏蔽接地十分重要。请记住,主机接地点靠近行车电脑的接地点或固定点时,会产生行车电脑噪声,在汽车内所布的线材和音频线都要加上汽车专用护套套管。
    Jinan car stereos do not close when the trip computer wiring modification. In all grounded, the shield to the most complex, because both anti-shielding itself from outside interference, they may interfere with the outside world through it, and between the various components within the device also beware of electromagnetic interference, such as well-known in the week housing , tube shield is an example. Signal line shield grounding is very important. Remember, the host ground near the ground or the trip computer fixed point, trip computer generated noise in the car the cloth wire

    and audio cables should be coupled with automotive-specific jacket sleeve.
