    當前位置:合理接地音響設備的外殼

    合理接地音響設備的外殼一般與設備的電源變壓器屏蔽連在一起,這臺設備外殼也有一個“地”,這個“地”與其他兩個“地”也有所不同。當大地的“地”比較干擾時,設備外殼的“地”與之相接可以降低交流聲干擾,反之則不要相連。
    1, the enclosure of reasonable grounding devices is usually connected with the shielding of the power transformers of the equipment. The shell of the device also has a "land", which is different from the other two "lands". When the earth's "ground" is disturbed, the "ground" of the equipment shell can reduce the interference of the AC sound, and vice versa.
    2、弱信號設備電源與強信號設備電源分組連接弱信號音源設備如CD、卡座、效果器、調音臺、壓縮限幅器和均衡器等同一組電源連接,強信號功率放大器與另一組電源連接,可以避免傳導方式的電源交流噪聲干擾。
    The power block device 2, weak signal and strong signal power equipment connected to weak signal source equipment such as CD, cassette, effects, mixer, compression limiter and a set of equivalent equalizer power connection, strong signal power amplifier is connected with a power supply and power supply can avoid the AC noise conduction mode.
