回复 11# 白了头一夜间 的帖子
呵呵!幽默还难得糊涂,不说意见合不合但投机。我在功放的用户手册抄了这段,是说接地的,我也似懂非懂,
Your amplifier power cord is equipped with a standard three-prong grounding plug which, if used normally, will ground the chassis to the power line. While this procedure provides the maximum possible safety in use, it will, in many cases, cause your audio system to have a residual hum.
It is usually best to keep the preamplifier "earth grounded" and "float" the grounds of power amplifier and other equipment to eliminate ground loop hum.The audio interconnect cables then keep the power amplifiers at safe earth ground potential. If there is any question as to the safety of grounding procedures, be certain to seek competent help with the installation.
