玩三相電一相供音響一相供其他,這只是普通玩法,好玩又不想改機內部供電,可以找一隻大的隔離牛,初級接38 ...
There was an article from "Lui Ming" long time ago in HiFi magazine. Please see if you can find the original.
According to my memory, he mentioned all 3 phases are used separately. E.g. Left power amp use 1st phase, right power amp use 2nd phase, the preamp and source use the 3rd phase. The end result is roughly 3 phase use the balanced power if possible. The main essence is to allow them to have minimum interference to each other. Theory is a bit like back EMF; even you don't expect it to have any effect, the interference may cause some noise in each other.
If my memory is not right, please correct and forgive my aging memory. |
