    如題...有點好奇相位接反會有哪些情形發生?!

    最近把琴拆開來看 發現接法跟網站上提供的接法不太一樣...不知是否相位接反了

    拾音器我倒是不知道
    不過我有把唱歌的交流阻抗相同的麥克風音頭相位接反過
    人耳聽不出來有差別
    不過兩支正負相位不同的麥克風靠近使用會有沒聲音的現象
    (似乎是正負抵銷的樣子)
    拿遠一點就很正常了

    Dear Monkey,

    Please let us know exactly what happened if you can.

    For your post, trust that you are referring to "out of phase". For example, a strat with real single coil pus, normally, single coil pu have two output wires, one was hot, the other was ground. IF both single coil was of the same magnetic polarity, we run the hot wire of middle pu to the selector, ground the ground wire, then run the ground wire of the bridge pu to selector, then ground the hot. By this, at the position 4, you will have a out-of-phase sound, which was a clean, trebly hollow sounds. But, on position 3 & 5, you still have normal single coil sound. If you experience this problem and don't liked it, simply exchange the wire of bridge pu (i.e, wire the hot to selector, ground the ground wire).

    Hope it will be clear for you, if your problem was with humbucker pu, please e-mail to me at pwanhku@yahoo.com.hk

    Best regards,
    PATRICK
