MAGNAT QUANTUM 677, 675, 673 的BI-WIRING/双线分音和BI-AMPING/双路功放
推动
Bi-wiring/双线分音是指高频和低频分别由不同的线路分开传送。Bi-amping/双路功放推动
方式时,除 了需要第2条线路外,还需要额外使用第2个终端放大器。后者主要是为了能够进
一步提高音响效果。
Quantum音箱配有专门的接线端子,既可供传统运作方式使用,也可供双线分音和双路功
放推动运作方式使用。外部的4个螺栓接口是其识别标志。上方的两个接口接高音喇叭,下
方的接低音喇叭。正负接口在产品出厂前已经通过金属连接桥相互接通。如果是使用双线分
音和双路功放运作方式,必须去除连接桥切断连接。音箱的正确连接见图4a (传统式),图 4b
(Bi-wiring/双线分音)和图4c (Bi-amping/双路功放 推动)。

避免需要修机的几点建议
当音色调节器处于中间位置,即放大器线性运作时,所有MAGNAT-喇叭的音色都调在最佳
态。 如果音色 调节器调得过强,会有更多的电能传给低音和/或高音喇叭,这样在大音量
运 作 时,会损坏喇叭。
如果您的放大器的输出功率比喇叭上标注的容许负荷高出很多,这时将发出粗暴的声音,而
会损坏喇叭。但这种现象的出现实为偶然。
输出功率弱的放大器则在中等音量时就会对喇叭造成危险,因为它比大功率放大器更容易超
载。因超载导致的声音失真不但可以清楚地测量出来,而且还听得出来。这对您的喇叭非常
危险。
因此请您在调音量时,要注意观察声音是否失真。一旦出现声音失真,应该立刻调低音量。
喜欢欣赏大音量的人必须注意,放大器发出的输出功率应至少能为喇叭所承受。
总而言之...
放大器、调谐器和 CD –不只是抵挡产品 –都会产生听不见的高频颤动。如果高音喇叭在
到低音 量到中等音量时消失,应请专业人员来检查您的音响设备。
