线缆连接  – 70V  工作模式 

音箱线 

用于70V系统的音箱配线非常简单。  在每个扬声器位置布置一根两芯多股线,在每

个扬声器位置预留一段环路  (60至90厘米通常绰绰有余,这取决于扬声器及其安装方
式)。您可以预留额外的环路以便将来系统扩展或在需要时更改扬声器位置。 

 

注意:

这与典型的用于传统音频安装的低阻抗布线方式非常不同,在传统音频安装

中,专用音箱线路需要从每只扬声器返回到功率放大器。70V线路所使用的导线少得多,
即使是较长距离的线路,也可以使用较大线规的导线  (更细的导线)。 

 
以下图表显示了低阻抗  (4Ω-8Ω)  和高阻抗  (70V)  系统不同导线长度之间的差异:

注意:与传统的立体声音频不同,70V系统通常使用单声道运行,因此扬声器只需一根
导线连接。如果您想使用多根导线来实现扬声器分区或其他用途,则每根导线需要独立
连接到自己的功率放大器或某一路功率放大器通道的端子  (当使用多通道放大器时)。 
1.   在每只扬声器位置,切断扬声器位置处的导线环路。 
2.   从电缆外皮的末端剥去1至2英寸  (2.5至5厘米)。然后再剥去每根导线上的½英寸 

(1.3厘米)  的绝缘层。 

3.  将多股线导体拧紧,以免铜丝与导体线束分离。
