SPEAKER OUTPUTS

这两个并联的1/4”单声道插孔(TS)用来连接扬声器机箱。同样，扬声器的最小匹

配阻抗为4欧姆。CABINET IMPEDANCE SWITCH(23)(音箱阻抗开关)的设置应与

连接的扬声器负载相匹配。

LINE OUT LEVEL

此控制钮设定由LINE OUT(26)(线路输出)插口发送的信号电平。可用于平衡由

LINE OUT(26)(线路输出)驱动的从属功放/扬声器至SPEAKER OUTPUTS(24)

(扬声器输出)驱动的音箱的电平。

LINE OUT

此1/4”单声道插孔(TS)提供一个前置功放信号，在保障放大器音质的同时驱动另

一台功放/扬声器系统。

FUSE

熔断器位于熔断器座的盖子中。此熔断器必须用相同类型和相同电流值的熔断器来

替换，以避免损坏放大器并使保修无效。如果放大器的熔断器反复烧断，应将放大

器拿到指定的服务中心进行维修。

警告：只有拔掉电源线后方可替换FUSE(熔断器)。

GROUND POLARITY 开关

此三位摇臂开关通常应设在中心(o)的位置。如果扬声器音箱有哼声或噪音，可以

将开关拨到“+”或“-”的位置，尽量降低哼声/噪音。如果改变电源极性不能纾

缓问题，请咨询指定的Peavey经销商，Peavey工厂，或合格的维修技师。

IEC (国际电工委员会)电源输入接口

此为标准的IEC(国际电工委员会)电源输入接口。在包装盒内包括有相应AC插头和

额定操作电压的AC电源线。该电源线应先和放大器相连后方可接到适当的AC电

源插座上。

美国国内AC电源线

本机配置的电源线为耐用的3芯线，带有接地脚的传统120伏AC插头。如果使用的

电源插座没有接地脚，则应使用相应的接地转换器，并将第三根导线正确接地。

千万不要折断任何设备上的接地脚。这是为了您的安全起见。
