输入端

每一个声道都有一个已平衡的 XLR 和接线盒 输入。 输入已平衡、阻抗为 20k 欧姆或 非平衡的 10k 欧 姆。

对于低交流电源声和干扰,特别是使用很长的连线 时,建议采用平衡连接。非平衡连接适用于短电缆 的情况。信号的源阻抗应低于 600 欧姆。若数据端 口正用于给放大器提供输入信号,切勿将输入信号 接入 XLR 或接线盒连接器。

若需要非平衡连接,将信号线接入连接器的+极 , 并且把防护罩接入地线。在地线和-极间连接一跳 线。

平衡接线盒输入:将线剥去 ¼ 英寸 (6 厘米 ),连接到连接器上,如图 所示。拧紧螺丝。

非平衡接线盒输入:将电线剪至 ¼ 英寸,依所示插入插孔。中间的针 必须连接到屏蔽针上,如图所示。 拧紧螺丝。

平衡 XLR 输入:依所示连 接至插座。

直接低阻抗输出

直接低阻抗输出连接显示在机箱背部,输出终端的 右部。仔细注意极性标记,排列顺序方便进行桥式 连接。

立体和并行模式-依输出端右部机箱标签所示,将 每个扬声器负载接入放大器自身通道。对于立体声 或并行模式,模式设置开关 (第 5 页)必须设置。

桥模式-桥模式设置放大器驱动单一、高功率扬声 器负载。参见第 5 页设置桥式开关。依输出端子右 部标签所示连接负载。使用标为 BRIDGE MONO 的中 间两个输出端子。桥模式下最小阻抗为 4 欧姆。使 用立体声或并行模式通道驱动 2 欧姆负载。

桥模式注意事项:在桥模式下勿使用小于 4 欧姆的负载。使用桥接模式,最小阻抗是 4 欧姆。

输出端子安全警告!放大器电源打开时切勿 接触输出端子。进行所有连线之前先关闭放 大器电源。有触电的危险!

警告!有触电的危险!应使用 Class 2 配 线。

ISA 1350 警告:使用正确的扬声器配线。应 使用 Class 2 配线。对于单声道桥接模式, 应使用 CLASS 3 配线。

非平衡 XLR 输入: 依所示 连接至插座。中间的针必 须连接到屏蔽针上,如图 所示。

直接低阻抗输出:按照紧挨输出端子的标签所示连接扩 音器。注意单桥连接 (中间端子)和极性!
