The Speakon connector is designed specially for high-power speaker connec-
tions. It locks in place, prevents shock hazard, and assures the correct polarity.

The upper Speakon jack has both Channel 1 and Channel 2 outputs, so it is
especially useful for parallel, bi-amp, or bridged mono operation (see bridged
mono operating precautions on page 13). The other Speakon carries only Chan-
nel 2's output. See the illustrations at left.
For easier insertion, use the newer-style NL4FC Speakon connectors with

连接
输出端
（双声道型号）
Speakon™
双声道 DCA 放大器提供以下输出连接选择：两个 Neutrik NL4MD
Speakon 插孔和一个具有螺纹终端的屏蔽带。
Speakon 连接器专为高功率扬声器连接而设计。它锁定就位，可
防止电击危险，并确保电极正确。
上面的 Speakon 插孔同时具有声道 1 和声道 2 输出端，因此对
并行、双放大器或桥式单声模式操作特别有用（请参见第 13 页
上的桥式单声模式操作注意事项）。另一个 Speakon 提供声道 2
输出端。请参见左边的插图。
请使用新款的 NL4FC Speakon 连接器，该连接器拥有快速锁定的
指按栓，可以更方便地进行插接。
扬声器布线
更粗的电缆和更短的长度能使功率损耗和阻尼因数的降低最小。
不要使扬声器电缆靠近输入线缆。
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。电击危险！
