2.5 Alternative: Choosing Phoenix Connectors as Input Connectors
Besides connecting the XLC amplifiers to the CXM2000 through HD-15 connector, you can also connect to other input
devices through the phoenix connectors on its rear panel. Crown recommends using pre-built or professionally wired
balanced line (two-conductor plus shield), 22-24 gauge cables and connectors (see Figure 2.7). Unbalanced lines may be
used, but may result in hum or RF noise over long cable runs.
NOTE: Custom wiring should only be performed by qualified personnel.
2.6 Choosing Output Wiring and Connectors
Crown recommends using pre-built or professionally wired, high-quality, two-conductor, heavy gauge speaker wire and
spade lug connectors or bare wire for your output connectors (Figure 2.8). To prevent the possibility of short-circuits, wrap
or otherwise insulate exposed loudspeaker cable connectors.
Non-Touch cover provides protection of electric shock from the output terminals. Remove it to connect the cables to the
output terminals and reinstall it when finish. To reinstall it, insert tab A into the slot right beside the output terminals (see
figure 2.9). Put the screw through tab B and screw it into the hole left beside the output terminals (see figure 2.9).
Below are the suggested guidelines to select the appropriate size of wire based on the distance from amplifier to speaker.
CAUTION: Never use shielded cable for output wiring.
NOTE: Custom wiring should only be performed by qualified personnel. Class 2 output wiring is required.
2.5 可选：选择凤凰头作为输入接口
除用HD-15接口连接XLC功放至CXM2000外，还可以选择后面板的凤凰头接口连接其他输入设
备。Crown建议您采用已有的或专业的平衡线（双导线带屏蔽），22-24线规的电缆和接口连接
凤凰插头（见图2.7）。您也可以使用非平衡线，但是，如果使用的电缆较长，会产生噪音或射
频干扰。
注意：必须由专业人员进行接线操作。
2.6 选择输出连接线和接口
在连接输出至扬声器时，Crown建议您采用已有或专业的，高质量的，双绞线的，大规格扬声器
线材及铲型接线片端口，或裸线（见图2.8）。为了防止短路，您需要包住或使用其他方法绝缘
外露的扬声器电缆接头。
防触摸保护壳用于对输出接口提供防电击保护。接线前需卸下保护壳，再连接线缆到输出接口；
在接线完成后，需装回保护壳。安装防触摸保护壳时，将页片A插入输出接口右侧的插槽内（见
图2.9），将螺丝穿过页片B，拧紧螺丝将其固定在输出接口右侧的小孔内（见图2.9）。
建议使用下表的指南，根据扩音器与喇叭的距离选择合适的音箱。
警告：不要使用屏蔽电缆作为输出连接线！
注：定制接线只能由合格的人员执行。要求使用第 2 类输出接线。
