机架安装

按如下所示的步骤安装: 用四颗螺丝和垫圈将放大 器安装到设备机架导轨上。要在机架外使用放

大器,需在底部装上自粘性橡胶脚垫。

冷却

空气从机架流入放大器后面,从前面流出。 这可使机架冷却。放大器工作量增大时,风 扇自动加大转速。

不要挡住前面或后面的通风口!

CH

QSC 放大器中的气流:冷却风扇将冷空气 吸入放大器的后部。热风从放大器前盖流 出。

交流电源连接

连接交流电源到放大器后面的 IEC 插槽。注意:在连接交流电源前需关闭交流电源开关。要使用远程控制系统 或待机功能,必须打开交流电开关。

正确的交流线压在后面板的序列号标签上注明。连接错误的线压会损坏放大器或增加电击危险。
