5. 故障检测（接上一页）
CONDITION: No sound but remains power active.
POSSIBLE REASON:
• The amplifier has just turned on and is still in the 4-second
turn-on delay.
• The amplifier is in “fault” mode. A Fault status can be triggered
when one of the amplifier’s protection circuits is activated. First
disconnect your speakers from the affected channels(s) one by
one to determine if one of the loads is shorted. If the indicators
return to normal status, then try a different speaker or cable to
determine where the short is occurring. If no short can be found,
turn off the amp and allow the amp to cool. If indicators do not
return to normal after restarting your amp, check the breaker or
return amp to Crown or an authorized Crown Service Center for
servicing..
状态：电源接通但无声音。
可能的原因：
• 放大器刚刚开启，仍在4 秒开启延迟时间内。
• 放大器处于“故障”模式。当其中一个放大器的保
护电路被激活，将触发一个故障状态。首先将扬声
器从受影响的通道上逐一断开，确定负载是否被短
路。如果指示器返回到正常状态，那么试用不同扬
声器或者电缆，确定发生短路的地方。如果没有发
现短路，关闭放大器，让放大器冷却。如果指示器
在重启放大器后没有返回到正常状态，检查断路器
或者将放大器退回给Crown 或者经授权的Crown 维
修中心进行维修。

FAULT
CONDITION: Distorted sound.
POSSIBLE REASON:
• Input signal level is too high. Turn down your amplifier Level
controls. NOTE: Your amplifier should never be operated at a
level which caused the Clip LEDs to illuminate constantly.
状态：声音失真。
可能的原因：
• 输入信号电平过高。调小您的处理器音量。注意：
禁止放大器运行在可使削波发光二极管常亮的电
平上。
