CONDITION: No power to the amplifier.
POSSIBLE REASON:
• The amplifier’s Power switch is off.
• The amplifier is not plugged into the power receptacle.
• The amplifier’s high-voltage power supply circuit breaker has
tripped.
• Verify that the AC mains voltage is correct, then press the Circuit
Breaker button on the back panel.
状态：功率放大器没有电源供给。
可能的原因：
• 放大器电源开关关闭。
• 没有将放大器插入电源插座。
• 放大器的高压电源断路器跳闸。
• 检验交流电源电压是否正确，然后按下后面板上的
断路器按钮。

FAULT
CONDITION: No sound but remains power active.
POSSIBLE REASON:
• No input signal or the input signal level is very low, and 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：
• 无输入信号或输入信号电平太低的情况下，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。
