LED 指示灯

LED 指示灯可用于监视系统运行和标识一般问题。

电源:绿色,在桥接 (BRDG) 和并行 (PAR) 指示灯上方。 正常指示:交流电源开:LED 点亮。

如果没有显示:检查交流电源线和交流插座。确认数据埠 1-2 未将放 大器置于 ‘待机’模式。

削波:红色,靠近通道编号标记。

正常指示:当放大器超出满功率驱动时会闪亮。失真结果与 LED 的亮 度对应。短暂闪烁对应的失真几乎感觉不到。

-在静音状态下,LED 完全闪亮。当处于正常的 “开 - 关”静音下会 发生此种情况。

异常显示:

-如果放大器正在使用时发出明亮红光,说明是热静音或是短路输出。

-如果放大器过热,风扇会全速运转,运行会在一分钟内重新开始。让 风扇运转,确保放大器有足够的通风。

-短路或过载输出电路会造成过度的削波闪烁和可能过热。

如果可以感觉到失真,而没有出现削波指示,问题可能发生在放大器 之前或之后。检查是否有损坏的扩音器或超载信号源。放大器增益控 制应该在此范围的上半段以防输入过载。

信号, -20dB, -10dB:绿色,在各削波 LED 的下方。

正常指示:如果输入信号超出 -35dB,则信号指示灯亮,如果信号超

-20dB,则 -20dB 指示灯亮,如果信号超过 -10dB,则 -10dB 指示 灯亮。

如果没有指示:检查增益设置,如果需要可增大增益。检查输入端连 接和信号的音频源。如果削波 LED 闪亮只有很少或没有信号显示,检 查输出线是否短路。

异常显示:如果在没有信号时信号 (SIG)、-20dB-10dB LED 亮 起,可能是由系统波动或其它故障造成的。断开负载,大幅度降低增 益。如果 LED 仍然亮着,放大器可能需要进行维修。

桥接和并行模式:

桥接模式下,每个通道对都有一个黄色 LED,并行模式下则为橙色 LED。显示如何设置后面板切换器 (见设置模式切换器)。在立体声模 式下,两个 LED 都应该是关闭的。

双通道型号上的 LED 指示灯。

四通道型号上的 LED 指示灯。
