LED INDICATORS

LED 指示器可用于监视系统操作和确定一般问题。

电源:一个绿色 LED,在增益控制组的左端。

正常指示:交流电源开关打开:LED 闪亮。

如果没有显示:检查交流电源线和交流电源出口。确 认数据埠 1-2未将放大器置于 ‘备用’模式。

接线柱:红色,在增益控制的右边。

正常显示:闪亮,如果放大器超过全部动力驱动。失 真结果与 LED 的亮度对应。短暂闪烁造成的失真几乎

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。

异常显示:

-如果放大器正在使用时,闪亮明亮的红色,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,操作会在一分钟 内重新开始。允许风扇运转,确保放大器通风足够。

-短路或超载输出电路会造成过量接线柱闪烁和可能的 过热。

如果可以感觉到失真,而没有出现接线柱指示,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该范围的 上半段,以防止输入超载。

CH

信号:绿色,在每一个接线柱 LED 下。

正常显示:闪亮,输入信号超过 –35 dB。随着信号接 近最大功率, LED 会连续闪烁。

如果没有显示:检查增益设置;如有必要,增加增益 值。检查输入连接和信号的音频源。如果接线柱 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:如果信号 LED 闪亮,而没有信号输入,可

能是系统震动或其他故障。断开负载,大幅度降低增 益。如果信号 LED 保持为开,放大器可能需要进行维

修。

桥式和并行模式:桥式模式下,每个通道对都有一个黄色 LED,并行模式下则为橙色 LED。这些显示后面板开关的设 置 (参见第 5 页)。在立体声模式下,两个 LED 都应该是 关闭的。
