Signal LEDs.
The Input Signal LEDs offer three signal threshold indications:

输入信号
LED
灯，共三种信号阈值指示：
• Green.

• Green.
当输入信号超过
-50dBFS
时，该灯将亮起绿色。
• Yellow.
Thelightwill illuminateyellowwith the input signalexceeds-2.0 dBFS
• Yellow.
当输入信号超过
-2.0dBFS
时，该灯将亮起黄色。
• Red (Clip).
The red Clip LED will illuminate when your input signal
reaches -0.5 dBFS. At this level, the signal will begin to overload the
analog-to-digital convertersand exhibit signs ofclipping.Use the gain
controls to keep the signal below this level. (
Note:
The once the
signal has exceeded the Clip Threshold, the LED will stay red for one
second)
• Red (Clip).
当你的输入信号达到
-0.5dBFS
时，红色的
“Clip”LED
灯
将亮起。在这个电平上，信号将开始超过模数转换器的负荷，
出现削波的迹象。使用增益控制，来保持信号低于这个电平。
(
注意：一旦信号超过了削波阈值，
LED
灯将保持红色一秒钟。）
48V:
The Quantum 2626 interfaces provide 48V phantom power in
two banks of four microphone preamps. When 48V is active, the
blue LED at the top of that channel’s meters willilluminate.

幻象电源。当
48V
电源被激活时，该通道仪表顶部的
蓝色
LED
灯会亮起。
Warning:
Phantom power is only required for condenser microphones
and can severely damage unbalanced dynamic mics, especially ribbon mics.
Therefore, switch phantom power off for all channels where it is not required.
警告：幻象电源只适用于电容式麦克风。而会严重损坏不
平衡的动态话筒，特别是带状话筒。因此，请关闭所有不
需要幻象电源的通道。
