6.5 Compressor Mode (Dynamic Fat Channel) 压缩器模式 （动态Fat Channel）
6.5.1 Standard Compressor 标准压缩器
Dynamic Fat Channel Controls 动态Fat Channel Controls 控制
Pressing the Comp button in the Fat Channel gives you access to the
Compressor parameters for the selected channel or mix. A compressor is a
dynamics processor that reduces the dynamic range of a signal by attenuating it
by a set ratio when it exceeds a defined threshold.
在Fat Channel中按 Comp 键，可以访问所选通道或混音的压缩器参数。压
缩器是一个动态处理器，当信号超过一个定义的阈值时，它通过一个设定
的比例衰减，减少信号的动态范围。
StudioLive Series III mixers ship with three compressor models from which to
choose and the Fat Channel behaves differently, depending on which model is
loaded. The eight Scribble strips in the Fat Channel show pertinent data about the
current settings of these controls. The controls differ, based on the model of
compressor you select.
StudioLive III系列调音台有三种型号的压缩器可供选择，Fat Channel的表
现也不同，取决于加载的是哪种型号。Fat Channel中的八个Scribble strips
条，显示关于这些控制的当前设置的相关数据。根据你选择的压缩型号，
这些控制也有所不同。
For more information on available Fat Channel plug-in models, seeSection 6.8.4.

The Standard Compressor is selected on every channel by default.
默认情况下，每个通道都选择标准压缩器。

1. Threshold. Sets the level above which the compressor begins to attenuate
the signal.
设置压缩器开始衰减信号的电平。
2. Ratio. Sets the relationship between the amount a signal goes above the
threshold, and the amount it is attenuated. At a 1-to- 1 ratio (often written as 1:1),
no compression occurs. At a 4:1 ratio, a signal that passes the threshold by 8 dB
is attenuated to within 2 dB of the threshold (dividing by four). The higher the
ratio you choose, the more pronounced the compressor effect becomes.
设定信号超过阈值的量和被衰减量之间的关系。在1比1的比例下（通常写
成1：1），不发生压缩。在4:1的比例下，一个通过阈值8dB的信号，衰减
到阈值的2dB以内（除以4）。你选择的比率越高，压缩器的效果就越明显
。
3. Attack. Sets the time it takes for the compressor to begin attenuating a signal,
once it passes the threshold. Press the button below to toggle Auto mode
on or off. When Auto mode is active, the Attack and Release controls become
inoperative, and a preprogrammed attack and release curve is used. In this
mode, the attack is set to 10 ms, and the release is set to 150 ms. All other
compressor parameters can still be adjusted manually.
设定信号通过阈值后，压缩器开始衰减。按下面的按钮来切换自动模式
的开或关。激活自动模式时，Attack和Release控制变得不可用，要使用预
先编程的Attack和Release曲线。在这种模式下，Attack被设定为10ms，
Release设定为150ms。其他所有的压缩器参数仍然可以手动调整。
