6.4 Gate Mode (Dynamic Fat Channel)
门控模式（动态发声通道）
Pressing the Gate button in the Fat Channel gives you access to the Noise Gate
parameters for the selected channel or mix. A Gate is a dynamics processor that lets
you silence (or attenuate) signals that fall beneath a chosen signal level. This makes it
possible to reduce the presence of noise or other undesirable signals in the spaces
between the sounds you want.
在
Fat Channel
中按
Gate
键，你就可以访问所选通道或混音的噪声门参数。噪声
门是一个动态处理器，可以让你将低于选定信号电平的信号静音（或衰减）。
这样，在你想要的声音之间的空隙中，可以减少噪音或其他不良信号的存在。
The Noise Gate can be switched to function as an Expander. An Expander is another
type of dynamics processor, that works like a Compressor in reverse. Rather than
attenuating signals that pass a chosen threshold level, an expander boosts signals
that pass its threshold. This comes in handy when trying to restore punch and impact
to signals that have been overly compressed, or which are not naturally as dynamic
as desired.
噪声门可以被切换成扩展器的功能。扩展器是另一种类型的动态处理器，它的
工作原理类似于反向的压缩器。扩展器不是减弱通过选定阈值的信号，而是提
升通过其阈值的信号。当试图恢复被过度压缩的信号的冲击力时，或者当信号
的自然动态不理想时，这就很方便了。
Power User Tip: Inpractice, expanders and noise gates are used almost identically. The
main difference is that an expander is smoother and more gradual, so that it is easier to
set the attack and release times correctly. More information about Gates and Expanders

Inpractice
，扩展器和噪声门的使用几乎相同。主要的区别是，扩展器更平滑、
更渐进，更容易正确设置

1. Threshold. Sets the signal level that bisects the signals you wish to keep from
the signals you want to attenuate. Signals below this level are attenuated
according to the setting of the Range parameter. Signals above this level pass
through unaffected.
设置信号电平，将你希望保留的信号与想衰减的信
号一分为二。低于此电平的信号，根据范围参数的设置进行衰减。高
于此电平的信号，不受影响。
2. Range. Sets the amount of attenuation applied to a signal when its level falls
below the Threshold. Lower settings pull signal level down further, all the
way to -∞, if desired. Higher settings pull the signal down to a lesser extent,
de-emphasizing noise and other nuisance signals more subtly (without a“hard”
cut-off). Note: Range is disabled when the Expander is engaged.
当信号的电平
低于阈值时，设置应用于信号的衰减量。如果需要的话，较低的设置可以
进一步拉低信号电平，一直到
-
∞。较高设置将信号拉低到一个较小的程
度。更巧妙地强调噪音和其他干扰信号（没有一个
"hard"
的切断）。注意：
当扩展器投入使用时，范围被禁用。
