我觉得已经用不着争论什么了……
GR2的说明书:
 
The NR button turns the noise reduction on (button “pushed in”) or off (button “out”). The Threshold control sets a level; signals above this level will pass through the gate (the Gate LED is off). If the signal dips below the threshold, then the gate closes (the Gate LED glows red). This is helpful if your pickups are picking up any kind of low-level hum or buzz; set the gate Threshold just above this noise, and when you aren’t playing, the gate will not let the hum or buzz through. As soon as you start playing and the signal exceeds the threshold, the gate will open; hopefully the signal will be loud enough to “mask” the buzz.
The Gate’s Learn function automatically sets an optimum threshold. Without playing your guitar, click on Learn. GUITAR  RIG  2 analyzes your signal, and sets the threshold just above any residual noise. Now when you play, the Gate should open
按下NR开关可以控制降噪的开和关,Threshold设定一个位置,在这个位置之上的声音将
通过这个“GATE”,当信号低于threshold,NR会关门(GATE灯亮了),当你的琴发出
HUM或者BUZZ的时候,将这个threshold设定在刚好超过噪音的电平值上,这样在你不演奏的时候,
GATE会关,它将不让任何噪音通过,当你演奏时,门会发开,足够大的吉他本身的信号会因为蒙蔽效应遮盖住噪音
已经说的很清楚了,这是一个GATE……
