关于Input 模块上的Noise Reduction: 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
单块上的Noise Reduction: Noise Reduction CComponent affects the signal similarly to a noise gate, but has a less abrupt action because it filters out noise below a certain threshold rather than relying solely on amplitude. It is very simple to adjust.
单块的噪音门:
A noise gate helps remove noise and hiss, but can also be used as a special effect. Although there is a simple gate built into the Input module, the Noise Gate CComponent is more sophisticated and offers more parameters.
To understand the principle of operation, suppose your guitar is picking up an electrical buzz. As long as you’re playing, the signal will generally be higher than the buzz and “mask” it. However, when the audio goes away, the noise is no longer masked and can be audible.
A noise gate does the equivalent of turning down the volume when there’s only noise present, then turning the volume back up when you’re playing. Its Threshold control sets the “dividing line” between what’s considered noise and what is considered signal. Setting the threshold just above the noise level insures that the noise will be muted when no signal is present.
Guitar pickups are very susceptible to hum, light dimmer “hash,” and the interference generated by computers and monitors. LCCD monitors create less interference than CCRT types, and humbuckers are less likely to pick up interference than single coil pickups. Piezo pickups, like those used in the Line 6 Variax, do not pick up this interference.
As you play with GUITAR RIG 2, always position your guitar so it picks up the least amount of interference. GUITAR RIG 2’s Noise Reduction can help get rid of some interference, but it is not a substitute for orienting your guitar away from sources of interference.
3.4 Using Noise Gate
When using high gain and naturally noisy guitar effects, it is often good to use a noise gate to minimize the amount of unnecessary noise passing through the guitar rig (figure 3.6).
THRESH. (Threshold): Sets the threshold level for the signal. When the signal drops below the set threshold level, the noise gate silences the signal. Usually keep the Threshold level at the lowest possible value (fully counterclockwise) and set it higher only when you need the gate to work.
REL. (Release): This sets the gate release time. Higher values will result in a gate that takes a longer amount of time to close again when the input signal disappear.
当使用High Gain 失真时或使用自然而然会让吉他戴上噪音的效果预设,使用噪音门来使通过guitar rig的不必要的噪音减少是常常非常有效的。
SOME STOMP TIPS:
The stomps are available only through the Stomp PedalBoard. The minimal PedalBoard offers 2 Stomp spaces. It often sounds good to start with the Gate or Gate/Comp Stomp to eliminate pickup buzz, signal noise, etc. This is especially useful when using distortion setups or when going into a driven or high gain amp.
通常最好的做法是把Gate或者Gate/Comp 放在第一个,可以去除拾音器嗡嗡声,信号噪音,等等。 尤其是当使用失真设置或者信号进入一个过载或者High Gain 的放大器时。(amp,机头)
Input adjustment
Different guitar pickups supply different output levels. The front panel Trim knob can be used to scale the guitar’s input level so that it feeds the ideal level into the recording device for optimal Signal to Noise Ratio without clipping. Single coil pickups usually enjoy a bit of a gain boost while humbucker and active pickups sometimes require a slight pad to prevent them from clipping.
Module name = ShutUp Sch‐1b, Noise gate
Description = A noise gate is a simple way to get rid of noise in the signal. The traditional way
such an effect works is lowering the volume of the signal when the signal itself becomes very
weak (as it is mostly then you can hear the noise). The ShutUp Sch‐1b is different in two ways:
This noise gate is not “either closed or opened”, but is sliding smoothly in between the two. Sec‐
ondly, Sch‐1b does not affect the actual “volume” but is continuously changing the filter param‐
eters of an intelligent filter circuit. You may very well notice that the noise gate is half‐closed
when playing softly. Compared to traditional noise gates this has the impression of being per‐
fectly responsive. The noise gate has 4 separate bands, where as the fourth has an adjustable
frequency.
