Noise Gate (Cyan)
In addition to the noise gate in the Input Section, there are two additional noise gates available as effects, developed
specifically with the hi-gain player in mind.
Whereas the noise gate in the Input Section is designed to preserve the guitar's dynamics exactly, the Noise-Gate
effects behave like classic downward expanders. Downward expanders attenuate a signal once it has fallen below a
certain threshold and are often used to tighten complex metal-riffing. This is because a palm mute will still retain all
of its "chunk", but will also become more percussive, thereby preventing the dreaded "mud". The two noise-gate
effects feature different expansion ratios, chosen for their musicality.
Noise Gate 2:1
This noise gate is a soft expander, with an expansion ratio of 2:1. If the level of the input signal lies below the
threshold it will be attenuated by a factor of 2. In other words, each dB below the threshold leads to 2dB attenuation
of the signal.

Noise Gate 4:1

This noise gate is a more aggressive expander, with an expansion ratio of 4:1. If the level of the input signal lies
below the threshold it will be attenuated by a factor of 4. In other words, each dB below threshold leads to 4dB
attenuation of the signal.
As with the Input Noise Gate, there are no attack or release controls, as we have selected the shortest possible
times without introducing any signal degradation. The attack time is 0.05 ms (that's 50 microseconds, or one twenty-
thousandth of a second), while the decay time is 50 ms. You can use the Noise Gate effects in combination with the
noise gate in the Input Section to benefit from the different noise gate characters.
