Gate Fast Button
The Fast control reduces the release time of the gate. It has no effect on the attack
time. When enabled, the gate will release quickly. On signals that slowly
decay and/or have a wide dynamic range, a smoother (less choppy) sound
may be obtained with Fast mode turned off.
Fast mode is engaged when the button indicator is bright red. The time values
are 50ms when engaged and 170ms when off.
Gate Threshold
Knob
Sets the threshold level for the gate. Any signals that exceed this level are
passed into the module. Signals below the threshold level are increasingly attenuated.
A Threshold of –96dB means the gate is always open. The range is
0dB to –96dB.
In typical use it’s best to set the gate threshold value to just above the noise
floor of the desired signal (so the noise doesn’t pass when you are not playing),
but below the desired signal input level (so the signal passes as you
play).
Boost Button
The Boost button (Figure 120 on page 325) increases the overall signal level
within Preflex by 20dB. It is completely independent of the Gate and Compressor
On/Off controls and will provide a signal boost even with the Gate
and Compressor are off.
Note: The Boost button is only available within Nigel and Preflex. The individual
Gate/Comp plug-in does not contain the Boost button because Boost only
affects the Amp within Preflex.
Compressor
Threshold Knob
Sets the threshold level for the compression. Any signals that exceed this level
are compressed. Signals below the level are unaffected. A Threshold of 0dB
yields no compression. The range is 0dB to –60dB.
As the Threshold control is increased and more compression occurs, output
level is typically reduced. However, the compressor provides an auto-makeup
gain function to automatically compensate for reduced levels. Adjust the Output
level control if more gain is desired.
Compressor
Ratio Knob
Determines the amount of gain reduction used by the compressor. For example,
a value of 2 (expressed as a 2:1 ratio) reduces the signal by half, with
an input signal of 20 dB being reduced to 10 dB. A value of 1 yields no compression.
Values beyond 10 yield a limiting effect. The range is 1 to 60.
