The Controls for Chrome Tone Amp
Pre
The Pre section provides low cut ltering to remove
unwanted DC and similiar noise from the signal path,
while also provided coloring to the track appropriate for
guitar and other applications.
The primary source of noise in most guitar signal paths is
DC and 60 Hz hum. These unwanted signals are automatically removed with the
low cut lter in the Pre section. The low cut frequency range extends down to
75 Hz, and a variety of Pre types are available to color the input signal (subtle
bass boosting, more gentle lter roll offs, vintage pre models).
A common use of products like Chrome Tone is to re-amp the already recorded
guitar track. Using the Pre ‘vintage’ modes, this affect can be achieved on a
directly recorded guitar track.
Noise Gate
The Chrome Tone Noise Gate is designed to
minimize the amount of noise heard at the output
of the Chrome Tone Amp plug-In. Large amounts
of gain common to most guitar ampliers raise the
noise oor of the input signal considerably. When
the performance from the guitar or other input
stops, this noise oor becomes very audible. The Gate section automatically
reduces input gain to zero when the input signal drops below the selected
threshold. The Attack, Hold, and Release controls allow the Gate to open and
close in a way that does not interfere with the actual performance.
The Noise Gate controls are:
• Threshold - the level at which the gate is engaged (closed). When the input
signal drops below the threshold, the gate closes and no more signal is
outputted.
• Attack - the rate at which the gate opens.
• Hold - the amount of time the gate remains open once signal level rises
above the Threshold.
• Release - the rate at which the gate closes.
