Effect parameters
Amplier
Pa5X includes accurate guitar and bass amplier and cabinet modeling. Some of
the effects combine an amplier and a cabinet model.
Modelling ampliers
Pa5X comes with a wide selection of the best amps, that offer the widest pos-
sible array of great tones. The operating mode of the preamp and power amp, the
response of the tone controls, and their placement within the circuit will change
depending on the type of amp you select, precisely replicating the exact gain and
tonal character of the original amp. The all-important power amp stage (class A or
AB) and negative-feedback circuit (or lack thereof) are also carefully simulated.
The volume controls
Two main controls affect the volume (or gain) and at the same time the tone of the
amp: Drive or Drive Gain (controlling the preamp gain and the amount of preamp
distortion) and Volume, Output or Out Level (controlling the preamp output lev-
el). Each control has its own specic job, and the sound of a particular amp model
can vary over a very wide range just depending on the settings of these controls.
In addition, the
Trim or Cabinet Trim control (a power attenuator) is placed be-
tween the output of your amp and the input of your speaker cabinet. At the end of
the signal path, the Wet/Dry parameter in the FX Edit page, and the Master knob
in the Mixer/FX > MFX Send page, control the level of the nal mix and allows you
to balance all your presets to each other.
We have made the relationship between preamp and power amp work in the same
way as in the original amps. Therefore, to obtain truly authentic tones, please use
the Pre/Drive Gain parameter to control the preamp distortion, and the Volume
parameter to control the distinctive distortion and warmth of the power amp
stage.
Be advised that setting the Drive Gain too high will result in heavy distortion, and
is not recommended.
