TS-12 Musician’s Manual Section 7 — Effect Parameters
37
MAIN EQ MID-2 FC Range: 0000 to 9999 Hz
Determines the filter center-frequency of the second parametric in the main amp stage. Higher
values have a brighter sound.
Q Range: 01 to 18
Determines the width of the resonant peak of the second filter center.
LEVEL Range: -48 to +24 dB
Adjusts the amount of boost or cut applied to the second main amp parametric.
65 GUITAR AMP 3
GUITAR AMP 3 combines an inverse expander with a bright distortion for amp lead sounds.
The inverse expander may be thought of as a compressor that amplifies all signals below the
threshold. This algorithm is good for heavy metal and hard rock guitar solos. The FX-1 and FX-2
parameters can be routed into the effect with different Dry/Wet mixes.
PREAMP GAIN Range: -48 to +48 dB
Adjusts the amount of boost or cut applied to the EQ’d incoming signal. Lead sounds are
obtained using high gain.
MAIN LEVEL Range: 00 to 99
Controls the output level before the output EQ.
EXPANDER - RATIO Range: 1:1 to 40:1, infinity
Sets the amount of inverse expansion. Expansion occurs below the threshold. If this is set to 3:1
for example, it will expand the change in signals below the threshold by three times in an attempt
to make the signal amplitude approach the threshold level.
THRESH Range: -96 to +00 dB
Sets the inverse expander threshold level. Signals beneath this level will be expanded, while
signals that are above will be unaffected. As the input signal dies away below the threshold, the
expander will increase the gain of the signal.
PREAMP EQ TRIM Range: -24 to +00 dB
Controls the input level to the preamp EQ to eliminate the possibility of clipping boosted signals.
MID FC Range: 0000 to 9999 Hz
Determines the filter center-frequency of the parametric in the preamp stage. Higher values have
a brighter sound.
Q Range: 01 to 18
Determines the width of the resonant peak at the filter center. While the Filter center parameter
determines where (at what-frequency) this peak will occur, the Q setting controls the presence of
the peak.
LEVEL Range: -48 to +24 dB
This parameter adjusts the amount of boost or cut applied to the preamp parametric.
GATE - OFF Range: -96 to +00 dB
Sets the lower threshold level at which the noise gate shuts off the audio.
