bad. Tube bias and preamp gain are independent parameters. For low preamp gain, it may be
desirable to use low tube bias values, because this more closely imitates the operation of a real
amplifier.
PREAMP EQ TRIM Range: -24 to +00 dB
Controls the input level to the pre-amp EQ to eliminate the possibility of clipping boosted
signals.
HIGH FC Range: 4 to 1000 Hz
Filters out the low frequencies before the preamp. The higher the value, the less low frequencies
pass through.
MID FC Range: 0000 to 9999 Hz
Determines the center-frequency of the parametric filter before the preamp. Higher values have a
brighter sound.
Q Range: 01 to 18
Determines the width of the resonant peak at the parametric filter center-frequency. 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
Adjusts the amount of boost or cut applied to the parametric filter in front of the preamp.
GATE - OFF Range: -96 to +00 dB
Sets the lower threshold level at which the noise gate shuts off the audio.
ON Range: -96 to +00 dB
Sets the upper threshold level at which the noise gate passes the audio. The higher second
threshold prevents false “turn ons.”
RELEASE Range: 1 msec to 10.0 sec
Sets the amount of time after the signal has elapsed for the noise gate to shut down. For a longer
sustain, set this parameter higher.
HIGH FC Range: 4 to 1000 Hz
Filters out the low frequencies of the main amp prior to the speaker. The higher the value, the
less low frequencies pass through.
LOW FC Range: 2.0 to 15.0 KHz
Filters out the high frequencies of the speaker. The lower the value, the less high frequencies
pass through. This speaker filter is less selective than the speaker cabinet emulation algorithms.
MAIN EQ MID-1 FC Range: 0000 to 9999 Hz
Determines the filter center-frequency of the 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 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
Adjusts the amount of boost or cut applied to the main amp parametric.
