Filter [FLT]
5.11
The stereo
Filter
block can be used for simple or spectacular sound shaping. It allows a variety of different effects
with real-time control of useful parameters. It can also be used as a “boost” by setting the
TYPE
to NULL or as a
treble (or mid) booster with greater programmability than the ones in the
DRIVE
block. The Filter block is equipped
with individual left and right pan controls. These allow you to adjust the placement of the left and right output
signals in the stereo field. You can use these controls to turn a stereo signal into two mono outputs (set both to
0.0) or to reduce the stereo separation, or you can use them as general stereo manipulation tools.
The filter is stereo-in/stereo-out. Each Axe-Fx II preset can use four fully independent
Filter
blocks.
Parameters
TYPE
– Selects between Null, Lowpass, Bandpass, Highpass, Low Shelf, High Shelf, Low Shelf 2 (passive type),
High Shelf 2 (passive type), Peaking, Peaking 2 (Variable Q type), Notch, or Tilt EQ. The NULL type has no effect
on frequency response but allows gain, phase, pan and other adjustments to be made. Note: Low and High
Shelf “2” filters recreate the quirly analog shelving filters found on classic mixing consoles. These exhibit
“overshoot” which gives them a certain musical quality. Set the Q between 0.5 and 0.707 to recreate those
classic sounds or experiment with the Q for different effects.
FREQ
– Sets the center frequency of the filter.
ORDER
– Selects different filter slopes. 2nd = 12 dB/ octave, 4th = 24 dB/ octave
Q
– Sets the “Q” of the filter. Higher values give sharper responses.
GAIN
– Sets the gain at the center frequency for the shelving and peaking filter types.
LOWCUT, HICUT
– These first-order filters provide additional tone-shaping capabilities.
LEVEL
– Sets the output volume level of the block.
BAL
– Sets the output balance of the block.
PAN L, PAN R
– These controls allow you to adjust the placement of the left and right output signals for
stereo width adjustment or stereo-to-mono conversion.
BYP
– Sets the bypass mode of the block. See
