SubBass
SubBass overview
SubBass generates frequencies below those of the original signal, resulting in articial bass
content. The simplest use for SubBass is as an octave divider, similar to octaver eect pedals for
electric bass guitars. Whereas such pedals can only process a monophonic input sound source of
clearly dened pitch, SubBass can be used with complex summed signals as well.
SubBass creates two bass signals, derived from two separate portions of the incoming signal.
These are dened with the High and Low parameters. See SubBass parameters on page 264.
WARNING: Using SubBass can produce extremely loud output signals. Choose moderate
monitoring levels, and only use loudspeakers that are actually capable of reproducing the very
low frequencies produced. Never try to force a loudspeaker to output these frequency bands
with an EQ.
SubBass parameters
SubBass oers the following parameters.
SubBass parameters
•
High Ratio knob and eld: Rotate to adjust the ratio between the generated signal and the
upper frequency band of the original signal.
•
High Center knob and eld: Rotate to set the center frequency of the upper frequency band.
•
High Bandwidth knob and eld: Rotate to set the width of the upper frequency band.
•
Graphic display: Shows the selected upper and lower frequency bands.
•
Freq. Mix slider and eld: Drag to adjust the mix ratio between the upper and lower
frequency bands.
•
Low Ratio knob and eld: Rotate to adjust the ratio between the generated signal and the
lower frequency band of the original signal.
