The DSP Functions
Bass Tone Control (PARA BASS)
This is a two-stage function, with control-input pages for frequency and amplitude. These pages
are the same as those for frequency and amplitude in PARA EQ. On the frequency control-input
page, you'll set the cutoff frequency. For notes above this frequency, the amplitude setting has a
diminished effect. On the amplitude control-input page, you'll set the amount of cut or boost
that's applied to notes below the cutoff frequency. There's a gradual increase in the bass
response for each successively lower note. The location of the cutoff frequency will change
somewhat as you change the amplitude settings, although the value for the Adjust parameter on
the frequency control-input page will not reflect the change.
