The tone control is designed for a fluctuation of "15dB
(Typ.) when the frequency that you want to boost or cut
is a peak or valley of the frequency characteristics for the
filter. So be sure to design the filter while taking into con-
sideration its frequency characteristics.

When volume attenuation increases, tone control width
will change. Reference values are listed below, but be
aware that actual values vary for different products.
(Reference values)
At attenuation of 0dB, tone control width is "15.0dB.
At attenuation of *40dB, tone control width is "13.5dB.
