Notes : (1) The gain values in the treble and bass data setting tables above are based on the assumption that the filter constants have
been set so that maximum and minimum gain are equal to the peak and bottom values listed in the frequency characteristics
drawings.
(2) All figures in this table are reference values. When using this IC, check this table carefully and perform the appropriate setting.
