1.6 Equalizer filter
There are three parameters programmable in the equalizer filter:
1.6.1 Attenuation
Figure 7 shows the boost and cut response as a function of frequency at a center frequency of 1kHz.

1.6.2 Center Frequency
This parameter is programmable in the filter stage 1(62/100Hz), 6(4/6.34kHz) and 7(15/16kHz) only.
Figure 8 shows the center frequencies 62, 156, 396, 1000, 2510, 6340 and 15000Hz of the 7 equalizer
filters.
