TDA7416
1.6.5 DC-mode of equalizer band 1 (62/100 Hz)
In this mode, the DC-gain 4dB when set to 15dB boost.
Figure 11. EQ band1, normal- and DC-mode @ boost = 15 dB, f
Note: The center frequency, Q, DC-mode and boost/cut can be set fully independently for each filter.
1.7 Subwoofer Application
Figure 12. Subwoofer Application with Lowpass @ 80/120/160Hz and HighPass @ 90/135/180Hz
Both filters, the lowpass- as well as the highpass-filter, have butterworth characteristic so that their cut-off
frequen-cies are not equal but shifted by the factor 1.125 to get a flat frequency response.
