Figure 11. EQ band1, normal- and DC-mode @ boost = 15 dB, fCenter = 62 Hz

Note: The center frequency, Q, DC-mode and boost/cut can be set fully independently for each filter.

2.7 Subwoofer Application

There is one separate subwoofer output. A low-pass filter stage at this output allows the selection of three dif-

ferent frequencies: 80/120/160Hz. A high Pass Filter stage is present in the main path with selectable 90/135/

180/215Hz frequencies. Both filters, the low-pass as well as the high-pass filter can be disabled and have but-

terworth characteristics so that their cutoff frequencies are not equal but shifted by the factor 1.125 to get a flat

frequency response (see Figure 12).
