DC-Mode

The filter stage 1 (62/100Hz) has a programmable +4dB DC-gain when the boost is set at

+15dB (See Figure 13).

Subwoofer Application

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

selection of three different 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 butterworth characteristics so that their
