Description of the audio processor
TDA7419
4.6.4
DC mode
It is used for cut only for shelving filter. In this mode the DC gain is increased by 4.4 dB. In
addition the programmed center frequency and quality factor is decreased by 25 % which
can be used to reach alternative center frequencies or quality factors.
Figure 12.
Bass normal and DC mode @ gain = 14 dB, fC = 80 Hz
1.
The center frequency, Q and DC-mode can be set fully independently.
4.7
Middle
There are three parameters programmable in the middle stage:
4.7.1
Attenuation
Figure 13 shows the attenuation as a function of frequency at a center frequency of 1 kHz.
