TDA7409
1.7.4 DC Mode
In this mode the DC-gain is increased by 4.4dB. 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 11. Bass normal and DC Mode @ Gain = 14dB, fC = 80Hz
Note: The center frequency, Q and DC-mode can be set fully independently.
1.8 Treble
There are two parameters programmable in the treble stage:
1.8.1 Attenuation
Figure 12 shows the attenuation as a function of frequency at a center frequency of 17.5kHz.
