Description of the audio processor part
TDA7461
Figure 9.
Soft step timing
1.
For steps more than 1dB the soft step mode should be deactivated because it could generate a 1dB error
during the blend-time.
3.3.4
Bass
There are three parameters programmable in the bass stage (see Figure 10, 11, 12, 13):
●
Attenuation
●
Center Frequency (60, 70, 80 and 100 Hz)
●
Quality Factors (1, 1.25, 1.5 and 2)
3.3.5
DC mode
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.
3.3.6
Treble
There are two parameters programmable in the treble stage (see Figure 14, 15):
●
Attenuation
●
Center frequency (10, 12.5, 15 and 17.5 kHz).
3.3.7
Speaker attenuator
Due to practical aspects the steps in the speaker attenuator are not linear over the full
range. At attenuations more than 24 dB the steps increase from 1.5 dB to 10 dB (please see
data byte specification).
