Description of the audioprocessor
TDA7418
4.8
Treble
There are two parameters programmable in the treble stage:
4.8.1
Attenuation
Figure 16 shows the attenuation as a function of frequency at a center frequency of
17.5kHz.
Figure 16.
Treble control @ fC = 17.5 kHz
4.8.2
Center frequency
Figure 17 shows the four possible center frequencies 10k, 12.5k, 15k and 17.5kHz.
Figure 17.
Treble center frequencies @ Gain = 14dB
4.9
Speaker attenuator
The four speakers have independent soft step speaker controls. And their attenuators can
be adjusted from +15dB to -79dB with 1dB steps.
4.10
Subwoofer attenuator
The Subwoofer output is a single ended mono output. The attenuator is exactly the same
like the other speakers.
