TDA7417
Description of the audioprocessor
4.3.3
Low & high frequency boost
Figure 6 shows the different Loudness shapes in low & high frequency boost.
Figure 6.
Loudness Attenuation, fc=2.4kHz
4.3.4
Flat Mode
In flat mode the loudness stage works as a 0dB to -15dB attenuator.
4.4
SoftMute
The digitally controlled Softmute stage allows muting/demuting the signal with a I2C-bus
programmable slope. The mute process can be activated by the I2C-bus. This slope is
realized in a special S-shaped curve to mute slow in the critical regions (see Figure 7).
Figure 7.
Softmute-Timing
Note:
Please notice that a started Mute-action is always terminated and could not be interrupted
by a change of the mute -signal
