    ... The volume of the headphone is controlled by an external potentiometer. The TDA1388T has special sound processing features for use in CD-ROM audio applications, which can be controlled by static pins or microcontroller interface. These functions are de-emphasis, volume, bass boost, treble, ...

    ... Flat/min/max setting selection In the TDA1388T has three setting for the digital sound features bass boost and treble. The possible settings are called ‘flat’, ‘min’ and ‘max’. The flat setting has no influence on the audio signal, the minimum setting has a small influence on the audio signal and the maximum setting has a large influence on the audio signal ...

    ... Bass boost A strong bass boost effect, which is useful in compensating for poor response of portable headphone sets, is implemented digitally in the TDA1388T and can be controlled in the microcontroller mode. In the static-pin mode, the flat setting is fixed. In the microcontroller mode, valid settings range from flat (no influence on audio) to +18 dB with step sizes minimum and to +24 dB with step sizes maximum ...
