Abstract (en)
[origin: EP1341394A1] An electronic audio signal processing device comprises a first DAC (4) for converting a first digital audio signal into an analog signal, first and second output terminals (11, 12) for outputting said analog signal, a detector (10) for detecting whether a sound generating device is connected to the first output terminal (11) or not, a control unit (9) for setting a characteristic of the analog signal to a predetermined value according to whether a sound generating device is detected at the first output terminal (11) or not, and a switch (8) for disabling output of the analog signal by the second output terminal (12) when a sound output device is detected to be connected to the first output terminal (11). <IMAGE>
