... TDA7417 4 Description of the audioprocessor 4.1 Input stages In the basic configuration, one stereo quasi-differential, one selectable full-differential and two single ended stereo inputs are available. As Quasi-differential stereo Input (QD) The QD input is implemented as a buffered quasi-differential stereo stage with 100kΩ input- impedance at each input. The attenuation is fixed to -3.5dB in order to adapt the incoming signal level ...
