Description of the audio processor
As can be seen from the block diagram in Figure 1, the Audio processor is composed of
three building blocks. - The INPUT-Section, the MAIN-SIGNAL-PROCESSING-path and the
OUTPUT-Section.
This chapter will give more insight into the different blocks and describe their function.
5.1
Input section
The Input-Section of the TDA7415CB incorporates three independent stereo signal paths,
where each can connect to a variety of inputs and the AC3 input from the Output-section for
monitoring purposes. For simplicity only the left inputs are shown.
After selection by the Main-, Sub-, and/or Auxiliary-source selector, the signal passes a
gain-adjust amplifier, a soft-mute stage and finally a buffer before it is output at the device
output-pins. The soft-mute circuit will be described later.
Figure 3.

not shown)
