11.3 Audio input
The audio input section is on the rear part of the exciter and is directly connected
to the audio motherboard using a strip-line connector. It is composed of two boards
coupled in a L shape and fastened to the part of the rear panel that hosts the
audio connectors.
The first board (Fig. 11-5) contains the trimmers to adjust the levels and the filters
for each input channel. The second board (Fig. 11-6) contains the level regulations
and the switches for the software-based audio configuration.
Figure 11-5
After the necessary processing (filtering, level regulation, selection), the audio
input section passes the signals to the audio motherboard that route them to the
coder card.
