By definition, the line output conveys the same signal as the Main (loudspeaker) channel, but in a non-processed form.
This register is used to characterize the signal to be output at the line output and define the output channel selector mode.

A signal from an analog source is being processed in the Main channel for line
output. Analog signal sources comprise SCART 1 input, SCART 2 input,
external input and mono input, i.e. any input to the ADC.
A signal from a digital source is being processed in the Main channel for line
output. Digital signal sources comprise FM, I
