INE OUTPUT SELECT REGISTER
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.

Subaddress 22 (note 1)
Note

The default setting at power-up is 0000 0000.

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, NICAM, I
