Note
1.
A possibility to copy from SCART 2 input to SCART 2 output is not implemented.
10.3.19 L
INE OUTPUT SELECT REGISTER
10.3.19.1 Description
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.
10.3.19.2 Definition

Subaddress 22 (note 1)
Note
1.
The default setting at power-up is 00000000.

NAME
HIGH/LOW
FUNCTION
SC2GAIN
HIGH
Activates the 3 dB gain stage at the SCART 2 output port. As any SCART input passes
a 3 dB attenuator, this gain stage can be used to compensate that attenuation, resulting
in a 0 dB insertion loss when copying from SCART 1 input to SCART 2 output.
However, that gain must be used with great care, as it will cause signal clipping at high
input levels.
The audio signal will be output unchanged (0 dB gain).
