10.3.17 SCART 1 OUTPUT SELECT REGISTER
This register is used to define both the signal source to be output at SCART 1 and the output channel selector mode.
Table 41 Subaddress 20 (note 1)
Note
1. The default setting at power-up is 0000 0001.

SC1GAIN
1
Activates the 3 dB gain stage at the SCART 1 output buffers. 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 2 input to
SCART 1 output. However, that gain must be used with great care, as it will cause
signal clipping at high input levels.
0
the audio signal output will be unchanged (0 dB gain)
