SCART Input Prescale
PRE_SCART
Defines the input prescale value for the analog SCART input signal
bit[15:8] 00hex ... 7Fhex prescale gain
examples:
00hex
19hex
off
0 dB gain (2 VRMS input leads to digital full scale)
Due to the Dolby requirements, this is the maximum
value allowed to prohibit clipping of a 2 VRMS input signal.
+14 dB gain (400 mVRMS input leads to digital full scale)

Sound A Mono (or Left Mono)
Sound B Mono (or Right Mono)
Stereo (transparent mode)
Mono (sum of left and right inputs divided by 2)
special modes are available
(see Section 6.5.1. on page 97)
In Automatic Sound Select mode, the demodulator source channels are set
according to Table 2–2. Therefore, the matrix modes of the corresponding output
channels should be set to “Stereo” (transparent).
