48 / 92 page  1998 Feb 13 48 Philips Semiconductors Preliminary specification Digital TV Sound Processor (DTVSP) TDA9875 Table 44 Description of bit SC1GAIN (note 1) Note 1. A possibility to copy from SCART 1 input to SCART 1 output is not implemented. 10.3.18 SCART 2 OUTPUT SELECT REGISTER 10.3.18.1 Description This register is used to define both the signal source to be output at SCART 2 and the output channel selector mode. 10.3.18.2 Definition Table 45 Subaddress 21 (notes 1 and 2) Notes 1. X = don’t care. 2. The default setting at power-up is 00000000. 3. See Table 48. Table 46 Signal source Table 47 Bits B5 and B4 NAME HIGH/LOW FUNCTION SC1GAIN HIGH Activates the 3 dB gain stage at the SCART 1 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 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. LOW The audio signal will be output unchanged (0 dB gain).
