It is possible to lessen the effect of the Blue D-Sat or Gold 6dB setting in this case by simply reducing the level of the analog signal feeding the AD converter to control the amount of saturation effect.

It is possible to lessen the effect of the ‘Blue D-Sat or “Gold 6dB setting in this case by simply reducing the level of the analog signal feeding the AD converter to control the amount of saturation effect. This also reduces the over-all level, so digital gain must be used after encoding to raise the peak level to maximum. If the input level is reduced by less than 6dB, there is still additional level added to the program material once the digital gain is applied.</div></td><td class='diff-marker'> </td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>#If the ‘Blue D-Sat or ‘Gold 6dB setting is enabled while feeding the AD high average level program, the audio can sound too distorted.

Digital gain is applied after this process to raise the over-all signal level by 6dB, so the peak level once again reaches 0dBFS at the digital output of the converter.
