Table 23 3D Stereo Enhancement Function

When 3D enhancement is enabled (and/or the tone control for playback) it may be necessary to

attenuate the signal by 6dB to avoid limiting. This is a user selectable function, enabled by setting

ADCDIV2 for the record path and DACDIV2 for the playback path.
