5.1 Output configurations
The figure below shows the different configurations supported at PCM output stage. They are selected by the
OCFG register contents.
The same configurations will be used in case of a decoded Pro Logic program with the exception that the sur-
round channels will not be added to the bass redirection (the surround channels of a Pro Logic program are
band limited and bass is considered as leakage).
- In configuration 1, 3 and 4, the main channels are attenuated by 18.5dB, and the LFE by 8.5dB before
- In configuration 2, the main channels are attenuated by 16dB and the LFE by 6dB before processing.
- In configuration 0, outputs are only scaled and rounded (see next section).
PCM OUTPUT CONFIGURATIONS

After digital/analog conversion, the subwoofer preamplifier has to compensate for the different gains
of the main channels and subwoofer.
