The DRC scheme has a single threshold, offset, and slope (all programmable). There is one ganged DRC for the
left/right channels and one DRC for the subwoofer channel.
The DRC input/output diagram is shown in Figure 44.
Professional-quality dynamic range compression automatically adjusts volume to flatten volume level.
One DRC for left/right and one DRC for subwoofer
Each DRC has adjustable threshold, offset, and compression levels
Programmable energy, attack, and decay time constants
Transparent compression: compressors can attack fast enough to avoid apparent clipping before engaging,
and decay times can be set slow enough to avoid pumping.
