*Dynamic Range Control (DRC) is originally the concept of Dolby Digital and used only in Dolby Digital.
But as a similar concept there is the Automatic Volume Correction in the analog TV, and it is used in the same menu 
because there is no possibility of conflict between the two.
Therefore, if you turn on the DRC in the menu, the DRC will be active in the digital TV and AVC will be active in the analog TV.
