Setting Dolby Pro Logic Delay
The channel delay function for Dolby Pro Logic exists for a somewhat
different reason than for Dolby Digital. There is a different default
surround delay value than that for Dolby Digital. Dolby Pro Logic does
not require a center channel delay. The factory preset delay default
values are Center = None and Surround = 30mS.
