The true power of the 2. 0, however, is in the way that flexibility is harnessed through easyto-use on-screen menus and a simple installation and configuration process. Intensive research by Harman Kardon has helped establish the factory settings for many of the 2. 0's options so that they need not be adjusted by most users. However, for the advanced audiophile, or where special system installations require changes to the factory settings, the 2. 0 provides a means to adjust settings that do not normally need any change. [. . . ] If you attempt to select one of these modes when a Dolby Digital or DTS source is playing, the front panel Information Display will flash to remind you of the mismatch.
