9. Verify that the Metadata Revert and Source parameters are in the correct mode.

Press Esc to return to the Operating Mode: Metadata Revert screen. Use the

arrow keys to display the Operating Mode: Metadata Source screen, and press

Enter. Use the arrow keys to select Metadata Source: Internal and press Enter.

Selecting the Program Configuration automatically sets the associated Dolby

Digital metadata parameters for that program but they can be modified under

the DP571 Unit Setup: Metadata Params menu.2 (See Section 3.2.4 -

Metadata Params.)

10. Return to the status screen by pressing Shift + Setup.

11. The DP571 is now set properly.

12. Headphone level can be accessed by pressing Shift + Enter (the headphone

icon is below the Enter key) and adjusted with the arrow keys. Other than

Headphone Mapping and Level, and Voiceover, the DP572 has very few set-

up parameters that require user attention because it is almost completely config-

ured by the DP571.

13. Like the DP571, pressing Shift + Setup returns the DP572 to the main Status

Screen. The display on both units should now show:

Both units are ready for testing.

2. Example: In 5.1 + 2 mode, Program One is 5.1-channel, and Program Two is 2-channel.

Each of these programs has its own Dolby Digital Metadata. Similar to a DP569

Dolby Digital encoder, a unit placed into 5.1-channel mode (3/2L) automatically

loads a table of metadata values. In 5.1-channel mode, acmod is set to 3/2L, the LFE

is turned on, etc. In two-channel mode, acmod is set to 2/0, the LFE is turned off, etc.

The same thing occurs in the DP571 when the Program Configuration is changed.
