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

Press Esc until DP571 Unit Setup: Program Config is displayed again

(home in the setup menu structure). Press the ↓ key until DP571 Unit Setup: Operating Mode is displayed, then press Enter.

Press the ↓ key until Operating Mode: Metadata Revert is displayed, then press

Enter. Use the ↓ ↑ keys to select Metadata Revert: Last Used and press Enter.

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:

Dolby E

 

5.1 + 2

20bit

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.
