3.2 Button Functions

Each button on the front panel controls a function or functions in the DP564. These

functions are defined in this section.

Any time a feature is active, the front-panel button associated with that feature is lit.

This is true whether the feature is activated or deactivated manually, or controlled by

program metadata, GPI/O, or a preset configuration.

The primary function of each button in this group is printed on the button. To perform

the alternate function (printed on the panel above or beside the button in yellow text),

press Shift, then the button associated with the desired function. When you press

Shift, that button stays lit until you press another button, or press Shift again to disable

the alternate-function selection.

In this group of buttons, there is one function that goes beyond navigation: Bypass. If

the DP564 receives a PCM signal while in bypass mode, it passes the signal straight

to the Left and Right channel outputs with no processing. If the DP564 receives a

Dolby® Digital signal, it decodes the signal, but all further processing is disabled.

This includes dialogue normalization, dynamic range control, and downmixing, as

well as all surround formats, bass management, and channel delays. Channel level

trims and master volume continue to function. When you select Bypass (Shift, then

Esc), bypass mode remains in effect until you disable it by using the same button

combination. When you disable bypass mode, the unit returns to the settings in effect

when you entered bypass mode.

The navigation buttons work in combination with the display screen menus. In setup

menu screens and the Metadata Status, Error Status, and System

Status screens, pressing Enter enters the submenu for the highlighted selection, and

pressing Esc returns to the next higher menu level. If you are at the top of a menu

structure, Esc has no effect. If you change a value for a parameter in the setup menu,

Enter activates the new value and returns to the next higher menu level, and Esc

discards the new value and returns to the next higher menu level. For details on menu

structure, see Chapter 4, Menus.

The default menu at startup is the status menu. The status and setup menus have

separate functions and structures, detailed in Chapter 4, Menus. If you are in a status

menu, Setup changes the display to a setup menu. If you used the setup menu within

the previous five minutes, it returns you to the last setup menu you saw. If you have

not used a setup menu within that time, pressing Setup displays the top-level setup
