one-touch recall of a complete set of parameter settings previously stored as a preset.
Output-level controls set the volume level for your listening environment. Detailed
explanations of each button function follow.
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.
3.2.1 Navigation
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
