DP564 Multichannel Audio Decoder Menus
4-14
Clock
Use the
Clock
menu to select the clock source for the DP564.
Digital In
locks
the system to the currently selected digital input (AES1, AES2 or Optical).
Ref In
locks the system to the reference input (
AES Ref
) 1 . When locking to the reference
input, sample rate converters are available if the digital input and reference input
sample rates do not match.
Ref In–SRC On
applies sample-rate conversion (SRC)
to the digital outputs.
Ref In–SRC Off
, locks to the
AES Ref
clock but bypasses
SRC processing.
IFE Mode
Use the
IFE Mode
menu to enable and disable in-flight entertainment (IFE) mode.
IFE mode sends the Dolby Headphone signal to the DP564 outputs.
Note: IFE mode is not a normal monitoring mode. None of the
Monitor
Configuration
settings are applied in this mode.
Monitor Out
Use the
Monitor Out
menu to designate whether the
Master Volume
knob controls
the analog outputs only, or both the digital and analog outputs.
Bypass
The
Bypass
menu controls whether bypass is E
nabled
or
Disabled
.
You have easiest access to the bypass function by using the front-panel
Bypass
control,
Shift
+
Esc
. When in bypass mode,
Esc
is lit.
GPI/O Configuration
Use the
GPI/O Configuration
menu to set up parameters for a dedicated
hardware remote controller. For details on configuring your device, see Section 6.2,
Hardware Remote Control.
1 If the
Streaming
input is selected with the clock source set to
Digital In
, the DP564 uses an internal clock at
the sampling rate indicated by the streaming data.
Ref In – SRC On
uses the reference internal and output clocks.
Ref In – SRC Off
uses the
AES Ref
input for internal and output clocks but requires that the reference sampling
rate matches that indicated in the streaming data.
