3.5.8 The
Reference
group
This group of parameters allows the selection of
the reference to be used by the XVP-1801.
Use the radio buttons in the Reference Source
area to select from the following options:
•
Auto – this mode selects the first source
detected in this order of priority:
o
External Reference input
o
URS
o
Selected Input signal
•
External – selects the signal connected to the
rear-panel REF IN connector
•
URS (Universal Reference Signal) – selects
the internal reference from the backplane
•
Input – uses the currently-selected input
signal.
URS Format – use the radio buttons in the URS
Format area to select whether the URS is OFF,
29.97 Hz or 25 Hz.
•
When URS is OFF, the URS reference
format source cannot be selected, and will
also be ignored by the automatic detection mode.
3.5.9 The
ABUS
group
When companion audio cards such as the DAP and
UAP are used to provide additional audio channels,
the ABUS audio bus links the installed audio cards
and the XVP-1801. This panel, called ABUS group,
is used to instruct the XVP-1801 about the presence
of installed audio cards and the system
configuration.
Multiple Card Config
sub-section
A1/A2 Presence
: Monitors the presence of
companion audio cards installed in the chassis (see
section 2.2 XVP-1801 Installation).
E1/E2 Presence:
Monitors the presence of Dolby-E
decoding modules installed on companion audio
cards installed in the chassis.
Card System Config: To enable the audio bus, use
the pull-down box and select your system’s
configuration. Selecting Video restricts available
audio signals to audio signals on the video card;
Video / A1 or Video / A1 / A2 adds the audio
channels incoming from the installed audio cards
detected.
