3.5.13 ABUS
When optional audio cards such as the UAP-1781
are used to provide audio signals for embedding in
the DEC-1023’s SDI output, the ABUS audio bus
links the audio cards and the DEC-1023. The ABUS
tab is used to instruct the DEC-1023 about the
presence of installed audio cards.
MULTIPLE CARD CONFIG: The indicators signal
the presence of appropriate audio cards installed in
the Densité frame.
Use the pulldown box and select your system’s
configuration.
• Video – only the input video signal is used,
and no audio will be embedded
• V/ A1 – audio from the external A1 card is
available for embedding in the DEC-1023
output
• Video / A1 / A2 – audio from both external
audio cards A1 and A2 is available for
embedding in the DEC-1023 output
.
3.5.14 Factory
The Factory tab contains a LOAD FACTORY button
and an Auto-Calibration mode button.
Load Factory: Clicking this button will reinstate all
default parameter values. The DEC-1023 Menu on
pages 4-6 shows the default value underlined for all
parameters.
Auto Calibration (Color Bar): If the video input is a
color bar signal, the DEC-1023 can perform an
automatic calibration of it’s decoder function.
• Connect a standard color bar signal to the
DEC-1023 video input
