AJA D10CEA SDI to Component/Composite Converter User Manual — Introduction
Introduction
The D1OCEA converts SDI video with embedded audio to 10-bit component or
composite analog video and 4 channel balanced analog audio. The video outputs can
be configured as YPbPr (Betacam or SMPTE/EBU N10), RGB, composite or Y/C
(S-Video). Two re-clocked loop-thru SDI outputs are also provided. This versatile
low-cost converter is ideal for video/audio monitoring.
The 4 channel analog audio outputs can be wired in a balanced or unbalanced
configuration. All audio output channels can be selected as group 1-4 from SMPTE
embedded audio. You have four settings of Audio level to choose from.
Output connections for video and audio are available on a 25 pin “D” subminiature
connector. A break-out cable is supplied with the converter for this purpose.
You can configure video and audio from a DIP switch accessed through a cut-out in
the converter’s case.

User Controls
The user interface for the D10CEA is an 8-switch DIP accessible
through a cut-out in the bottom of the unit. Use the DIP switches
to configure video outputs, pedestal, blanking, select audio
channel groups, and set audio level.
Switches 1 through 4 configure video output format. Switches 4
through 8 select the audio channel group and audio level. The
exact function of each DIP switch and what it controls is
described on the following pages.
Switch 1—Select Component (COMPNT) or Composite (CMPSTE) Out
:
Switch 2—Selects YPbPr/YC or RGB Component Outputs
:
Switch 3—Configure Pedestal For Composite
:
Note:
There is no effect with 625 input.

Switches 5 and 6—Select an Audio Channel Group for Output
Together these two switches select the group of audio channels that will be routed to the
XLR connectors on the break-out cable. Each audio group has four channels,
corresponding to the four connectors. The following table shows the group and channel
assignments selected by each switch position for the two DIP switches.

Switches 7 and 8——Select Audio Levels for Output
Together these two switches select audio output levels at the XLR outputs. The following
