AJA D10AD 10-bit Component/Composite to SDI Converter User Manual — Introduction
Introduction
The D10AD provides excellent quality 10-bit conversion of component or
composite analog video to SDI—with EDH. The D10AD accepts YPbPr (SMPTE,
EBU-N10), Betacam, or RGB component inputs and NTSC/PAL or YC (S-Video)
composite inputs. When using composite sources, the D10AD offers a 4-Line
Adaptive Comb Filter for high quality decoding. The comb filter can be switched to
2-line or notch modes for minimum delay requirements. NTSC/PAL configuration
is automatic. Video format, AGC, H/V blanking, and pedestal are all user
configurable via dipswitches.
Note:
The D10AD requires a Time Base Correct source. Operation is not
recommended from VTRs, laser disks, etc., without Time Base Correction (TBC).

User Controls
The user interface for the D10AD is an 8-
switch DIP accessible through a cut-out in the
bottom of the unit. Use the DIP switches to
configure outputs, pedestal, blanking, and
enable or disable comb filter, EDH, AGC, and
test pattern.
Switches 1 and 2 select composite or
component input and the type of component
input. Switches 3 through 8 set configuration
features. The exact function of each DIP
switch and what it controls is described on the
following pages.
Note:
Changing input format (SW1, SW2, or SW3) causes a reset to occur that
takes about 10 seconds to complete.

Installation
Typically, D10AD installation consists of the following:
1.
disconnect +5VDC from the convertor
2.
configure the DIP switch for the desired equipment configuration and video formats
3.
connect video equipment to the convertor BNCs
4.
apply +5VDC power to the converter (AJA power supply model DWP)
