Introduction
Overview
The ADC-9033 Analog Composite/Component/YC to SDI Video Converter is a
high-quality signal conversion solution within the growing family of GearLite
compact, self-contained modular products. Supporting NTSC, PAL-B, PAL-M,
PAL-N (combinational) analog composite video standards, and RGB and
YPRPB analog component inputs, the ADC-9033 is the ideal analog to SDI
converter for virtually all video conversion requirements. All analog RGB,
YPRPB, and YC video formats are supported, with the converter powering up in
the previously selected standard, format and level. All units ship set to 525
YPRPB component for SMTE levels.
The ADC-9033 provides high-quality conversion into four separate 270Mbps
SDI coaxial outputs. The use of a 10bit A to D converter and circuitry, along
with a high-quality 3-line adaptive comb filter, ensures clean conversion of
composite signals. Proc amp controls on the front edge enable adjustments to
the signal in the digital domain. The chassis front edge also provides power,
error and function LEDs for visual reference.
A universal power adaptor and line cord, suitable for the country of use, is
supplied with each module. Various mounting options are included that enable a
wide range of installation choices.
The GearLite ADC-9033 is a high-quality universal analog to SDI video
converter making it an ideal solution for existing analog facilities in a growing
SDI world.
