Introduction
Overview
The ADC-9032 Analog Composite 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, the ADC-9032 is the ideal
analog to SDI converter for virtually all composite video conversion
requirements.
The ADC-9032 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-9032 is a high-quality universal analog to SDI video
converter making it a perfect solution for existing analog facilities in a growing
SDI world.
