2.1 Quick Start
This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview
The VA-1 UXGA Sync Processor is a high-performance sync corrector that
can be used for any UXGA computer graphics video signal. The low-
voltage sync signal is cleaned up and brought to the TTL voltage level
while passing color signals transparently. This is especially useful when
sending a video signal over a long display line.
To achieve the best performance:
Use only good quality connection cables
1
to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables).
Avoid interference from neighboring electrical appliances that
may adversely influence signal quality and position your Kramer
VA-1 away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
2
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
