KRAMER: SIMPLE CREATIVE TECHNOLOGY
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 lowvoltage 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 cables1 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 unit2.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
