Getting Started

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

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

Warning – Disconnect power and unplug unit from wall

before installing or removing device or servicing unit.
