Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!
Getting Started

•Avoid interference from neighboring electrical appliances that may adversely influence
signal quality.
•Position your Kramer VIA GO² away from moisture, excessive sunlight and dust.
