3 Overview

The Kramer VS-41USB is a high quality 4x1 USB mechanical switcher. It accepts up to four USB inputs and switches the selected input to the output. Its unpowered design is advantageous for applications in which various regulatory compliances would otherwise be required.

Achieving the best performance means:

• Connecting only good quality connection cables ^1 , thus avoiding interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables)
• Avoiding interference from neighboring electrical appliances and positioning your VS-41USB away from moisture, excessive sunlight and dust
