2 Getting Started

We recommend that you:

•Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

•Review the contents of this user manual

Use Kramer high performance high resolution cables

2.1 Achieving the Best Performance

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)

•Position your Kramer 4x1V and 4x1VB away from moisture, excessive

sunlight and dust

4x1V and 4x1VB - Overview 3

3 Overview

The KramerTOOLS 4x1V and 4x1VB are high-quality 4x1 mechanical switchers

designed for composite video signals using RCA or BNC connectors. They accept

up to four inputs and let you select any input to be routed to one output using

buttons located on the front panel. High-quality switching components ensure

minimal crosstalk and a high bandwidth of 400MHz (-3dB).

The entirely passive design of the 4x1V and 4x1VB eliminates the need for a

power supply. Unselected inputs are automatically terminated into a 75Ωresistor.
