Use Kramer high performance high resolution cables
2.1 Achieving the Best Performance
To achieve the best performance:

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.
