The Kramer VS-81AV is a high quality mechanical 8x1 switcher for composite video and audio stereo signals. It is designed for applications requiring an unpowered rack mountable unit for routing of video and audio stereo signals. Audio is always switched together with the corresponding video signal, and unselected video inputs are terminated via 75 ohm resistors.

High quality switching components provide excellent isolation between inputs. The VS-81AV is extremely rugged and dependable. Its unpowered, passive design can be an advantage in applications where various regulatory compliance would otherwise be required. The "hard-wired" signal path offers excellent bandwidth, and can also switch other signal formats.
