3.2 Your VS-81AV 8x1 Video/Audio-Stereo Switcher
The Kramer VS-81AV, 8x1 Video/Audio-Stereo Switcher is a high-quality
mechanical 8x1 switcher for composite video and stereo audio signals.
The VS-81AV is designed for applications requiring an unpowered rack-
mountable unit for routing of video and stereo audio signals. Audio is
always switched together with the corresponding video signal and
unselected video inputs are terminated via 75Ω resistors. High-quality
switching components provide excellent isolation between inputs. Its
unpowered passive design is advantageous for applications in which various
regulatory compliances would otherwise be required. The "hard-wired"
signal path offers excellent bandwidth, and can even switch other signal
formats.
