3.1 Your VS-44AV 4x4 Video Audio Matrix Switcher
The Kramer VS-44AV 4x4 Video Audio Matrix Switcher is a high-quality
mechanical 4x4 matrix switcher for composite video and stereo audio
signals. The VS-44AV is designed to simultaneously route up to 4 sources
each to any one of 4 available outputs. The VS-44AV is unique in allowing
4 different cross points of video and stereo audio to operate at the same
time. However, it cannot simultaneously distribute an input signal to
multiple outputs. The high-quality input selector buttons are color coded for
easy identification and unselected inputs are terminated via 75Ω resistors.
Figure 1 and Table 1 define the VS-44AV 4x4 Video Audio Matrix
Switcher.
Table 2 gives the technical specifications for the VS-44AV.
