VS SERIES MECHANICAL SWITCHERS This section describes all the controls and connections of your switcher. Understanding the controls and connections helps you realize the full power of your switcher. Getting to Know Your VS-41AV Switcher The Kramer VS-41AV is a high quality, mechanical 4x1 Video / Audio stereo switcher in a compact desktop enclosure. Audio is always switched together with the corresponding video signal, and unselected video inputs terminate into a 75-ohm resistor.
Getting to Know Your VS-101AV Switcher The Kramer VS-101AV is a high quality mechanical 10x1 switcher for composite video and stereo audio signals. It 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 terminate into a 75-ohm resistor. High quality switching components provide excellent isolation between inputs.
Getting to Know Your VS-4X Switcher The Kramer VS-4X is a 4x1 stereo balanced switcher, using professional XLR connectors. The machine is housed in a compact enclosure, using high quality switching elements, and operating in break-before-make mode. Due to the mechanical mode of operation, the machine can be used “ backwards” – also functioning as a 1x4 switcher. Front/rear panel features of the VS-4X are described in Figure , and Table 3.
INSTALLATION Rack Mounting The VS-41AV and VS-4X switchers may be rack-mounted in a standard 19” (1U) EIA rack assembly. The VS-101AV has rack “ ears” at the ends of the front panel. To mount the VS-101AV switcher, simply place the rack ears against the rack rails of your rack, and insert standard screws through each of the four corner holes in the rack ears. The VS-41AV and VS-4X require special rack adapters (see section 4.1).
TAKING CARE of YOUR SWITCHER Do not locate your switcher in an environment where it is susceptible to dust or moisture. Both of these may damage the electronics, and cause erratic operation or failure. Do not locate your switcher where temperature and humidity may be excessive. Doing so may also damage the electronics, and cause erratic operation or failure of your switcher. Do not clean your switcher with abrasives or strong cleaners.
