Figure 2-1 — Mounting the switcher
3. Drill 1/4" (6.4 mm) deep, 3/32" (2 mm) diameter pilot holes in the table or
desk at the marked screw locations from the underside/inside (concealed
side) of the furniture, where the switcher will be located.
4. Insert the four wood screws into the pilot holes. Fasten each screw into the
installation surface until just less than 1/4" of the screw head protrudes.
5. Align the installed screws with the slots in the mounting brackets, and place
the switcher against the surface, with the screws through the bracket slots.
6. Slide the switcher slightly forward or back, then tighten all four screws to
fasten it in place.
Cabling and Rear Panel Views
All connectors are on the rear panel. The switcher can be connected to up to 12
S-video, composite video and/or stereo audio devices, depending on the model.
All switcher models output two parallel video and/or audio outputs. S-video
models encode one of the two video outputs as composite video. RCA audio
models output one of the stereo audio outputs, unbalanced or balanced, on captive
screw connectors and the other audio output, unbalanced, on RCA connectors.
Figure 2-2 shows an SW 4AV composite video and audio switcher. Figure 2-3
shows an SW 12SVA RCA S-video and audio switcher. All of the switchers are
housed in the same 1U enclosures, but have more or fewer input connectors to
accommodate the different configurations they provide. The two switchers shown
have all of the connector types that are available in the SW AV product family
covered in this manual.
Some devices, such as VCRs, can be connected to both video input and audio input
connectors of the switcher. Others, such as tape players or CD players, can be
connected only to the audio input connectors. An audio device and a separate
video device can share an input, although the switcher is capable of switching
video and audio separately (audio breakaway).
