Making connections and rear panel settings
C Turn off power to the input and output devices, and
disconnect their power cords.
N Video connectors are grouped by video plane.
Connect the input or output on each video plane
to the corresponding connector in the correct
group. Refer to the CrossPoint 450 Plus /
CrossPoint Ultra / MAV Plus Switcher
Manual to connect the various video formats to
and from the various models if you are not sure.
a
Video inputs — Connect RGBHV, RGBS, RGsB,
RsGsBs, component/HDTV video, S-video, or
composite video sources, as appropriate to your
switcher model's video format and matrix size.
b
Video outputs — Connect RGBHV, RGBS, RGsB,
RsGsBs, component/HDTV video, S-video, or
composite video displays, as appropriate to your
switcher model's video format and matrix size.
c
Sync termination switches (CrossPoint switchers) —
Set the switches as necessary to condition non-TTL sync levels
greater than 5 Vp-p. Sync termination enables the sync to be
properly passed from input to selected output(s).
N CrossPoint 450 Plus switchers have Sync termination
switches for inputs 1 through 8.
CrossPoint Ultra switchers have Sync termination
switches for inputs 1 through 4.
The matrix switchers have two sets of sync termination
switches; one for horizontal or combined sync and a second
set for vertical sync.
510 ohms — The default position, suitable for most video.
75 ohms — Typically required only for an input with non-TTL
sync (greater than 5 V p-p).
N An input that produces an out of sync display, a display
that is rolling vertically and/or tearing horizontally, could
indicate a non-TTL sync input. If you are not sure, check
the specifications in the user’s manual for the input device.
