C
Turn off power to the input and output devices, and
disconnect their power cords.
N
The MVX matrix switchers can also switch component
video, S-video, or composite video with the appropriate
adapters.
a
Video inputs — Connect RGB video sources, as appropriate to
your switcher's video format and matrix size.
b
Video outputs — Connect RGB video displays, as appropriate
to your switcher's video format and matrix size.
N
Most laptop or notebook computers have an external
video port that may require special commands to output
the video to that connector. Also, a laptop’s screen shuts
off once the external video port is activated. See the
computer’s user’s guide for details, or contact Extron for a
list of common laptop keyboard commands.
N
The MVX VGA 128 A does not have the Sync Impedance
switches described below.
c
Sync Impedence switches (168, 1212, and 1616 matrix sizes) —
The Sync Impedance switches compensate the output 1
through 8 impendance for different cable types and lengths.
Each switch provides the option of selecting either 50 ohms or
75 ohms. The 50 ohms position is required only when a sync
problem is encountered. The normal position is 75 ohms.
N
An input producing an out-of-sync display — a display
that is rolling vertically and/or tearing horizontally —
could indicate an impedance problem.
d
Audio inputs — Connect audio sources to the 5-pole captive
screw connectors.
