GENERAL
1-1. FEATURES
Foiii' color sv«tems available ;
The monitor can display PAL, SECAM, NTSCsss and
NTSC4.43* signals. The appropriate color system is selected
automatically.
*Asignal of NTSC4.43 is used for playing back NTSC recorded
video cassettes with avideo tape recorder/player especially
designed for use with this sysfem.
The picture can be displayed in blue and black only. This
facilitates hue adjustment and the observation of video
noise.
Analog RGB or component (Y, RY, and B-Y) signals from
video equipment can be input through these connectors.
The built-in beam current feedback circuit assures stable
white balance.
When NTSC video signals are received, acomb filter
activates to increase the resolution, resulting in fine picture
detail without color spill or color noise.
Autbrtiatic terminatibh ol iiNC connectors
The rear BNC input connectors are internally terminated
75 ohms when nothing Is connected to the output connector
(VIDEO OUT). However, this impedance limit is automati-
cally removed when acable is plugged into the output
connector, and the signal is looped-through as it is.
BA standard 19-inch rack inounting ^
^
By using an MB-507 mounting bracket (not supplied), the
monitor can be mounted in an EIA standard 19-inch rack.
For details on mounting, see the instruction manual of the
MB-507.
