PM454   4-in-1 Broadcast Monochrome Monitor

  

The PM454 4-in-1 monochrome monitor contains four high resolution 4.5-inch monitors, mounted in one 19-inch rack.
The PM454 is ideally suited for use as a monitor in a space-Iimited environment, such as a broadcasting van or control room.

  • High resolution 4.5" CRT and a wide-band video amplifier provide a horizontal resolution of 500 TV lines or more.
  • Back porch clamp assures black level stability with varying APL.
  • High voltage regulation circuit is applied to minimize display size variation .
  • All monitor units are completely shielded from each other, and not affected by sync signals of differing type.
  • Markers compatible with the SMPTE Safe Title Area can be displayed (option) .
