HOMEPM-404
PM404  
4-in-1 Broadcast Monochrome Monitor

 

The PM404 4-in-1 monochrome monitor contains 4 high resolution 4" monitors, mounted in one 19- inch rack. The PM404 is ideally suited for use as a monitor in a space-limited environment, such as, a broadcasting van or control room.

Features
  • High resolution 4" CRT and a wide-band video amplifier provide a horizontal resolution of 450TV lines or more.
  • High voltage regulation circuit is applied to minimize display size variation.
  • All monitor units are shielded from each other, and are not affected by non synchronous signals.
  • Markers compatible with the SMPTE Safe Title Area can be displayed (option).
