TM12-16R   12-inch Broadcast Color Monitor

 

The TM12-16 is a high performance color monitor that meets a variety of applications, not only for broadcasting stations, but also for production and industrial television.

  • In-line gun, 0.36mm dot mask pitch CRT assures fine picture with no convergence drift.
  • Comb filter in the y /C separator circuit provides minimized waveform distortion and assures more than 500TV line horizontal resolution.
  • Feedback Clamp System provides no black level fluctuation and white balance stability.
  • CRT protection circuit protects the CRT from the damage due to deflection failure and over-voltage.
  • The TM12-16 incorporates degaussing circuit. which eliminates the effects of earth's magnetic field.
