TM15-70R   15-inch CRT Color Monitor
 

70 Series are High performance, Low cost color SDTV Monitors, providing NTSC-PAL automatic selection. Then Units are specifically designed for production or broadcast applications, and provide high-fidelity video reproduction with wasy operation. utilizing in Line Gun CRT technology, BFS circuits, and Comb filter.

Features

Cathode Ray Tube
  • In-line gun, dot-shadow mask, high resolution CRT, assuring convergence stability.
  • Black Matrix surrounding CRT face assures high contrast under bright ambient lighting.

Circuitry
  • NTSC / PAL format auto detect.
  • Screen aspect ratio of 4:3 or 16:9 switchable on the front panel.
  • BFS (Beam Feed-Back System) provides long-term black level stability.
  • Pre-set Controls: Hue (NTSC Only), Chroma, Y/PB/PR Chroma, Brightness, Contrast
  • Comb Filter provides wide band luminance, switchable to notch filter at the front panel (NTSC only).
  • Sweep failure protection circuit prevents phosphor burns.

System Conveniences
  • 4 video inputs (Ach composite /Bch composite / YC / RGB or Y, Pb, Pr) selection on the front panel.
  • Digital inputs (ITU-R601 format) is optionally available.
  • Rack mounting hardware is also available.

Test Facilities
  • Under scan switch to permit observation of picture corners.
  • Pulse cross switch for sync signal verification.
