TM20-17RA   17-Series 20-inch Color Monitors

 

Ikegami 17 Series are High performance, Low cost color Monitors, providing NTSC-PAL automatic selection. The units are specifically designed for production or broadcast applications and provide high-fidelity video reproduction with easy operation, utilizing In-Line Gun CRT technology, BFS circuits, and Comb filter (NTSC only).
The 17 Series Color Monitors can accept 2 composite video, Y/C, and RGB or Component inputs in both NTSC and PAL formats. Furthermore, Digital Inputs (D1, D2, D3 formats) are available with optional modules.

Features
Cathode Ray Tube

  • In-line Self Converging Electron Gun assures convergence stability.
  • Black Mattix surrounding CRT face assures high contrast under bright ambient lighting.

    Circuitry

  • NTSC-PAL mode selection
  • Screen aspect ratio of 4:3 or 16:9, with front panel switchable.

  • Pre-set Controls: Hue (NTSC Only), Chroma, Y/PB/PR Chroma, Brightness, Contrast
  • Comb Filter provides wide band luminance, switchable to notch filter at front panel (NTSC only).
  • Sweep failure protection circuit prevents phosphor bums.

    System Conveniences

  • 4 Video Inputs (A/B/YC/RGB or Y, PB, PR), with front panel switchable.
  • Digital Inputs (DI or D2 and D3 formats) are available with optional modules.
  • Horizontal Time Constant can be selected in either 0.5msec. or 2msec.
  • 13V and 19V Rack mount units available.

    Test Facilities

  • Underscan switch to permit observation of picture corners.
