20-Series High Resolution Color Monitors
TM20-20RH/RP, TM14-20RH/RP

20-Series Color Monitors
The 20-Series color monitors are Auto Setup broadcast
monitors designed to meet today’s demanding
professional needs with state-of-the-art digital
technology.
With optional plug-in decoder borads, the 20-Series
will accept different TV standards (NTSC, PAL-B,
SECAM, PAL-M, D1, D2, D3) which can be selected
(NTSC, PAL-B, SECAM, PAL-M: automatically
selected)
!In-line gun CRT with fine dot pitch shadow mask.
!Auto setup module are standard.
!Beam Feedback System (BFS)
!Infrared Remote Controller (Option)
!Optional adaptive comb filter
Features
High Performance Cathode Ray Tube
!Fine Dot Pitch Shadow Mask results in high resolution. Dot trio pitch
0.31mm for TM14-20RH/RP and 0.43mm for TM20-20RH/RP.
!In-line Self Converging Electron Gun assures convergence stability.
!Controlled Phosphors to ABS or EBU Standards provide consistent and
known colorimetry.
!Black Matrix surrounding Phosphor Dots assures high contrast under
bright ambient lighting.
!13V and 19V units available.
Digital Control System (DCS)
The preset control system is completely digitized with the 8 bit MPU and
the 10 bit D/A converter. It enables several status indications, and auto
setup capability with an optional PROBE (ASP-15C). Since a rotary
encoder for preset controls and variable resistors for manual controls
(CONTRAST,, BRIGHTNESS, CHROMA, HUE) are provided, the 20-
series monitors can be adjusted in the same manner as conventional
analog-controlled monitors.
Auto Setup System
By using an optional Auto Setup Prove (ASP-15C), the following
functions can be automatically setup at a reference level or stored in less
than 50 seconds.
!CONTRAST !CHROMA !RGB BACKGROUND
!BRIGHTNESS !HUE(NTSC) !GB GAIN
Remote Control Operation
An infrared remote controller (RCT-20) is provided as an option. With
each of them, the following functions can be remotely controlled for up
to 99 monitors.
!DEGAUSS !DEALY SELECT
!VIDEO SELECT !APERTURE ON/OFF

Beam Feedback System(BFS)
To insure long-term black level stability, the 20-series monitor incorporates
Beam Feedback System(BFS) which detects CRT cathode current deviation and
eliminates brightness changes due to changes in CRT emission.
Adaptive Comb Decoder*
By incorporating a CCD 1H delayline into the standard comb filter, cross
luminance and cross color are improved over conventional monitors. In
addition, by replacing it with an optional Adaptive Comb Filter Decoder*
(NTSC only), performances of 20-Series are significantly improved for
precision color monitoring or graphics display.
Improvements include:
!Chroma edges are greatly improved by patented process based on use of
luminance transitions.
!Dot crawl at chroma transitions is eliminated.

Wide Range of Input Capabilities
The 20-Series can accept 3 composite video inputs and an RGB or a component
(Y, R-Y, B-Y) input as standard. Optional plug-in decoder boards are available
for Digital (D1, D2, D3), PAL-B, SECAM, PAL-M TV standard systems.
Modular Concept
The 20-Series provides modular construction for ease of repair and adjustment.
The boards of video system are plug-in, and many of the boards can be removed
with the monitor mounted in a rack.
