Need help?Do you have a question about the Sony TRINITRON PVM-20N1E and is the answer not in the manual?
The Sony Trinitron Color Video Monitor, encompassing models PVM-14N1A/14N1E/14N1U, PVM-14N2A/14N2E/14N2U, PVM-20N1A/20N1E/20N1U, and PVM-20N2A/20N2E/20N2U, is a professional-grade video monitor designed for high-resolution picture display and versatile input signal handling. Manufactured in 1995, this monitor series leverages Sony's proprietary Trinitron technology to deliver stable and accurate video reproduction.
The Trinitron Color Video Monitor serves as a display unit for various video signals, offering advanced features for picture quality, signal processing, and user control. Its primary function is to accurately display video content from a range of sources, including video cameras, VCRs, and other video equipment. The monitor is equipped with multiple input connectors to accommodate different signal types, including composite video, Y/C separate video, and analog RGB signals (on specific models).
A key feature is the "Fine pitch Trinitron picture tube," which ensures a high-resolution display with more than 500 TV lines of horizontal resolution at the center of the picture. This contributes to sharp and detailed images, crucial for professional video applications.
The monitor incorporates a "Comb filter" that activates when NTSC video signals are received. This filter enhances Y/C separation, reducing common artifacts like cross color and cross luminance phenomena, thereby improving overall picture quality.
For consistent color performance, a "Beam current feedback circuit" is built-in, assuring stable white balance over time. This is vital for maintaining accurate color reproduction, especially in environments where color consistency is critical.
The monitor supports "Four color system available," capable of displaying NTSC, PAL, SECAM, and NTSC4.43 signals. The appropriate color system is automatically selected, simplifying operation for users dealing with diverse video standards. The NTSC4.43 system refers to an NTSC color system where the subcarrier frequency is modified to 4.43MHz, typically output when playing back NTSC recorded video programs with a Trident (PAL/SECAM/NTSC4.43) VTR.
The Trinitron monitor is designed with user-friendly "On-screen menus" that allow for easy adjustment of various operational settings. These menus enable users to control parameters such as sound volume, contrast, brightness, color intensity, color system, and menu language. The settings and adjustments made through the on-screen menus are retained even after the monitor is turned off. A "FACTORY PRESET" option is available within the USER MEMORY menu to reset all settings to their factory defaults.
The monitor's front panel includes "LINE A," "LINE B," and "RGB" (on specific models) buttons for input selection, allowing users to easily switch between different video sources. "MENU" buttons facilitate navigation through the on-screen menus, while "POWER" switch and indicator control the monitor's power state.
For installation flexibility, the monitor supports "EIA standard 19-inch rack mounting" using optional mounting brackets (MB-502B for 14-inch models or SLR-103A slide rail for 20-inch models).
The manual emphasizes several maintenance and safety guidelines:
The monitor's "Automatic termination" feature (for connectors with a specific mark) simplifies cable management by automatically terminating input connectors at 75 ohms when no cable is connected to the loop-through output connector. This termination is automatically released when a cable is connected to an output connector.
The "RGB SYNC menu" (on models PVM-14N2A/14N2E/14N2U/20N2A/20N2E/20N2U) allows users to select the sync signal source when RGB signals are input, offering options for external sync or sync on green. The "ASPECT RATIO menu" on these models enables selection between 4:3 and 16:9 aspect ratios.
Overall, the Sony Trinitron Color Video Monitor series is a robust and feature-rich display solution designed for professional video monitoring, offering high picture quality, extensive input compatibility, and user-friendly controls.
