The Kroma Telecom Company was established in the beginning of 1996 and today is one of the leading Spanish companies, specialized in developing, projecting and production of the equipment for the broadcasting industry. The activity of the company is focused on the production of the analogous and digital monitor of high resolution, systems of the under monitor indication and systems of service traffic. Nearly 45% of the qualified staff of the company is completely included in the development used in the company's production and introduction of the new technologies. The philosophy of the company is the establishment and support of long-term tight relations with distributors and buyers. That is why Kroma Telecom provides the high level of the technical support, education and fast answer to all kinds of requests to the clients and distributors.

Television Monitors of BM53/BM54 Series

The Kroma monitors are projected so that they would meet the very high requirements. That is why they are based on the module construction, which provides the flexibility at the monitor application. All monitor control handle, including the regulation of the image geometry, are on the front board of the monitor. The composite entry on the front board allows connecting the test generator and other sources easily. The microprocessor-based control gives the opportunity of fast and exact regulation of the majority of the monitor parameters. These parameters can be set by the standard and then easily transferred to the other monitors. The additional SDI module includes the two component consecutive ten-unit color entries (ITU-R BT601 SMPTE/EBU 270 Mbit) and component analogous entry. The module also allows to the user pick out the sound and then to input it in analogous or digital form. The models of BM53 series have the resolution capacity of 650 tvl, of BM54 series not less than 900 tvl. The monitors are equipped with the keyboard, projected to minimize the quantity of the necessary transmissions to the menu. All the main functions are available directly from the front board and do not need the long error in the setting menu. BM53/BM54 have the consecutive RS-485 interface for the remote control. The control panel allows controlling up to 128 monitors with the help of the consecutive cable and at the application of RS-485 protocol for requesting concrete monitors. So all monitors can be controlled at the same time from the board of only one monitor that will be the head facility of the remote control. The additional RS-232 interface is assigned for the connection of the personal computer and allows modernizing the monitor system through the application programs. The monitor can operate with the 4:3 and 16:9 shot formats and in the full raster conditions

The LM5000 Series TFT 9", 15", 18" Monitors

The new specter of LCD monitors of 8,4" (two facilities in 19" body), 15" and 18" are assigned for the reproduction of the TV image in the studios for the application in the broadcasting area. The are LM50 especially famous there, where the space and the power consumption are the key factors. The 8,4" LCD monitor has the display with the resolution of 640 per 480, 15" have 1024 per 768, and 18" have 1280 per 1024 pixels. They have good color rendition. The large viewing angle provides the best perception of the image from any place. The settings of the monitors are controlled by the microprocessor and with the help of buttons situated on the front board all the functions can be easily reached with the help of the screen menu. The numerous additional entry options allow widening the functionality of the monitors. The 8,4" LCD monitor can be powered from the video camera battery and be situated on the place of the fixing of the on camera light. All the monitors are fixed into the 19" standard body or can be situated directly on the desktop. The variants of the monitors for the desktop are accomplished with the inclinable front panel for the better viewing angle. The RS-232 interface provides an opportunity of program modernization with the help of computer. On the front panel the Tally indicator, which can be adapted in three way, is situated. The cutoff point of the external power supply on the back panel is equipped with the screw joint for the prevention of the accidental segregations. The small sizes and weight, minimal power consumption of the monitors of LM50 series and the high resolution are the most appropriate parameters in the situations when the control of the equipment in the limited space is needed. Because of that reason the LCD monitors are very popular in the small studios and systems of the mobile TV stations.

LM5000 TFT series 9", 15", 18" monitors

The monitors of LM5005 series are developed for the most exacting spheres of the television broadcasting where it is necessary to watch after three independent sources at the same time. Each one of the LCD displays has two PAL entries
