The MT-47 modulator is a professional electronic device designed for use in terrestrial television systems and video surveillance installations. It is a double sideband modulator, which means high flexibility in selecting output channels. The main task of the device is to convert an analog audio and video signal (e.g., from an industrial camera, multimedia player, or decoder) into a high-frequency RF signal, which can be transmitted via coaxial cable to multiple television receivers simultaneously.
The device features advanced microprocessor control, which translates into exceptional operational precision and ease of configuration. The output channel selection is performed digitally using two buttons hidden under an aesthetic cover. The current channel number and other operating parameters are presented on a clear LED display, which eliminates errors during installation. Thanks to the use of a quartz frequency stabilization system (PLL), the carrier frequency error is practically zero, which guarantees a stable image without interference and the need for receiver tuning.
A key advantage of the MT-47 model is the possibility of cascading, which allows for the construction of extensive headend stations supporting multiple channels. The modulator also allows for summing the modulated signal with an existing terrestrial television signal, making it an ideal solution for upgrading existing RTV networks. The manufacturer has ensured configuration security by introducing a lock function against unauthorized access. Additionally, the device supports a wide range of PAL system standards, including B/G/D/K/H/I/L/M/N versions and the Australian standard, which ensures full compatibility with receivers worldwide. A solid housing and high-quality F-type connectors guarantee longevity and reliability in continuous operation.

Software and control
The MT-47 device is equipped with dedicated firmware managed by a built-in microprocessor. This system is responsible for precise control of the PLL generator, which eliminates frequency errors and ensures output signal stability. The user interface based on two buttons allows for intuitive navigation through the configuration menu, visible on the LED display. The software allows for digital adjustment of the audio input level, signal deviation, as well as changing the audio subcarrier offset from the video carrier. All changes made are automatically saved in the integrated non-volatile memory, so the device retains full configuration even after complete power disconnection. Additionally, the software implements advanced algorithms for supporting multiple PAL standards, which makes the device universal for global markets.
