Description
The GC-AV02 AV to RF Signal Modulator is a sophisticated device designed for seamless transmission of audio and visual signals within both PAL and NTSC systems. Engineered with MCU controlled PLL technology, this modulator ensures high accuracy and stability of visual carrier and audio subcarrier. With selectable audio subcarrier frequencies of 5.5MHz, 6.0MHz, and 6.5MHz, it provides flexibility to meet varying transmission needs.
This modulator is equipped with an RF loop input, which automatically stores settings in the event of a power outage, safeguarding your configurations. The LED channel number display enhances usability, allowing for easy channel selection. Furthermore, the double side band modulation technique enables non-adjacent frequency usage, making it an ideal solution for various broadcasting environments.
