Features: 1. Product Classification SCART to RF converter changes SCART interface to radio frequency RF output. 2. Function introduction: This RF converter easily converts your device's interface into RF output, modulating it into high-frequency RF signal. It reduces transmission loss, extending transmission distance from original 1-2 meters up to 100-1000 meters or more. It helps overcome limited input options on older TVs by utilizing the TV's tuner input. Connect devices such as DVD players, set-top boxes, network boxes, game consoles, and more. Converts signal to RF radio frequency output. Uses imported RF modulation chip for stable PLL frequency phase-locked output, ensuring consistent frequency without drift. 3. Technical specifications: RF output frequency: 61.25MHz and 67.25MHz, switchable. (Other frequencies between 40-900MHz can be customized) RF output gain: 80dB RF system output: PAL DK default (I/BG/M/N/L sound systems available for customization). SECAM and NTSC systems can be customized per regional requirements. Power supply: 5V/500mA Power consumption: less than 0.5W 4. Usage and connection: Connect the RF converter to your device's output, using a power source via USB. Connect the RF cable from the converter's RF OUT to the TV's RF IN (antenna or cable input). Turn on the TV and switch to analog mode. Use the menu button to perform automatic or manual channel search for 61.25MHz or 67.25MHz. Set sound system to match PAL DK. Most smart TVs automatically detect the correct sound system. Older TVs must be manually set to DK system to avoid o and video noise. Package Included: 1 x RF Video Converter 1 x RF Cable 1 x USB Cable
