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 an RF high-frequency output. It modulates the signal into RF format, reducing transmission loss and extending transmission distance from 1-2 meters up to 100-1000 meters or more. It helps overcome limited input options on older TVs by utilizing the TV's built-in tuner via the antenna input. Compatible with DVD players, set-top boxes, network boxes, game consoles, and similar devices. Equipped with imported RF modulation chip for stable PLL frequency phase-locked output, ensuring consistent frequency without drift. 3. Technical Specifications: RF output frequency: 61.25 MHz and 67.25 MHz (switchable); customizable frequencies between 40-900 MHz available upon request RF output gain: 80 dB RF system output: PAL DK (default); optional I/BG, M/N, L sound systems available; 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 devices output, power it via USB. Connect the RF cable from the converters RF OUT to the TVs RF IN (antenna/cable input). Turn on the TV and switch to analog TV mode. Use the menu button to perform an automatic or manual channel search for 61.25 MHz or 67.25 MHz. Set the TV sound system to match PAL DK. Most modern smart TVs automatically detect the correct sound system. For older TVs, manual selection of DK system is required to avoid audio and video noise.
