As long as your source outputs a standard composite video and audio signal, it is compatible with this single channel AV to RF modulator.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I adjust the output channel frequency on this cable TV modulator?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The modulator is frequency adjustable across UHF channels 21–69, giving you full control over which channel your content appears on within your cable TV distribution network. The default factory setting is Channel 21 (471.25 MHz, PAL-B\/G), but you can configure it to suit your specific installation requirements.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this modulator work with both PAL and NTSC systems?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, the Tuoying AV to RF modulator supports both PAL and NTSC video standards, making it suitable for use in a wide range of countries and with various AV equipment. Multiple sound carrier frequency options (M, B\/G, I, D\/K) further enhance its international compatibility.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How is this modulator powered?\u003c\/h4\u003e\n\u003cp\u003eA: It is powered via a standard USB connection (5V @ 400mA), so you can power it from any USB wall adapter, computer USB port, or USB hub — no proprietary power supply needed.
