Frequently Asked Questions

Q: What is a TV Link Modulator and what does the Tuoying TLM01 do?

A: A TV Link Modulator converts composite audio/video (AV) signals from a source such as a set-top box, DVD player, or security camera into a UHF RF signal that can be broadcast to standard analog TVs over your existing coaxial cable network. The Tuoying TLM01 supports PAL and NTSC standards across UHF channels 21–69, making it highly versatile for home and commercial distribution setups.

Q: How does the IR remote range extender work?

A: The included IR emitter relays remote control signals from your TV location back to your set-top box or A/V source, even if it is installed in a different room or a locked cabinet. It supports 38 kHz and 56 kHz infrared frequencies, covering the vast majority of consumer remote controls, with an effective range of 8 meters or more.

Q: Which TV standards and regions is this modulator compatible with?

A: The TLM01 supports both PAL and NTSC broadcast standards and is compatible with multiple sound systems including M (4.5 MHz), B/G (5.5 MHz), I (6.0 MHz), and D/K (6.5 MHz). This makes it suitable for use in the UK, Europe, Asia, Australia, and other regions using these analog TV standards. Simply select the appropriate standard for your region using the on-unit settings.

Q: What power source does the TLM01 require?

A: The modulator is powered via a standard USB 5V connection at 400mA — a common phone charger or USB port on your TV or set-top box is all you need. No dedicated power adapter is required.

Q: Can I use this modulator with my SLX or TV-Link system?

A: Yes. The TLM01 features F-female RF input and output connectors and is specifically designed to be compatible with SLX and TV-Link distribution systems, as well as other standard coaxial RF networks.
