Wireless Audio Kit

The 1Mii RT5066R1 set includes one transmitter and one receiver that stream stereo audio wirelessly over 2.4 GHz. It targets users who want to send sound from a TV, DVD or MP4 player to a powered speaker, amplifier or home stereo without running long cables. The kit ships with RCA and 3.5 mm cables, two power adapters and two antennas for immediate setup.

Range and Latency

Outdoors the link reaches up to 320 feet, while indoor coverage falls between 100 and 200 feet depending on walls and interference. Latency stays below 20 ms, keeping audio in sync with video for movies or gaming. The 2.4 GHz band offers strong anti-interference performance, though nearby Wi-Fi routers or metal obstacles can reduce the effective distance.

RCA Connectivity

Both units provide RCA input and output plus a 3.5 mm jack, so they connect directly to legacy analogue sources and powered speakers. No HDMI port is present, so digital-only sources require a separate converter. The system pairs automatically on power-up, delivering plug-and-play operation for stereo audio distribution.

Questions about this item

Will the RT5066R1 work with my older TV that only has RCA audio outputs?

Yes, the set includes RCA cables and a 3.5 mm adapter so you can connect the transmitter directly to legacy RCA outputs on a TV, DVD player or MP4 device.

How can I confirm the transmitter and receiver are paired and passing audio correctly after I plug them in?

The units pair automatically on power-up; verify the link by playing audio and checking that sound reaches the connected powered speaker or amplifier without drop-outs.

What cables and accessories come in the box and what must I provide separately?

The package supplies the transmitter, receiver, two RCA-to-3.5 mm cables, two 5 V power adapters with cables, two RCA cables, two antennas and a manual; you only need a powered speaker, amplifier or stereo system to complete the chain.
