2 How to Use
3 Audio Jack
Q1 How can I be sure that the 1Mii RT5066Pro is compatible with my system? A1 Please confirm whether your audio source has Optical, Coaxial, RCA or 3.5mm AUX audio output interface. And please confirm whether your audio system has Optical, Coaxial, RCA or 3.5mm AUX audio input interface. Q2 If I need to use RCA or coaxial connectors, do I need to buy additional audio cables? A2 If your device has an RCA or coaxial interface, since the package does not come with coaxial audio cable, please purchase them separately.But we have provided 2RCA to 3.5mm cable for your transmitter and receiver. Q3 Can RT5066Pro 2 in 1 be used with any type of speaker? A3 If your audio source device is a powered speakers, it will work fine. If it is a passive speaker, please connect the receiver to the amplifier, and then conenct the amplifier to your passive speakers. Tips:It is not receommended to use with subwoofer. Q4 What should I do if the receiver and the transmitter cannot connect? A4 Please reset the transmitter/receiver: Press and hold the small hole of the transmitter (receiver) with a needle or sim card pin for 2s until the indicator flashes blue slowly. Wait until the indicator turns blue-pairing is successful. Q5 Why is there no sound? A5 Plug more than one audio cable at the same time may cause no sound, please ONLY use Optical/Coaxial jack or ONLY use 3.5mm jack. Make sure the audio cable are plugged into the correct audio jack and plugged fully (you can unplug and plug again) . Q6 Why is there common ground noise? A6 If you plug the power cord directly into the USB port of your device, it will cause common ground noise.Please make sure to use the included power adapter for power supply, this way will eliminate ground loop noise.

Thrilled! Performs Great!
I relocated my television to another wall away from my stereo components and needed a way to still enjoy my built in surround sound ceiling speakers. These little units come with EVERYTHING you’ll need. I used the optical cables from my TV and to my Yamaha receiver, but I’ll likely change to coax due to the higher bandwidth. I plugged each unit in and they paired automatically in about 2 seconds. It transmitted perfect stereo sound with no latency, or sound degradation. These performed flawlessly! They are built well with an aluminum case and a single indicator light. The power button is aluminum and it has a solidly built and adjustable antenna. My transmission distance is only about 12-15 feet, but I didn’t have to buy and pull cables through the ceiling and walls. It requires you to set your TV to PCM digital output, so I know I don’t get actual surround sound, but I still enjoy a greater sound experience through my stereo. There are HDMI transmitters, but they cost much more. For a living room these are great. Spend more if you want a true theater experience.

Awesome wireless HIFI connection to my avr
This has easily been one of my best Amazon purchases this year. Truly plug and play right out of the box.I had been struggling getting HIFI audio from my desktop to my avr. Actually the quest continues as every device and system is hard at work downmixing and or coloring one’s audio from download to speakers. For me, this device eliminated a big gap in my audio data flow — I didnt want to entrust the signal to wifi or ethernet or run wires across my large living and study. I run these – receiver and transmitter all day and night and they perform flawlessly. I connect to them from my win laptop ( using wasapi exclusive mode in my AIMP music player) to an external usb audio DAC and from it to the transmitter via coax (only coax and hdmi can transmit 32 192k without issue). From there it goes on its own point to point 2.4g channel to the receiver which I then connect to the avr via coax. The result is beautiful hifi audio faithfully transmitted without downmixing or degradation. I recommend this device highly.

Didnât work for me
Did not work correctly even tried a second set. Had ground noise coming through and would not connect between sender/receiver
Amazon Customer –
Easy to set up, signal strength seems to match specs.
Works great streaming with a direct line of sight approximately 150 ft apart. I have digital signal feeding the transmitter and analog coming out of the receiver. I have the boxes in remote / difficult to access areas and I was worried that the devices would power off if not receiving a signal but they seem to stay on as long as they are powered. Very happy with it so far.

Connecting between buildings, very powerful. YMMV.
I just set this up. WOW. This goes way beyond eliminating stringing wires across the room. I’m listening to my turntable which is in another building adjacent to the one I’m in. I used the SPDIF output on the interface to connect to the transmitter – it automatically recognized that I was inputting via digital rather than analog. The receiver is at least 100 feet away with 3 walls in between, but the turntable audio sounds crystal clear. That’s connected via the analog output. I’m super happy with how versatile these boxes are – juggling multiple audio formats, and connecting between buildings. I was skeptical this would do what it said it would do, but it does. The boxes are also a little heavy, they seem very solid and well built.

Constant noise with no sound on
Build quality seems good, all cables included, easy setup, but there’s a constant low rumble when connected to a sub and powered on. Unacceptable for wireless sub use.

Worked great across the room via TOSLINK or coax, but converted all to 24bit/44.1kHz.
Rather than route 30 feet of optical cable around the room from my home theater PC (HTPC) to my digital to analog converter (DAC), I opted to try this wireless optical/coaxial receiver/transmitter set. The set transmits stereo PCM signals, so the output device needs to be set for 2 channel PCM output; 5.1 surround sound is not supported, and neither is SACD (Super Audio CD). I used a DVD-audio/SACD player as well as JRiver Media Center from the HTPC as audio sources, and a Benchmark DAC2 HGC as the digital to analog converter. The Benchmark DAC2 displays the bit depth and sample rate it is receiving, and I compared the bit rate and sample rates from the sources to those the wireless receiver fed into the DAC.The set comes with a pair of optical cables, a pair of 1/8″ stereo to RCA cables, and a pair of 1/8″ stereo to 1/8″ stereo cables. It does not come with digital coax cables, but these can be obtained inexpensively if needed. The set also includes two USB-C to USB-A cables and two USB-A power supplies. A user manual and troubleshooting manual are included.The manual states that the frequency used is 2.4GHz, and so should not be used close to a wireless router since it may interfere. The troubleshooting guide states that walls can interfere with the signal transmission of the audio signal.Upon turning the transmitter on, its LED flashed blue and red. Upon turning on the receiver, both turned blue after about four seconds, indicating that they had paired successfully.Using the optical and coax connectors, the sound quality through my DAC was excellent. I was unable to hear a difference between using this device and connecting directly to the home theater PC or DVD-audio player.There were two issues with these devices, however, that keep it from getting 5 stars:1) Via the analog audio output, there was audible background noise.2) The transmitter converted all digital signals to 24bit/44.1kHz, whether a CD quality (16bit/44.1kHz) or DVD-audio quality (24bit/96kHz) piece was being played. More attuned ears than mine might hear a difference. I could not.I’d recommend this as an alternative to anyone who needs to transmit a stereo audio signal across the room via optical or coax cabling, with the caution that, if all samples of this item are like mine, the bit depth and sample rate will be changed to 24bit/44.1kHz.
