First of all, before use, please connect your audio output device (TV, PC, etc.) to your powered speaker through an audio cable to confirm that your devices can be used normally. 2. Then, connect the RT5066Pro receiver to your powered speaker. If it is an optical jack, please use an optical cable. If it is a coaxial jack, please use a coaxial cable (not included). If it is a 3.5mm jack, please use a 3.5mm audio cable. If it is an RCA jack, please use an RCA to 3.5mm audio cable. Note: If an RT5066Pro receiver is connected to 2 powered speakers at the same time. Please use optical and coaxial jacks. Because the optical and coaxial jacks are digital signal outputs, and the 3.5mm jack is analog signal output, they cannot output at the same time. Either only choose 3.5mm output, or you can choose one or both optical and coaxial outputs; if you use 3.5mm and optical (coaxial) at the same time, your powered speakers will have no sound. 3. Next, connect RT5066Pro transmitter to your audio output device (TV, PC, etc.) and select different audio cables according to different audio ports (same as in the previous step). 4. Finally, connect RT5066Pro receiver and transmitter to power and they will automatically enter the pairing state. (Flashing red and blue light turns to solid blue light)Pairing successful. Note: If the RT5066Pro receiver and transmitter cannot be paired successfully, you need to find the small hole next to the indicator light, press it for about 2 seconds, release it when the receiver and transmitter slowly flash blue lights at the same time, when the blue light of the devices are always on, it is successfully paired.

    • Works Great for Connecting Receivers Wirelessly!
These work great for connecting my various audio/video receivers throughout the house! My main video receiver is a 4-zone Yamaha where I connected the transmitter to the Zone 2 Pre-amp output. This is in the basement inside a wall cabinet where I put the transmitter also. In my office, I've got a 1980 Yamaha stereo amplifier and one of the receivers. I connected one of the receivers to the Aux 1 input. I've got a Sony A/V receiver in the living room with another TV connected to it. I connected the other receiver to the Tape 1 input. Any input I choose on Zone 2 of the Yamaha is now transmitted wirelessly to the other two. I can adjust the volume of the remote systems either manually at the volume dial for each or by using the Yamaha app and changing the output volume of Zone 2. The sound quality is excellent, and I've not had any dropout problems. I highly recommend this setup for similar applications. I can now listen to my Spotify playlists on the old 1980 stereo system! The kit comes with 1 transmitter, 2 receivers, 3 power bricks, 3 USB A to USB C cable for the power. Also included are 3 optical cables, 3 mini to mini cables, and 3 mini to stereo phono cables. So no matter what combination of connections you need, this kit has you covered. For my application, I used the 3 mini to phono cables. The pairing between the transmitter and receivers is fast and automatic. There is a manual override to retry the pairing if there is a problem, but I have not needed to use that. I highly recommend this for audiophiles. ... show more

    • Music throughout my house now.
Works great, both receivers connected right away. I installed the transmitter on zone 2 on my stereo. One receiver connected to Klipsch R-51PM speakers in my in the next room. Second receiver connected to my basement sound system so I can now have the same music throughout the house. I give the manual 2 stars though. It's one that has 8 languages on a page for each step. Does not tell you what a flashing red light means. (not connected to a receiver) ... show more

    • Unwilling to help with return after missing date.
Won't let me return because life stressors put me 2 days past the return date. Expensive and brand new, absolutely stupid. So irritated with the customer service options on this.

    • Great product, one small gripe...
Pros *Easy to setup, plug and play. , if it doesn't work out either receiver/transmitter off and on. And it should, connect almost instantly (solid blue led mn both devices) *Well constructed, all metal casing and came with all the wires you need. Including TOSLINKS. *No latency issues, I have not (2 subs in use) had one issue connectivity wise. Cons *Only one really, the output signal towards the receivers seems very low. I had I up my subwoofer channel significantly. To get to the thx reference level I had before using the transmitter/receiver combo. That's the only gripe I have, it's a very good solid product for the money spend. I hope they last. Relatively, small and super easy to get it to work. And it does as advertised.. ... show more

    • Background hiss in receivers.
It transmits audio fine, but there is a slight hiss in the background of the receivers. If used for low volume background music, it's fine. That's what I'm using them for so I kept them. But for high volume serious listening, you'll need to spend much more money on a higher quality system.

    • RCA connection doesn’t work.
I ordered this to drive 2 powered subs in my theater. I used the RCA connectors for both the transmitter and receivers. They paired with no issue but only static came out. I thought I had a defective unit so I ordered a replacement which arrived the next day and I got the same results, only static. I had read the instructions and they didn’t provide any guidance on which of the 3 provided cables to use: RCA, 3.5mm and optical. I tried the 3.5mm cables on both the transmitter and receivers and they worked. Can’t say I was thrilled about the hassle but I am happy with the product. ... show more
