Review: Does what advertising says - happy with outcome. - UPDATE Dec 2024 - I have now owned this set for almost 4 months. It still passes bandwidth to the amp that far exceeds my hearing. The received lives outside and has seen near 100 degree days, and now near freezing nights. It still pairs within seconds and works just like new. I am still very happy with it and highly recommend. Original review - Sept 2024. I have a 1990's "stereo/amp" that far exceeds most current soundbar options. I can play FM, Vinyl, Tape, TV Surround, Dolby, Streaming stereo, and more. I wanted to send ANY of these to an outside amp on my deck, without drilling holes and running wires. This set was the answer. I attached the transmitter to the "monitor out" port on my main audio amplifier, and attached the receiver to the outside amp's input. The devices are about 20 feet apart, and paired within seconds of power-up. The audio is slightly lower than other options on outside amp, but since I can now play ANY of my audio sources from the master audio switching amp, it's not an issue. This could be because of the level I am feeding the transmitter. The transmitted audio range seems fine, and I did not notice any latency or other problems. For MY specific setup(older equipment), I had to purchase a set of RCA to RCA cables, but everything else was included. I am very pleased with the build quality, functionality, ease of set-up and value of this item.
Review: After 3 years it’s working great! - Works as advertised - I use it to wirelessly connect a projector to a Bose 2.1 system. It’s easy to set up - mine paired right out of the box. Very occasionally, (maybe 5 times in the 3+ years I’ve been using it) one of the units won’t pair and needs to be reset. Easily done with a paper clip to push the tiny button on the front of the unit. I haven’t noticed any issues with audio quality, noise, or drop outs. I’d happily buy again.

## Questions & Answers

**Q: Can this connect to speaker output for rear speakers?**
A: The input is for a line level out from a sound source BEFORE an amplifier. IF you are looking for something to use on the speaker side of an amplifier this WILL NOT WORK.

**Q: I tried using this for a bose bass 500 subwoofer which has a 3.5mm audio plug at each end, but it didn't work.  bose may use a special signal. ideas?**
A: This is designed for a line out from the source to the amp. It uses RCA jacks. If you are using between amp and speakers, that is an amplified signal and most likely overdriving this unit. Just my thoughts.  Hope this helps.

**Q: Is it possible to get replacement antennas for the RT5066? Mine are missing.**
A: I am not sure but I don't see why not. You can use other antenna that fits the thread.

**Q: Can you buy an extra receiver? I need 1 transmitter and 2 receivers.**
A: The product we don't sell separately comes in a complete set.

### ⭐⭐⭐⭐ Long distance - No Latency
*by D***N on October 3, 2022*

For years I have been looking for a way to connect a portable speaker to my whole house audio so that I can have the exact music playing on all the hardwired channels, and also on a portable speaker out in on the grill island, etc. I tried many bluetooth devices and they all basically lack range, and the latency is always terrible. Even the latest aptX LL devices get out of sync with the digital signal and have drops, latency and plain old poor range through walls, when repositioning, etc. The 1 Mii 2.4 Ghz transmitter/receiver are a perfect solution. Plugged the transmitter into an output on my whole house audio. Grabbed a powered (bluetooth) speaker with an Aux in and plugged the receiver unit into Aux. (Not using any bluetooth.) I powered the 1 Mii receiver unit from a portable 5V power supply charger, so I did not need an outlet. Went to the furthest corner of my yard, maybe 100 feet through a cabinet, 2 interior walls and 1 thick stucco exterior wall, and it worked perfectly. I could even walk around with music playing without missing a beat. No latency that I can tell, and strong signal. Stereo audio sounds perfect. I will do a distance test later and possibly add to this review. And I am also going to try to power the 1 Mii receiver from the powered speaker at the same time as running the speaker, because most of these little speakers also act as a power bank. I will see how long the setup will run that way. Bottom line - I am throwing away the terrible bluetooth transmitter/receivers I invested in, and getting more of these to do dedicated wireless audio connections! Update 11/4/2022: Does not reconnect easily. Sometimes I need to re-pair the transmitter to the receiver. Very annoying. Dropping a star.
