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.

### ⭐ NOT suitable for subwoofer use
*by C***S on January 27, 2023*

I bought this device with the intention of using it to convert a custom home subwoofer into a wireless one. I noticed 2 major issues when using this product 1. There is a HUGE volume loss. I believe one of the other reviewers stated it had about a 10 db loss, which sounds about right. You really have to crank the gain up to get it to match a normal wired input level. 2. Loss of low frequency audio signal. This was a deal breaker for me. When running back to back comparisons from wired to wireless, I noticed the bass sounded super anemic when using the 1mii. Even after cranking the volume to match the wired level, I found that there was a ton of bass missing, I would guess around the 25hz - 50hz range. It was still audible, you could tell it was "there" but it had no depth and was almost muted. You couldn't "feel" it like how it is with the wired setup. The build quality felt great but this device should not be used for a subwoofer setup.
