Avantree Audiplex - Wireless Audio Transmitter & Multiple Receivers Set for AV Receivers, Projectors, PA Systems, Hearing Assistant in Church, Broadcasts to 100 Multiple Headphones & Speakers

This set is a bit pricey and very specific gear, but they work fantasticly together to provide a super low lag sound field for parties. I bought an extra reciever and use the transmitter connected to RCA's on my TV audio output to have 5 indoor and outdoor speakers. It sounds great!

I have ten receivers which have replaced twisted-pair wire running through the crawl-space under the house to all rooms. All are working flawlessly, with a few comments.One in the garage is about 60 feet and four walls away from the transmitter and I have to lay it just right for it to receive, but that is not a problem, positioned just right it works fine. Incidentally, I put that one in a baggie to protect it from dust.One outside on the patio is about 50 feet, two inside walls, and one brick wall away. It doesn't receive very well behind the brick wall, but there's a window, and when I lay the receiver on the window sill it works. Again, not a problem, and I'd not have expected it to work well through brick.The receivers are a bit fiddly to pair, nothing consequential, you may have to try two or three times, but they all pair quickly.Some of my speakers are switched, i.e. when I turn the lights off in a room the speakers go off. I plugged the receiver chargers into the same circuit and learned that, when the battery runs down and the receiver turns off, then when power is turned back on, the receiver doesn't work until I turn the on-off switch on the receiver off and back on. I resolved this by plugging the receiver charger into an always-hot outlet.So, after a few days, all is well. If they continue to work without failure I'll be most happy.

I saw one comment somewhere that said they were getting latency well trying to pair their Bluetooth headset with these, I don't know what they're talking about because these are not Bluetooth.Well the audio quality isn't crisp I would say it's 95% acceptable and I would love to see what a revision they could do. They're basically analog? No latency! There's lots of scenarios I can think of where I want One Source to many. I was using these will mixing Sound and I was having issues with my low latency Bluetooth transmitter receiver set up so I grab these out of my bag. I was in a big metal square box I walked into the other room another big metal square box to pick up my food order. I was over 500+ feet away before I started noticing any drop outs on the other side of a metal wall!!!!!!!!!!! I still can't believe they worked. I purchased the original version with optical outputs on the receivers in case anybody else is scratching their heads looking at the pictures they did exist. I purchased a second set rather than an expanded set figured the extra transmitter would give me options. I could see them wanting to cost cut, I just hope they make that other receiver available as an extra add-on. I could see a few scenarios where you might want to send optical audio to two different sets of speakers. I can also see weird things like running a dedicated optical DAC with volume control next to the sofa. One point I was thinking of grabbing the optical audio off of the DVD player at my local theater down to a private set of headphones but now that they have finally raised enough money for surroundsound the 1900s speaker has been officially retired and the audio sounds great. I have a few other ideas for these devices one of them is for use on a Sound bag and handing out receivers for interested parties to listen (also thinking of sending a slightly lower audio quality with FM transmitter with the benefit of anybody can bring a radio). And the current situation I'm experimenting with sending Wireless time code, yes it does work although I do need a pad on the signal otherwise it modulates the opposite channel which I am planning to send back up audio over to cameras. At some point I'm gonna get around to making a video comparing different Wireless products audio latency and distance.And to be fair I've had a couple of times where there was probably just way too much interference where are the distance was probably closer to 100 feet outdoors but I was also running consumer wireless guitar units and prosumer wireless microphones and fighting with multiple channels of 2.4 GHz Wi-Fi. I still got Signal through although the orientation and distance was a bit more finicky. Battery life has been great occasionally the switches will get bumped I need to find a better storage mechanism but with three receivers I have a 1 and 4 chance that it's going to be the transmitter. but that can be plugged in well they can all be plugged in while used. When charged battery life is very good I have to remind myself to charge them every so often usually I just try and charge them before I know I'm gonna use it and definitely charge it after I use it but I have not encountered one dying while being used. Don't know what else to say it's the kind of thing that I've been wanting and was actually looking to attempt to build out of premade parts. I took the gamble when they first came out at the price they were and I think the price came down a little bit and now I look at it going no brainer. Well-made, there's solid and I'll probably be buying another set.

Echo. Sonos. Old school Shoutcast. Software galore. Wires galore. The art of playing sound through multiple speakers in a multitude of locations has always been a large PITA. Until now.THANK YOU Avantree, this product works extremely well as advertised and has solved this endless multiple decades old issue with a simple wireless product that simply WORKS. I've been hassling through software repeater software, bluetooth broadcasts, echo relays, sonos speakers, even went through a rack mount audio distribution system to play music throughout my house in different speaker systems for each room. NEVER QUITE WORKED RIGHT. EVER. THere was always a flaw such as delay over here or over there, it was so frustrating to say the least to even get the software based solutions working. Bluetooth range issues, then sync issues, uggh.Enter this product. Turn it on, out of the box, they are linked and voila! My problems have forever been solved. I can't believe it. Lagless, flawless with optical in if I desire and long range with >100 devices? SIGN ME UP! I'm impressed at the price, quality, ease of use, and I would certainly trust my older family to be able to use this blindfolded.Highly recommend for a simple yet elegant solution for audio distribution.
