Multichannel Wireless Audio Receiver/Amplifier for Making Passive Speakers Wireless - Model 880, Compatible with Model 800 Multi-Channel Transmitter, Better-Than Bluetooth Digital Wireless

For those who complain about a hissing in their speakers when no sound comes out, these come with a volume control. With volume control all the way up, yes, there is the hissing. Why you would ever need the receiver volume that high is beyond me. I have my 880 receiver volume a bit below half, no noise, and the sound is so much louder than my Yamaha receiver puts out, I only have to turn the Yamaha receiver volume up half of what I used to. The sound is crisp and clear, no hiss, and gives great amplification to my Yamaha receiver. I can’t believe I waited so long to purchase these. Highly Recommend.

Below is the old 3 star review - Be sure and read the Update I had a set and one had continuous popping noise (like a capacitor charging and discharging). Many people complain about this but I took a chance and ordered one replacement. No popping noise. Works great. Used in surround sound system for surround (left and right side) speakers (all others are wired). This was the best and only real option I could find and it works great. The are about 13 ft. away with no obstruction from transmitter. I believe as long as you do not unplug the power supply from the receiver module (unplug from wall only) you should be fine and should not develop the popping sound. I've had the set for over a year and a half. The noise started after six months when I unplugged them numerous times. One never developed the noise. Some complained theirs started as soon as they connected them. You are taking a chance, but from what Ive read about the other option is it pops too. I rate this particular module three stars because although it works great now, I can't trust it yet. Ill review this a year from now. WAIT A MINUTE..... UPDATE: I haven't used these for over 7 or 8 years because another one smoked and its just not a sound investment to keep buying replacements when they are so unreliable. So I've just gone back to 5.1 and in fact I don't use surround sound much any more unless its a difference maker for the sake of enjoyment (like a star wars, etc). If you buy these, don't expect it to last more than 6 months and I would recommend protecting them with a UPS on each one, LOL!! What I'm saying is don't bother - hard wire it or nothing. They are too expensive and having nothing is better than having these. This is downgraded from a 3 to 1 star until somebody tells me they started using quality parts with a protection circuit built in.

The Amphony R880 receiver, used in conjunction with T800 transmitter, does what it is advertised to do. When comparing this to the Amphony 1800 kit, the R880 seems to be a much better unit for a number of reasons: the sound quality is better to my ears; it has greater reception range; a total of four additional receivers, thus up to four additional speakers can be used where the 1800 kit allows only two. The last reason allows one to create a wireless 5.1 or a 7.1 surround sound system, assuming that one already has an audiovisual receiver (AVR) system and a subwoofer. Product support through the vendor "HiFi Corner" is outstanding! If you should have a question about what unit to buy, or how to use it "HiFi Corner" is ready and able to assist you.

Note: The fullfiller they are using will sit on your package for days before actually shipping the product out. Doesn’t matter if you pay for expedited shipping, it will sit at their location for a few days with nothing but an automated shipping label to fool you. On the product side, I order 4 and only 3 worked. The 3 that work are decent with little audio drop out once I positioned them in line sight. Now waiting another week for a replacement while it sits in their warehouse.

Parts of me want to give this 5 stars, because it solved a critical problem I had and I am now happy with the final result. Music and surround sound from movies now work perfectly on two speakers for which I could not run wires back to the AVR. Other parts of me want to give it 2 stars, because it was such a hassle to get it working and the 800 transmitter meant to go with this pair of 880s did not work so well. I decided to stick with 4 stars for this unit, docking 1 for a hum in the working configuration (see below), and I'll separately rate the 800 more poorly (but it has its strong points too). Because you need a transmitter with these, be aware of this. My configuration: I live in a rural area, so there is no interference from neighbors. I don't know if that matters, but I have seen some reviews here with range or interference and suspect that might be why. I have an Onkyo AVR with hard-wired speakers for center and front L and R. I needed a way to get a signal to a smaller pair of Klipsch R41M surround speakers located on the other end of a room, about 20' and 30' away (one on the same wall, one diagonally opposite). Running wires without their looking terrible or spending thousands of dollars was impossible. I did already have electrical outlets near where I wanted the speakers -- obviously, you do need to plug in the receiver for power. I originally ordered one 800 transmitter and two 880 receivers, one for each surround speaker. After pairing them, which just took a few seconds, everything seemed to work. Amazing, right? Well, except when I moved everything to its final position, I found I had to ensure the transmitter and receiver were within line of sight, which complicated the layout a little bit. Still not too bad. Then I found that if anyone walked near the speakers, that also knocked out the audio (not permanently, just while the person was in the way). So it was fine for watching a movie with everyone sitting down several feet from the surround speakers, but if anyone got up and walked by a speaker, the audio would cut out while their body blocked the signal. For music especially, which treats the surround speakers as just another left and right pair, this was really bad. I contacted the company for support. They eventually suggested I try the black TX1 transmitter with the old iPhone mount (yeah, weird to include an old iPhone mount and probably the main reason I didn't go with that in the first place) instead of the 800 (as of this writing, that is not available as a stand-alone purchase on Amazon, but looks like the unit in the combo package at https://www.amazon.com/Wireless-Amplifiers-Model-Better-than-Bluetooth/dp/B01ARM0VE0). Unlike the 800, this unit does not suffer cut-outs when people walked around them. The only downside, and the reason for 4 stars instead 5, is after switching to the TX1, there was a hum, a hum that was not there with the 800. It's not so loud that you'll notice it much while audio is playing, but it's annoying if the Amphony system is on but no audio is playing. You can hear it anywhere in the room, about as loud as a refrigerator running -- not terrible, but not ideal. So, it's either use the 800 and have the audio cut out when people mull around, or use the TX1 and get a modest hum. Work-arounds and my final solution: 1. If you can put the 800 and 880 so nobody can get between them, true line-of-sight (like ceiling mounts), then there's really no problem at all. Just be aware that the 800 -> 880 connection is very sensitive to anything getting between them, especially at 20-30' distance. 2. If you have an AVR with adjustable volumes per speaker (I think most AVRs do support this), you can turn the TX1 volume down (the silver dial on the front of the unit), turn down the volume on your wired speakers down in your AVR's setup system, and turn up the volume output to the Amphony-connected speakers in your AVR's setup system. This mostly eliminates the hum, at the cost of effectively lowering the total volume of your system. This is the path I took, having many watts of volume to spare from the Onkyo. 3. The manufacturer offered another solution involving opening the TX1 and making a change but said this would void the warranty. If it weren't new and still under warranty, I might try this, but option #2 worked well enough for me that I decided against this. However, if you're desperate to clear a hum, contact the manufacturer support and ask about this. The problem, at least for me, was in the TX1 NOT in the 880 receivers.

I purchased the transmitter along with an 800 Receiver and two 880 receivers so I could avoid running speaker wire across two doorways. The concept sounds amazing, but the reality is that the equipment doesn't work as described when you live in an area where there are other wireless networks. When I hooked the equipment up, the speakers had a high-pitched buzz and the music kept dropping out. I consulted the troubleshooting guide and slowly worked my way through all of the recommended fixes. I relocated the equipment, I added surge protectors, I moved my wireless network to a different band (which slowed down my network and caused problems with the rest of my wireless equipment that took some time to resolve). I upgraded all of the speaker wire and re configured my stereo setup. But none of these fixed the problem, so I called Amphony technical support. When I described the situation and all of the actions I had already taken, the tech support guy said it sounds like the equipment is working as expected and that because I live in a high-rise in the middle of a densely populated city, there is just too much interference for this equipment to work. Unfortunately, by the time I got through all of the troubleshooting and equipment configuration, I was already past the 30 day return window. Amphony told me that no customer would want to purchase equipment that had already been in use by another customer for over 30 days. I honestly had to laugh at that. The equipment is cheap plastic like something you would buy at Radio Shack for $15 and the speajker wire they send is low quality. I'm out $300 and doubt I'll be able to sell this equipment on eBay. I'm sure Amphony was just glad to make the sale and it doesn't surprise me they don't want their equipment back. If you live in a remote area, this might work for you.

I bought a similar set of these (1800) kit in 2019. They worked great out of the box up until about November 2021 when both units stopped working. Given they are independent of each other and they both seemed to do so at the same time my theory is that a power surge was the culprit. So i bought two 880 units and a adopted a much better electrical set up/power surge protector to try and avoid this. For a week both worked great but then one unit started having issues. From describing the issues to the seller they suspect a faulty power source damaged the unit and replaced it. I haven’t installed that one yet but there is a one year warranty and a two month return policy so I’m not worried about actually getting it right. NOW THE IMPORTANT PART… bespoke home theaters/surround sound that use wireless connections (especially for passive speakers that need amplification) aren’t as simple as other wireless things like bluetooth headphones or so. It takes some creativity, patience, luck and troubleshooting to maybe get it right/operational when you are dealing with other interference from about everything that is wireless these days and that’s even before you get into the unique electricity needs for something that is both wireless and has a built in amplifier independent of the speaker. If that’s too much for most, get a blue tooth sound bar with a matching sub woofer and get on with it. But if it’s not and you want a more classic 5.1, 5.2, 7.1 or 7.2 system with wireless surround speakers And/or sub (s) this seller (who is about the only person except a best buy house brand that even tries to make these) does a great job re customer service imo and that’s worth the price of these in itself. But remember creativity, patience, luck and troubleshooting if it doesn’t all perfectly come together 5 min after you open the boxes!

I purchased this item on March 24, 2018, to replace the pair of amplifiers I bought 2 years before this date. Now, February 2021, They have again "failed" - one unit is totally dead, the other unit has a varying volume, effectively making it useless. When they worked, I used them for surround sound, where audio quality is not critical, so I can't attest to their fidelity. But having to replace them every 2 years is unreasonable. I contacted Amphony, and paid 40$ a unit, total $80 for refurbished replacements. The replacements worked well, but how long will they hold up?
