WiFi & Bluetooth 5.0 Stereo Digital Amplifier Receiver for Home Audio BGM Music System, MUZO App Control Multi-Room Sync, Compact with USB/AUX/Mic, Remote Control with Sleep Timer

I had a 20 year old Elan whole house music system in my house that finally bought the farm from a Florida lightning strike next door. The system has 7 stereo pair of in ceiling speakers and 18 mono speakers around the house with 18 Elan impedance matching volume controls over all. The Elan provided one source feed to whole house audio, doorbell functionality through the speakers, and whole house phone line based intercom. All gone finally with one blast from the sky. And there is no real replacement for this functionality as almost no one uses regular phones anymore.I have quotes from local integrators in one case for almost $14k with 18 Sonos amps which retail at $600 each and a ring doorbell with 4 chimes.So I was looking around at my options to get some of my functions back or expand them a bit but $14k seemed a little steep and lightning strikes twice around here.And then i found this little amp controllable by app Muzo from my phone on the wifi with a paging function priority mike input built in as well. One of these will run each of the stereo pair more than loud enough. And with an add on amp the line out from one of these KeiiD amps will feed the rest of the mono speakers. Right now my first Keiid is easily driving a stereo pair and working fine with the Elan volume control. And through the Muzo app all play the same track from a variety of sources. High quality sound output for whole house purposes. FM works fine.And with an Alexa echo spot plugged in to the mic in priority jack I can stream anything from Amazon music or more importantly use it to announce throughout my whole house from any Alexa or my phone Alexa app. Just took a 3.5mm to 1/4 adaptor. I say "Alexa announce dinner is ready" and the music pauses from any source and the whole house hears it.With multiple Keiid amps I now have more sources I can feed to each stereo pair and I only paid $86 for this with a coupon and special promotion. Even at $129 a great value way better than Sonos $600 option. And the ring doorbell I installed now announces through the whole house speakers thanks to Alexa and the echo spot. About all I lost was the phone line based intercom but I get that back with Alexa drop in if I need. The bluetooth range is much better than expected as well working through walls and multiple stories.They have multiple streaming options for sources and can switch to line input for an old CD changer as well as stream ANYTHING through Airplay off my phone. And from a music server and USB flash drive as wellThis is a very versatile little device and the priority mic announce is a real plus as well.Happy to answer any questions.

It's nice and compact for all the things it does. It does everything that it's advertising, but you should know that while there is an external volume control, there is also an internal volume control that is controlled by the remote. If you set the volume at 15 with the remote, be prepared for a shock if you keep it connected to an external amp because it's going to come on at 30 (maximum) when you switch on the hard power button. If KEiiD is reading this, please make the default 15 or maybe even 10. The solution is to just leave it on all the time, or remember to turn the physical volume nob down before you turn it off. If you use an external amp and an outside source like Bluetooth or AUX input, remember to turn the volume down on those devices before shutting down so that you aren't caught off guard when you turn everything back on.The tone nobs are a nice way to make global adjustments on your source media before it goes out to your external amp or speakers. The physical volume nob does not adjust volume for externally provided media before it goes out the preamp outputs on the way to your external amp, but the volume nob does adjust the internal tuner volume before going out to your external amp. So does the remote controlled volume. For external sources, and speakers connected directly to this amplifier, you can use either internal or external volume controls.The FM tuner seems to work pretty good inside my apartment building. It has concrete floors and metal studs. I didn't try the AM tuner. There doesn't seem to be an HD tuner on the FM. I've got an Amazon Echo-dot connected to the AUX inpunt and it works really nice for that, in fact, it prompted me to sign up for the Amazon Music Unlimited service which has iHeart radio included. (that's another review).I actually bought two of these. I've got one in the bedroom and one in the living/theater room. In the bedroom, my nightly routine is putting on some boring droning music or using my "Ambience" app to play a rainstorm with far off thunder. Although this product includes a sleep timer, I set the phone app to stop after 30 minutes and by that time, I've fallen asleep. I don't think the power draw is that much on standby, so I just leave the unit on all the time. It never even gets warm.Overall, it's a great product. I'll be recommending it to my friends.
