Donner Bluetooth 5.0 Stereo Audio Amplifier Receiver, 4 Channel 440W Peak Power Home Theater Stereo Receiver with USB, SD, FM, 2 Mic in Echo, RCA, LED, Speaker Selector for Studio, Home - MAMP5

The amplifier works great for my setup. We bought a new house that had in-wall speakers but no amp or terminated wiring. This unit handled it perfectly—three groups of two speakers (six total), and it powered them without issue. Just note: while the amp supports up to 8 speakers, it pairs them into stereo groups, so you really get only 2 true "zones" you can independently turn on/off. For example, if you wire the left speaker of Group A and the right of Group C, you’ll need to use both knobs to fully mute that zone. It’s a little unintuitive if you're expecting more zone control. I’d recommend studying the wiring diagram in their product images before setting it up—once you see it, you’ll understand the grouping logic. It wasn't a deal breaker for us, but it’s worth knowing ahead of time. The Bluetooth could be better but it's good enough. My only loss of connection is when I go outside to my patio which is downstairs and in the back yard. Approximately 50' or so and through a couple walls. Separately, love that It has multiple input types for mics, aux, and even has some basic EQ knobs. Great bang for buck IMO!

My previous amplifier was a tube amp. But I burned something out (not a tube, I checked those) and I needed something that was less complicated than my old set up. My old set up was a tube amp for my front Klipches and a Class D amp for the back ones. I also have a 400 watt subwoofer. I used to feed those amps from my computer, which outputs to a discrete DAC. This is for my 10x10 home office, by the way. So I know it's overkill. So anyway - I got the MAMP5 and used 4 channels to bi-amp my front Klipches (these are the ones you can do that on). Then I just did normal 2 channel to the back. I used pre-out to go to my sub. Then I messed around with levels and stuff on the amp and on my sub. Those blue dials on the amp - don't turn them up past about 12 o'clock. Use the little black one on the bottom right to control overall level. The blue dials are just to set "ratio." And you keep them at less than 12 because you want to leave some headroom for loud things in your music. If you hear the fan - that's because you did something wrong. For example, I can make the fan come on by turning the blue knobs to almost zero, then cranking the main volume knob. Because the blue knobs are near zero, there's almost no sound coming from the amp. But it's still working hard. That's because I think the blue knobs basically just work like resisters and the black knob controls the actual amplifier. SO - put the blue knobs near 12 o'clock and the little knob at 9, or 12 if you want loud loud. I think if you turn the bass or treble up too high, that will also trigger the fans prematurely. So it you hear the fan, mess around with the volume & tone knobs. So what does it sound like? My original major in college was audio recording engineer, I used to do sound in a club, and I have done it for live bands, so I think I have decent ears. 1) It's "trebly" - so turn down the treble. This could also be me going from tube to solid state. Either way, turn the treble down a little. 2) bass needs to be turned up a little. 3) Soundstage is good. Instruments and voices appear in 3D space about like I would expect. 4) It doesn't sound grainy. That was my big worry. 5) It's loud AF! If you adjust it right - you actually are getting 50 clean watts per channel. So with me biamping the fronts, I am getting 100 watts to each of those and 50 to each of the rears. These are efficient speakers and I can drive them to earsplitting level with almost no distortion. 6) The remote works, but only controls volume for the bluetooth, USB and card reader and FM inputs. It won't control volume for aux or anything else that is plugged into the back with RCAs. 7) When it does distort, it distorts the way that you would expect from a class-D (I don't think it's A/B for this price). So it's like clean, clean, clean, then holy moly. It's not linear. The fact they put in a loud fan and super ventilated the case tells me this is primarily intended for something like a retail store or a bar. My impression is that it won't prematurely fail. I think it's worth the money.

It works, but... there's bluetooth delay. I had to connect a separate bluetooth relay device. The 440W peak is all show for buyers. I hooked up one speaker and got good bass, but 2? bass vanished. These speakers are like 30 years old too. Too weak. Value for money? ehhh... debatable. It's small, easy to plug and play. the remote works, but not very well. needs line of sight more so than quality remotes.

Exceptional product for the price. Sound clarity and paring ability was flawless. Highly recommend.

This amp receiver has to be the biggest disappointment of an amp that I've ever had. I'm running 2 Jamo tower speakers and 2 very capable Sony reference speakers along with a KLH sub in my garage (see pics). This amp CANNOT push these well at all, despite being advertised with high numbers. Sound is horrible. The EQ settings are on the higher tones. I set the mids and the highs to zero or negative 5, then set the bass to 10 and honestly, there's no bass on my speakers. I bought this to replace my $40 Pyle amp which is surprisingly good with the exception of a very loud fan. It thumps and sounds good with my speaker setup, but the fan noise is annoying with higher volumes. The speaker connections are very weird and surprisingly confusing. It's advertised as a 4 ch amp however, there's 4 sets of left and 4 sets of right speaker connections. Mmmmm, that's 8 channel not 4. I tried several different connection combos but they all just ain't cutting it. On top of this, every channel has a dedicated volume knob. Why? I had high hopes for this amp but it's going back and I'll just keep my cheap but capable Pyle 4 ch amp that pushes so much sound on all levels with clarity at low volumes. I don't know how people are giving 5 stars on this unit. I can't give more than 1 star, just can't. Maybe my unit might be defective, I just don't know. What I know is the unit I have is absolutely trash.

Not sure what product other reviewers received, but pictured is the unit wiring that I got as of 2/8/24. First I tried the bluetooth and I walked out of the room and it played flawlessly so range was not a issue for me. Now for the bad: One would think that since it says "stereo" when you hook up channel A to 2 speakers they would actually be stereo but they are NOT! It is mono. <--this might not be a big deal for most depending on their use, however the only way to get stereo outputs is to use 2 separate channels aka (left & right) In doing this is makes it useless for 4 zones in my opinion. And who wants to control volume left to right anyway (BTW this is why you see no Balance knob) I ended up returning it due to this, who wants a "mono" application, I needed to control 4 stereo different zones, so if that is what you are looking for don't even bother ordering it. I will say however I almost kept it for the bluetooth alone and it does sound a lot better than most older expensive amps. <--surprising good sound and seems to be quality but in the amp world the only way to tell is with time. I hope this helps cut down some confusion on this device and keeps some from making my mistake :) I consider myself above average in wiring amps/DJ booths due to my past so believe me I didn't mis-wire it. It just didn't do what I needed it for :)

This thing is amazing I got it to use 99% with my turntable and am 100% satisfied, sounds better than my other two from 2020. The flashing Bluetooth can be turned off with the remote. I have a pyle and sunbuck receiver and the fm works the same on all three, welcome to 2020 receivers, auto finds 68 stations but about 30 of them are just noise, you use the ch up and down to go through the stations, that said the radio on this receiver sounds better than my other two. I don’t use the Bluetooth on any of my receivers because music sounds so much better if you plug your phone or tablet into the aux input. I even plug directly in to my Bluetooth speakers because they sound better that way. Bluetooth is good for listening to talk radio or a pod cast or old time radio programs but not music. In testing I wanted to see how loud it would crank up in doing so my family all ran downstairs to get away from it, it was so loud it cleared the room, I went into the kitchen to get away and the cabinet doors were rattling from the bass, way louder than I will ever be listening to it. My video doesn’t do it justice sounds so much better in person. Very happy for the price, you can pay way more for one with all the features and power this has.
