Donner Bluetooth 5.0 Stereo Audio Amplifier Receiver, Peak power 440 W Hi-Fi Wireless 4 channel Desktop Amp with USB, SD,FM, 2 Mic IN Echo, RCA, LED, Speaker Selector for Studio, Home Speakers-MAMP5

Works well straight out of the box, easy to set up and bluetooth connection to iPhone works a treat. Has four separate channels so you can have multiple speakers around the house with different loudness. We got it for a party, with 4 speakers dotted around the garden and others in 3 rooms of the house, some simply daisy chained one from anther. Power output to this lot was more than enough to get the neighbours grooving along with the guests! We've not been brave or annoying enough to crank it to full volume, plenty loud enough at 50-60%. All round, a nice bit of kit for a reasonable price. The remote works but it wasn't easy to get it working properly and it's not that easy to use - doesn't bother us as we didn't want it for that, but might bother you.

Good product, good price, good seller

After reading the reviews I was hesitant to buy it but overall it’s not a bad product for the price. Downside (as per a number of reviews) the plastic ports broke within seconds - they are really really poor quality. We managed to bodge it so we could use it and not have to return. Other than the flimsy ports it’s a reasonable product with good sound quality and Bluetooth connection - we are a small family so not used at top volume etc. but for background music so far so good

Wonderful machine. I fully recommend it

This is decent And has a great appearance and sounds good lots of controls connects easy to BT and has a good range not bad value for money either I would like it if when you operate the input selector it shows all on the front screen but not a biggy and also the speaker output connectors need to be clearly marked apart from that all good

I was unsure at first that it would do all the things I wanted it to do like connect my record player and my computer to it did that no problem lots of outputs with Bluetooth usb cd video ext , I had to buy a phono mini amp to connect my turntable but that was fine for the money it’s a great piece of kit

Versatile, compact, 8 output connectors, easy to use - excellent value for money!

Received the product, connected the output of my CD player unit to one of the RCA inputs to perform an initial test. The sound quality was not too bad for the price. Then, when disconnecting my high quality RCA cables, from the unit, the two RCA terminals of the input came off.

Gracias, el producto llegó físicamente bien y bien empacado. Regresaré a la reseña en días posteriores para compartir sobre su funcionamiento.

Cet amplificateur offre un son clair et puissant, parfait pour un home cinéma ou une configuration audio domestique. La connexion Bluetooth 5.0 est fluide et sans latence, et les 4 canaux permettent une belle flexibilité d’installation. Avec 1000 W de puissance, il alimente facilement plusieurs enceintes. Un excellent rapport qualité-prix pour ceux qui cherchent un ampli polyvalent et performant. Très satisfait de mon achat !

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.
