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

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.

I couldn’t be happier with the Donner Bluetooth 5.0 Stereo Audio Amplifier Receiver! This amplifier has exceeded all my expectations in terms of performance and versatility. Here’s what I love about it: Powerful Sound: The 440W peak power provides a robust, clear, and crisp sound that fills the room effortlessly.

Bluetooth 5.0 Connectivity: The Bluetooth 5.0 feature ensures a stable and fast connection, making it super easy to stream music from my phone or other Bluetooth devices without any interruptions. Multiple Input Options: The inclusion of USB, SD, and FM options gives me the flexibility to play music from various sources. The RCA and 2 mic inputs are perfect for both music listening and karaoke sessions, which I really appreciate. User-Friendly Interface: The controls are intuitive, and the LED display adds a nice touch. I love the speaker selector feature that allows me to manage my setup with ease, and the echo function for the microphones is fantastic for karaoke nights.

Overall, I’m extremely satisfied with the Donner MAMP5 and would highly recommend it to anyone who wants to elevate their audio experience. It delivers on all fronts and offers great value for the price!

This little amp is not the highest quality but it's good quality, especially for the low price. The one downgrade I've found so far, which I attribute to quality control, is the channel selector knob is slightly misaligned so it actually seems to point to the next selection rather than the one it's on but I can live with that. It also seems rather choosy about usb drives in that I first used an old one I had that worked fine for loading music with my Mac but the amp wouldn't play (as soon as I inserted the drive, it changed out of USB mode)--and the manual doesn't say what format they should be in but I assume it's FAT(32). When I purchased some new thumb drives and loaded music onto one, it played fine. Another feature that may matter to some is that there really are a limited number of inputs, labeled for DVD, CD, Mic and Aux but you can use them for whatever you want. You can also do as I did and buy an inexpensive audio selector switch (I got one with 4 inputs) to jump it to as many inputs as you need. I notice other comments here had some difficulty with the bluetooth but it worked fine for me, easily paring with my iPhone. I'm also impressed with the base and treble controls which seem to have a wide range. Also, some comments talk about the FM radio running out of channels (it takes 50) before reaching the higher frequencies when doing the automatic channel search in setup. I live in downtown San Francisco so we should have lots of FM stations but I ran the channel search with no antenna hooked up in order to lock in only the strongest channels and it reached the 109 mHz band before running out. Quite a few of those it locked onto were mostly static but when I hooked up an antenna (which you have to buy separately) a number of them came through loud and clear enough to be useful.

The Donner MAMP5 has exceeded all of my expectations! I require my music at moderate to full volume and was blown away by the crisp, clear highs as well as room shaking lows! My Donner MAMP5 is running two Yamaha club speakers and two 10" powered subwoofers (Velodyne and Boston Accoustics).... and there is STILL room for another pair of speakers! THIS UNIT WILL RUN 4 SETS OF 8 OHM SPEAKERS... 8 TOTAL! For the price, this compact unit cannot be beat. There are many options for audio input too... Bluetooth streaming from your phone or tablet, MP3's stored on your USB thumb drive, RCA stereo CD and DVD inputs (I am using those inputs for my LCD TV and computer), and an auxiliary input. (I'm playing my Donner electronic drum set through the auxiliary input.) The controls are well laid out, self-explanatory, and easy to navigate through all of the functions. There is a main volume control as well as 4 channels (2 for the left and 2 for the right) that can easily be controlled independently, giving the user the option to fine tune levels between each set of speakers. Great for wiring music to another room if you so wish. For all of the options you get, the price is very reasonable. I am highly satisfied with this purchase! Recommended to anyone looking for a compact stereo unit with a plethora of nifty options!

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!

I bought this receiver as a way to save some money on a replacement receiver I was using for an old set of 5.1 speakers on my home computer. The original 5.1 dvd player/receiver lasted nearly 20 years. This unit worked great for a while, but if you had audio playing, you could hear the unit (maybe fans?) power up within the receiver. When you hit pause, you could hear it ramp down suddenly, too. About a month or two ago there started to be a low-hum in the speakers that I didn't notice initially, but eventually did. I bought this on August 30, 2024 according to my Amazon invoice. It didn't make it to even August 1, 2025 before it started acting up. Now it still works for with a hum...sometimes... There is often a pop from within the receiver and all audio output, including the hum from the speakers stops before it starts again a while later and then repeats this trend. These are not high output or high impedance speakers. They're not pushing a lot of power either, with all knobs set to about 60% since I control the volume from the keyboard. I can get it to work after power cycling a bunch of times and waiting to hear if the hum starts and then a click or just the hum. I'm not happy with this receiver as it was not abused and only did very light duty for a short time before giving up. Would not recommend unless you're in a bind for a short term solution. It supposedly has a 1 year warranty, but there is no way to contact the company about the issue unless maybe through Amazon...

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 :)

I own a small restaurant and this unit was exactly what we needed. We were running our 2 dining rooms', Bose in-ceiling speakers thru a decent Sony home entertainment system receiver and the sound was acceptable, however, I had no control over zones which became a problem when I intalled speakers outside. The outside speakers were different and were barely audible when connected to the Sony receiver. After experimenting with adding a second receiver and connecting those in order to create some zone control, I became so frustrated with the confusion and difficulty of maintaining the setup that I broke down and bought this unit. What a great purchase. Not only do I have four zones which I can control independently but the sound is actually richer and more powerful. The included basic equalizer controls and functionality are more than adequate for my application and these Bose speakers are finally being utilized to their near their full potential. I am so pleased with the result. Remarkable improvement over my previous setup. I should have bought this sooner. It took longer to trim and prep the 8 speaker wires than it did to plug in the unit. connect the wires and find the optimal settings. Super easy. I will add that I am connected from the output headphone jack on a basic laptop to stereo rca plug into the aux input of the unit. My Bose speakers are commercial and are set to 8 ohms.

Seems to be a fairly good simple unit would of been nice if it came with the appropriate plug but that’s neither here nor there
