Facmogu F900S 160W Bluetooth 5.0 Mini Amplifier, 80Wx2 2.0CH Audio Power Amplifier, Hi-Fi Stereo Sound Digital Amp Wireless Speaker Amp Receiver w/AUX/USB/BT Input & 12V 5A Power Adapter - Silver

I bought the 2 channel 80Wx2. I had an old bookshelf stereo system that was in a state of decline. The CD player skipped, I didn't use the dual tape deck or the radio anymore. The speakers were still good. Rather than pay a fortune for a new home sound system, I decided to trash the multiplex unit and keep the speakers. The look and size of this unit are perfect. I installed it with double sided tape on the back of one of the speakers connected the speaker wires plugged it in and turned it on. Functions well, Bluetooth connectivity is fast and easy. The power is perfect. The compatibility is great with my various sources. The quality of the sound is hands down better than when connected to the old stereo due to the Bluetooth technology. Very satisfied with this product.

Awesome! This is a Lil Powerhouse. Does exactly what I wanted. Easy to set up with just my limited amount of audio experience, I wanted to salvage a really good set of computer speakers, to use for my Apple TV, But the ATV does not have any Audio out. Only a HDMI port. The 3rd time/try was a charm, My 1st try, was a bluetooth Receiver, no luck(very, very low output). My 2nd Try, A HDMI audio extractor with various adapters & cords. Still low output! Eventhough, I thought my Powered speakers were fairly loud, by themself. My 3rd Try Was this this amplifier. Finally, Success!! Very happy with the results! And pretty Loud, for a welcomed change. I finally figured out, I needed a Booster/Amp to Boost the signal from the hdmi port &/or Bluetooth signal. This lil Amp did the trick! My apple TV went from weak & muted TV speakers, only made worse by My 1st, 2 "weak" attemps only getting really low output, while trying to fix that with other gadgets, to a Now "It's Too Loud" remedy! very happy with the outcome! So far the bluetooth is working well (a good fix to what I thought was an overcomplicated problem). Plus I found it very easy to setup (30 min. or less). This little, inexpensive box was a great answer to what I over thought as a chaotic messy problem! I Highly reccommend to get one!

The power output rating of 80W per channel is based on 24V input and 4 ohm speakers. The power supply provided is 12V and most home speakers are 8 ohms, bringing the rated power output down to 20W per channel. This is still loud. I measured around 84 dBA average playing a rock song (Great Van Fleet). If you buy a 24V DC, 5A or more power supply you can get more volume. I measured around 91 dBA with same song. This is not specific to this product; nearly all mini amps of this type work the same way. I have had this mini amp just over a month. I use it exclusively via Bluetooth paired with a set on Affinity speakers to play backing tracks for guitar practice. It pairs every time and works great for the price. Audio EQ is not great, especially in the bass and presence ranges but mids through treble are not bad. Does the job it is intended for, very compact with a big knob on the top for volume control, good value for the price.

Nice unit, I used for an easy diy portable AMP build, using marine quick connect pigtails for the speaker connections & I can plug it into a house outlet for power OR use my cordless power tool battery + power supply converter that converts my 20v Bauer Harbor freight battery to useable 120v home outlet (limited amps and watts) but it’s within spec of this amplifier and working no problem for me. Awesome purchase I recommend to anyone looking to power a few speakers. I have sets of speakers all over the house, shop, hot tub, gym, camper ect… that quick connect into my portable amp box here when I want to use them. Because I will never be using them at the same time so why buy a million amplifiers. The Bluetooth is pretty snappy and has been working harmoniously with a lot of different devices in the time I’ve used it. The design and quality of the amplifier it’s self is far better than I could have anticipated for the price. Will likley build another one here soon enough so I have a backup. I think the sound quality is good and clear but I’m also not super snobby about having bumping bass and the best speakers money can buy. This simply works well and now I have an excuse to use any speakers I can get my hands on.

Sound is very clean, crisp, easy and simple to install. Connects to my phone with Bluetooth, simple, vol can be adjusted using the phone or at the Bluetooth amplifier itself. It’s small, takes up minimal space. I’m using it to replace a radio that didn’t have Bluetooth, in my Sauna, Will see how well it handles the extreme high heat, but so far works beautifully, should be able to keep hatch closed and it be ok, if to hot, will route wires down close to the floor. Will update this review in a few month. So far good value.

Firstly, I am an audiophile so I know my amps ( have Class A, AB, SET, D, etc. ). This little thing is fine for what it is and the rated power. Before you start, you need, nay require, a more robust power supply. 24 VDC 5 AMP minimum. Actually that is all it needs. I am using this with a single Anthony Gallo Nucleus A'Diva speaker. Yes a 5 Inch Sphere. Only one. I am using it for Bluetooth because most Bluetooth speakers out there are crap. I don't usually listen to Bluetooth. Only on travel ( generally overseas ) or when visiting relatives. This little amp with the upgraded power supply and the Gallo Speakers ... the best Single Channel Bluetooth you can get. Not battery operated, true. But there is power wherever I go on travel and if needed you can get a 110v battery power supply. Working on that. But not sure I want to lug even more weight. Anyway it works and does it's job quite well. Damm, it is the smallest component of my Bluetooth rig !

First the good. This is an amazingly small amplifier with a good quality volume knob, good quality speaker inputs, and the bluetooth synched flawlessly. I did not have bluetooth range problems mentioned by others. Now for the bad. My expectations were quite low regarding sound quality given the price, but this did not meet even those low expectations. The sound quality is simply very poor. I connected this to multiple pairs of speakers, ranging from cheap computer speakers, to $1000 Polk Audio bookshelf speakers, to $30,000 Canton Audio floor speakers. In all cases, the bass was anemic and distorted, voices jumbled, and overall quality very muddy. Compared to another tiny class T amp -- the ORB Audio Mini T -- this F900 amp is a total joke sound quality wise. I know, the ORB Audio Mini-T costs a lot more, but the comparison is remarkable. And now for the ugly -- and the reason for the 1 star review. Once again, of course I did not expect this to actually be a 100w amp. The first hint was that it is shipped with a "60 watt" power supply (more on this later). Nearly all amplifier manufacturers lie about output. If you have ever heard an honest 100 watt amp connected to fairly efficient speakers at high volume, you will understand that 100w of audio output is practically deafening. In other words, most consumers think they need hundreds of watts of output, when most need about 20-30w of clean output for anything other than a nightclub. But I digress. The "100 watt" amp being reviewed here uses less than 9 watts at full volume. I tested it with AC adaptors and with 12v and 24v DC power sources, and I could never get it to pull more than 0.75A @ 12v, or around 8 watts. It sounded horrible at those volume levels, by the way. In other words, the 100 watt specification is overstated by more than 1000%. This is a 4.5w x 4.5w amplifier, plain and simply. So why ship a 9w amp with a 60w power supply, given that a 60w power supply costs more than a 12w power supply? That is a trick question, because the manufacturer did not ship this with a 60w power supply. The power supply is labeled as providing 60w, but it actually provides much less. Based on some quick testing, it seems unstable at more than 2A, or 24w. Yet another lie from our Chinese friends behind this product. Do yourself a favor, spend a little more and get a Orb Audio Mini T or even a SMSL SA50. If you need bluetooth, get a $10 bluetooth receiver. Either amp is in a whole different league than this little piece of junk. You have been warned.

GREAT PRODUCT, GOOD QUALITY AT ALL (.)

I wasn't expecting much for this tiny device. But I was surprised it could drive a pair of 100W speakers with just a 19V 4A laptop charger (I did not use the included power adapter), of course to just maybe half loudness. It fits perfectly for my office use where I need clarity for teleconferencing, music, at the near field and not at loud noise levels. I can not detect any hissing, static, or weird noises from my speakers from using this device, but I have not stress-tested it at max power yet. Music just sounds nice coming out of this setup, not any lesser than another setup I have using a Sonos Connect:Amp.

Excelente opción como amplificador miniatura, tiene bastante potencia out of the box. En el vídeo que les muestro está al 40% y se escucha bastante, lo uso para oficina, obviamente debe ir con unas buenas bocinas y especificacion de DB decente, estás bocinas son de 90 y son de 8ohms@120watts. Les va a fascinar.

Excelente producto, lo conecte a dos marcas diferentes de bocinas y sin problema las levanta (60W IEC-120W PEAK).

Completely blown away by this little amp. It's unbelievable to see a tiny form factor amp deliver sound of a hifi big amp. I was able to setup in no time. Tested with my Wharfedale tower 6 ohm speakers. Sound is really lound and punchy. No humming, No hissing. Quick to connect to Bluetooth. Overall well pleased by the purchase. Truly hope this amp lasts long.
