Great reception for the blue tooth- good value for the money.
est parfaite
Ottimo,nulla da dire,le specifiche tecniche sono esattamente quelle descritte,non c’ nessun problema
Amazing power and easy Bluetooth connectivity. Works great with a passive sub woofer to give 2.1 sound depth. Hookup via banana plugs or screw in wire terminals and rca inputs or just simply connect Bluetooth via your phone or iPad.
Value for money and has channel and volume for subwoofe
I am so impressed with this small powerhouse, I added a subwoofer and cannot believe how good it sounds. My backyard is a musical paradise.
Het produkt voldoet volledig aan mijn verwachtingen .Het werkt zeer goed. Ik heb dit specifiek produkt alleen bij Amazon gevonde
It was only as a short term replacement after my Harmon Kardon amp went in for repairs, but I won’t be going back. The space it saves on the shelf alone makes it worth it.
Got this prior to moving out of state, worked good for about a month then stopped powering on. Worked with customer service, they sent a new power supply within a week and back up and running. Awesome customer support and product!
Its just a quality amp. watch any of the jillions of videos about it. its just plain good. why mess around on bargain brand amps? this is clearly the answer.
Works great with a pair of Polk Audio speakers on the boat dock. Connects quickly and has a great range.
Good for its price and position. Using with MICCA MB42X passive speakers as PC speakers
Amplificateur bien construit et trs petit.
Permet de brancher 2 enceintes 50w et 1 caisson de basse de 100w. Pour le moment rien dire!
Le bluetooth marche correctement. Il manquerait une tlcommande pour allumer et teindre distance ainsi qu’un permutateur pour changer entre entre aux et bluetooth
Habe das Produkt selber fr den Partykeller gekauft. Habe 2 Magnat Boxen angeschlossen die doch gute Lautstrke auf max. Herausbringen.
Verbindung per Bluetooth super und stabil.
Koppeln ohne Code einfach mglich.
Lautstrke und Frequenzeunstellung lsst sich gut regeln und die Drehregler machen einen sehr hochwertigen Eindruck. Nicht wackelig und gutes haptisches Empfinden.
Fr kleine Anwendungen wie in meinem Fall voll ausreichend.
J’ai d retourner cet article une premire fois, car on. entendait un HISS constant indpendamment du volume. Aussi l’ampli tait particulirement chaud. Heureusement qu’Amazon offre un service de retour et de remboursement des articles qui est efficace, mais c’est quand mme une perte de temps. Je n’ai pas diagnostiqu la source du problme. Il y a un problme de contrle de la qualit, mme si l’tiquette QC tait appose.
La deuxime fois que j’ai achet ce produit, le niveau de hiss tait raisonnable. J’ai compar avec un ampli TEAC et c’tait quivalent. J’aime bien le son de cet appareil. Je n’ai pas fait de test en profondeur par contre. J’ai branch des Hauts-parleurs trs quelconque 2x DAYTON en stro et un vieil HP qui tranait dans la cave qui m’a servi de SUBWOOFER ici et a a renforc les basses de manire importante. J’ai aussi branch un troisime Haut-Parleur hors phase en arrire : le positif du canal gauche et le ngatif du canal de droite ce qui ajoute un peu d’espace l’ensemble, le tout avec des HP de qualit tout juste OK et le rsultat tait impressionnant. Donc je suis satisfait. Le tout est install dans ma salle de bain car j’aime bien commencer ma journe en musique.
Le Bluetooth fonctionne trs bien avec mon iPhone 8 plus.
Cependant, la source utilise pourrait tre problmatique. J’ai fait jou Sgt Pepper’s des Beatles depuis Amazon Music version gratuite avec un abonnement prime et c’tait carrment infecte. Je suppose que la compression du son est exagre. Cependant des enregistrements qui venaient de ma collection iTunes taient toujours trs corrects. Je n’ai pas pouss plus loin l’investigation par ailleurs. Je vous suggre d’essayer diverses sources lorsque vous tester cet appareil.
En conclusion je mets 4 toiles parce que j’ai d retourner un premier achat.
Dans l’ensemble je sus quand mme satisfai
This is a great amp. Survives Phoenix in all elements.
Have currently connected to 50W Sony Bass Reflex 3Way Speakers, volumn is good, control knobs quality good, is as advertised. Bluetooth connection superior, immediate from paired tablet, phone and computer. Wish there was a balance contol between speakers.
Echt tolles teil ,guter Klang verstrkt echt irre gut, ein aus Schalter gut zu bedienen, Bluetooth gut ,und was auch sehr toll ist ,ist das du sowohl aktiv alsauch passiv subwoofer anschlieen kanns
Hooked up 2 monitors and a 10″ JBL car sub to it. Sounds great. Just what I needed
Was important to play music quite and have good quality sound. I have 100W 8ohm speakers. Plays better than from my original sony theater amplifier which i hate.
Didn’t really think this little amp would work, but it is awesome!! I had 2 outdoor Yamaha outdoor speakers when I bought my house. I ordered the RCA jacks to hook up the speakers and turned it on. It powered them perfectly and they are loud! Very impressed!
Molt bona qualitat de so per un amplificador tan petit. Bon control del subwoofer. Recomanable per la bona relaci qualitat preu.
5 Sterne fr diesen Verstrker.
Angeschlossen: 2x Canton Boxen von 1990; 1x Plattenspieler von 1980 oder im Wechsel Technics Tape Deck/ CD-Player von 1990 und 1995 und per Bluetooth ein MacBook Air M1 2021 .
Ein kostengnstiger, leistungsstarker, kleiner/ platzsparender Receiver zu einem super Preis ( 99,90 inkl. Rabatt bei meinem Kauf ) fr den “normalen” Gebrauch alter Gerte oder fr Audio Einsteiger perfekt.
Ich bin sehr begeistert.
Bought this to hook up some outdoor speakers for Bluetooth streaming. Set it up indoors to test it out sweet! Bluetooth connection is straight forward and comfortably drives a pair of Bose outdoor speakers. Happy with i
I got this to replace my Topping MX3, and oh what a great little amp. I can get my two Polk T15s, and 10″ sub above 100db with zero issues, or I can run them as quite as I’d like without losing clarity at either end. I had worried about interference, but even with a CRT running inches from the amp I’ve had no issues.
What I really liked about this is the sheer speed and simplicity of the bluetooth connection. Go to your smart phone’s setting and connect to bluetooth to ‘Fosi Audio’. That’s it! No searching and installing of an app, setting up an account & password and providing an email address, name, postcode etc so that they can spam you later. Bose, Sonos, etc I hope you guys are paying attention.
Once connected, which is very fast, the small led turns blue. The sound quality is amazing and I honestly cannot fault it. I’ve got mine connected to a pair of Monitor Audio Silver 5 and M&K active sub-woofer. Sounds as good as my other amps from well-established hi-fi brands (I.e. NAD, Rotel and Arcam) but FA has the advantage of bluetooth whereas the other do not.
Highly recommended.
Ottimo prodotto, pensavo peggio ed invece si comporta bene , anche con un sub woofer da 500w riesce a gestire abbastanza bene
Consigliato
Mein Ur-alt Verstrker von Universum hat nach ber 20 Jahren den Geist aufgegeben. Jetzt stand ich da und brauchte Ersatz fr die Boxen und so blieb ich nach vielem lesen bei Flosi hngen. Den Ausschlag fr dieses Modell gab der passive Subwoofer Ausgang. Bestellt und am nchsten Tag geliefert,da ich ausversehen cinch anstatt bananenstecker bestellte,schloss ich die Kabel direkt an,was problemlos ging. Da das ganze fr mein laptop gedacht war und ich nur einen kleinen Raum habe,dachte ich wird schon einigermaen werden. Ich schloss es ber meinen Kopfhrerausgang an und spielte das erste Lied ab…und war baff. Das ist absolut geiler Sound und der Bass kommt richtig klasse zur Geltung…! Ich habe 4 Satelittenboxen…je zwei pro Kanal a 100 Watt dran,den Subwoofer passiv. Fr meine Belange kann ich nur sagen…saugeil^^ Ich probierte dann die Bluetooth Variante,was ebenfalls ohne Probleme ging. Es gibt aber einen Unterschied beim Ton,der ist deutlich heller und die Bsse nicht ganz so stark…hab mich dann fr den Kopfhreranschluss entschieden,da man die Bsse so schon bei niedriger Lautsrke gut hrt. Ich habe jetzt keinen Vergleich mit einem grerem Raum,aber wer wie ich eine kleine Ecke hat,fhrt meiner Meinung nach,damit absolut super!
Used to power 5 speak setup – 4 Polk bookshelf speakers and a powered Polk SW. Amazing sound, easy setup, and solves problem of how to power room speakers unobtrusively – without a huge receiver or amp sitting around. Highly reccomnd
Estara bien poder balancear el derecho y el izquierdo. Por lo dems como he dicho robusto y sencillo. Los materiales perfectos y el sonido que es lo que importa, probado con altavoces y sobwofer infinity, genial.
I’ve bought three of these devices, one for my office, one for my home audio and one for my son’s apartment. The sound quality is great and full. Having the adjustments for bass treble and even sub level was well thought out. One set I use with a Pyle zone switch so I can select living room speakers or patio speakers. Nice to have the option for audio input as well as Bluetooth. Very pleased with my purchase.
Bought this to run small computer speakers along with a subwoofer I built. Provides plenty of power for that use and sounds great at high volumes. No clue how this would work with larger speakers, but for my use it is perfect. My only gripe is it does not auto-reconnect if you move too far away when connected to Bluetooth. Built well and does not get hot at all (neigher the power supply or amp itself) and the adjustability of the crossover/volume for the sub lets you blend everything together perfectly.
Using the amp to run some small speakers in the bedroom. Most critical part for me as that there was no background hiss and a smooth frequency response with low distortion, high power was not a consideration as I only listen at low to medium volumes. This amp exceeded my expectations. Plenty of volume for my application, Dead quiet and easily connects to my phone. Very clean sounding without any harshness. Physically solid with a little heft. Knobs don’t have detents which I prefer. More that perfect for my application.
Wow I am amazed at how well this small inexpensive amp works! I have been really dissatisfied with listening to music with my home surround system the Sony STR DH 590. It works fine for tv and movies but the music options are very dull. I ordered this little Fosi amp BTD 30 D and hooked it up to a CD player and it sounds so much better than through the Sony. The subwoofer output is great! Love this new little amp. Now I have the two main front speakers powered with both amps using the Solupeak P2 switch to change between amps. Loving it!
