Fosi Audio ZK-1002D Mini Bluetooth Amplifier HiFi Stereo Wireless Audio Receiver Compact Power Amp 100W *2 dual channel Class D with AUX USB Inputs for Passive Speakers

Works great. So small and yet the sound fills the room. I'm using the usb as input

I bought this to use with bass shakers on my racing sim rig. It connects directly to the pc via usb, no rca cables are required as it has a built in sound card. Using sim hub it was a breeze to set up and works well. I have it set to about 30% volume with two DA bst-1’s connected. It’s ideal for this application and comes recommended.

I loved the sound and quality it delivered. Very easy to install, I received the product in perfect condition and on time.

I love it. It is new best bt friend. Using it as my new goto bt audio for listening for spotify. It has much Better crisp clear sound than my other bt systems ranging from 50 to 120£ and it is loud enough for my personal listening. I have not even taken the sound over 40% of the volume. I will try it with an LP player soon as that was my primary usecase with a RCA to stereo cable. It works. It could use a phono pre amp. But it works great as is for me.

Brilliant kit

All was good to begin with, sound is decent for the size with my 6.5" ceiling speakers. Bluetooth works well (although the voice is quite annoying). I used mine with a 3.5mm cable and an old Amazon Echo. The trouble started after around 6 months in. Anytime there is silence it makes a loud buzzing pop sound! Doesn't matter if it's on bluetooth, 3.5mm aux or any of the different source devices I plugged in. It happens when you aren't using it and when there is a very quiet/silent part or gap in songs. It's so frequent I have stopped using it. Will probably use one of my old AV receivers for the time being, but it's a terrible waste of electricity just for some background music!

Well what a great product. Easy to connect and it accepts a range of voltage so good for car, rv, boat or mains. Straightforward connection with Bluetooth. Great sound too. As you can tell I am delighted, the boats speakers handle the power far better than the old car radio.

This Amplifier is a good piece of audio hardware. It has Bluetooth connectivity plus auxiliary input and micro USB audio interface. Bear in mind you will need a audio in to RCA input to connect to another DAC. Bear in mind you need to lower the volume connected DAC to avoid distortion in bass. (Passive Amplifier connected via Headphone DAC Amp)

Fosi markasının başka bir modelini kullanan biri olarak nispeten küçük olan bu modeline de bir şans vermek istedim, JBL Control One hoparlörlerimi çok rahatlıkla sürmekte ve gayet temiz bir ses vermekte. Herhangi bir dip ses vs. yok.

外観はかなり良いのですが、 はずれを引いたのか、購入後３週間で左側から音が出なくなりました。 返品可能期間内なので、返品します。

I have an old pair (2004) of Bose outdoor speakers. They just sounded like the radio station was never tuned in. In the back on my mind, I thought the crappy AM/FM/CD player I used wasn't putting out enough power. On a whim, I purchased this FOSI wireless power amplifier. I have never even heard of such a thing before. The hook-up was a snap-plug it in, attach the speaker wires-BOOM, you're done. Look for FOSI under on your cell phone Bluetooth and you are good to go. total installation was under 3 minutes, but the sound coming out of my old Bose speakers is just amazing. I am so happy, I purchased a second unit for my daughter's home. FOSI makes really high-quality, great sounding products.

Ich habe grade schon den zweiten Fosi Audio Verstärker gekauft und mit alten Boxen verbunden. Wie schon mit meinen passiven Lautsprechern (zweiadrige Kabel, rot und schwarz) von Sony hat das verbinden mit den Bi-Wiring Lausprechern (4 zweiadrige Kabel) von Panasonic super funktioniert. Man muss keine extra Stecker wie Bananenstecker kaufen, sondern kann die abisolierten Kupferkabel (mit verdrillten Kupferlitzen) direkt in die Schraubklemmen stecken. Der Sound bleibt auch bei hoher Lautstärke sehr klar und die Bluetooth Verbindung wird in Sekunden hergestellt. Der Verstärker funktioniert einwandfrei seit einem Monat. Ich finde so ein kleiner Bluetooth Verstärker ist eine tolle Möglichkeit für wenig Geld eine alte Stereo zu ersetzten!

Używam go od jakiegoś czasu, jest na prawdę mocny jak na swoje małe gabaryty, jakość i estetyka wykonania na wysokim poziomie, mamy też bluetooth więc z łatwością połączymy się czy to z telefonem czy z komputerem, używam go do simrecingu jako wzmacniacz na bass shaker 2x50w I to naprawdę działa dobrze, jest moc! Szybkość przekazywania dźwięku, dynamika jest na bardzo dobrym poziomie, używam go po kablu USB, mogło by to być USB typu C, mam sporo kabli ale tego musiałem poszukać dość długo, polecam również firmę Fosi Audio! Kontakt z nimi jest na prawdę doskonały, miły i odpowiedzą na każde pytanie! :)
