Gebruikt om usb audio uit een raspberry pi te voeren aan 2 Kef eitjes op het bureau, links en rechts van de monitor. Hoge kwaliteit muziek tijdens het werk.

Versterkertje doet wat het moet kan op best redelijk volume versterker alleen het Bluetooth signaal wordt niet echt goed opgepakt heeft een klein bereik

Werkt gewoon niet, doet niets. Pc herkent het apparaat niet.

It worked ok for me to power 50W bass shakers. But I do not think it is really a 100W amp, no way! Also built quality is not up to a 50 euros product. Due to the lower price point during black Friday, I decided to keep them.

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.

Setting up front and rear bass shakers for the racing rig, so 4 channels required. As I bought the DS200i shakers, which are 100 Watts, I bought one of these amps and one NobSound, which is the recommendation on all of the youtube videos.I wasn't sure if the USB connection would act as it's own sound card, which was the only reason I didn't order 2. But pleased to say it does, no drivers needed, just appears in the audio device list for Windows.The unit is the same profile as the NobSound, but slightly longer... All the buttons seem to be good quality and it is as simple as plug and play. Note - I have not used the bluetooth connectivty, only USB.In terms of power... I connected this amp to two of the transducers and the NobSound to the other two. It is a massive difference, this amp really packs a punch, whereas the NobSound was about 30-40% of this. I guess this is not surprising, the power supply provided with this unit was 24V and 5A = 120 Watts the one supplied with the NobSound is 12V and 5A = 60 Watts. The NobSound does only declare 50W per channel.In terms of price the NobSound was £5 more that this unit... So, I will be boxing it back up, returning it to get another of these!!Great value and recommended!

Tutto ok

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.

Zaskakująco dobra jakość dźwięku, jak na takie maleństwo. Przy dobrych głośnikach wysokie tony są nieco natarczywe, ostre, ale nie ma tragedii. Średnica całkiem bliska, dość żywiołowa, choć oczywiście z cyfrowym nalotem. Bas niezbyt szeroki, może trochę zbyt krótki, ale nie jest dudniący, całkiem silny. Dźwięk ma trochę mało przestrzeni, ale nie ma co marudzić.Zaskoczyły mnie 2 rzeczy - po pierwsze - jakość z bluetooth jest lepsza, niż po kablu. Po drugie - dźwięk podany przez usb jest bardzo cichy, niemożliwy do słuchania. Nie wiem, czy to cecha, czy wada.W moim przypadku jest to sprzęt grający... w stolarni ;) Ale całkiem przyjemnie jest oderwać się od pracy i posłuchać czegoś ostrego.Jeszcze jedno - lepiej sobie radzi z elektroniką, niż ze starym, gitarowym rokiem.
