WOOPKER AK45 Pro Amplifier Home Audio Stereo Receivers with Bluetooth 5.0,Max 400W,2.0 Channel Stereo Amplifier System for Home Theater Speakers, Karaoke,Garage,Home Amp with USB,SD,RCA,2 MIC in

I want to start this off by saying I know VERY little about how this actually works lol. The sound quality of this when connected to speakers is wonderful and very clear. It is very simple and easy to connect to my smaller speakers, there aren’t a ton of features but enough to customize your sound experience. The light colors can not be changed sadly, I’d have liked to be able to do that. It provides more than enough power to my small speakers for them to be used with no issue and it is instantly responsive. The machine is very lightweight but the buttons and knobs feel sturdy. I’d recommend this as an inexpensive starter piece of sound equipment or if you’re like me and just want to have some speakers to listen to music casually/rain sounds on at night to make it realistic lol.

I needed an amplifier for my 1990s Denon turntable with FM reception. I tried the AK-35 and the turntable didn't work at all. Then I tried this AK-45 and the turntable worked but I had to put the volume at full blast and I could barely hear it. After researching the problem, I learned that a Preamp is required to get the sound to work properly. I found Pyle Ultra Compact Phono Preamp Model PP444 https://www.amazon.com/dp/B004HJ1TTQ?ref=ppx_yo2ov_dt_b_fed_asin_title The Preamp was easy to hook up and voila! I have sound working with my turntable! Volume is perfect for my needs. I use it in my office. I only gave it a 4 star because it wasn't easy to tune into my favorite radio station 104.3. Scan would keep passing it up and I didn't know how to make it stop where I needed it. I couldn't find where you can just input the station I wanted. The directions didn't help. It took several tried and I finally got it to work but I'm not sure what I did. I like that I can turn it off with the remote and all I have to do is change to FM mode and it remembers the last station and I just leave it there. It's looks good and I appreciate the compact size. UPDATE: 5 Star - FM receiver, I can enter the station number and it goes directly to it.

Needed a small blue tooth amp for my office. Works well driving some old Yamaha speakers.

I fully expected to return this thing when I saw how tiny it was .I bought this for my garage I have a pair of really old 3 way speakers up on shelves with 12” woofers. No way this tiny little thing was going to power them, but I hooked them up anyway and was shocked! I have owned a lot of audio equipment in my time and surprisingly this one is way up top 5 at least. Not only does it drive my old speakers the clarity is amazing . The mid range and vocals are perfect,the bass is plenty adequate, and there is more treble than you’re going to need. The Bluetooth connects quickly and easy . I am amazed by this little unit!

It's economical and decent, but the bass isn't very powerful; I feel it lacks power. I have a good Sound Blaster Xtrame Audio sound card, and I adjusted the equalization and sound effects to get the best sound quality. Without the effects activated, it doesn't sound good. This device isn't for demanding audio users, but it's adequate. Don't expect it to sound like a high-quality sound system.

Great value for the price. 🌟🌟🌟🌟🌟 This device provides loud clear sound 🔊 I purchased this to power my living room television’s tower speaker system. All that was needed was to connect the speakers to the amplifier and then connect the audio output on the television to the audio input on this amplifier. It’s definitely loud enough for watching football and movies.🔊 I haven’t even turned it up much louder than 25% and clear undistorted sound fills the room. I also tried listening to some music via USB, and again it’s loud and the music doesn’t distort, with my speakers which can handle the amplifier’s wattage. You could easily use this amplifier for an inexpensive and effective home stereo system. Just get some decent speakers, and you are good to go.🔊 *The only slight and insignificant drawback is with the USB you cannot skip from folder (album) to folder (album), you need to skip from track (song) to track (song) or enter the specific track’s (song’s) number, and even a 16GB USB holds 1000s of MP3s. The easy solution is to just get several USBs and create a playlist of 50-100 songs for each. 💡 Not a huge drawback. Additionally, the artist name, song name, etc. is not visible on the device’s display screen. Again, my opinion, that should not deter anyone from purchasing this amplifier. While listening via USB, I expect most people will recognize the artists, albums etc. that they selected for their USB playlists. I am giving this 5 stars considering it does exactly what I purchased it to do and the value for the price. Focus on the device’s sound quality and volume capability. 🌟🌟🌟🌟🌟 I haven’t tried to connect via Bluetooth or listen to the radio but I expect that works fine. Again, this amplifier is easy to use, loud and produces a clear sound 🎼🎵🎶 Great value for the price 🌟🌟🌟🌟🌟

The aK45 pro is a step up. I initially bought the lower model and got zero response from their customer service so I utilized Amazon’s return policy and just moved up a model. Would be cautious as the customer service seems to be non existent

Because this was small, I thought it wasn’t a great thing to get. Wow! Was I wrong! A great sound in a small package. Hmm! Where have I heard that before?! *wink wink*

Good Product

Das kleine Ding hat es in sich, ist natürlich von High End weit entfernt, aber auf unsere Diele bedient es die alten großen Lautsprecherboxen sehr gut. Der Bass ist nicht so toll, zu stark aufgedreht geht der Verstärker in die Knie. Funktioniert einwandfrei mit Bluetooth oder line in. Radio haben wir nicht getestet, läuft bei uns meist über die ausgemusterte gute alte Echo Dot 3. Wer also laut will und auf viel Bass verzichten kann - Let's Party!

Aber besser, als erwartet. Vor allem, wenn man sich vorher von selbsternannten YT-"Exbäärde" hat verunsichern lassen. Das Ding kostet keine 30€! Dafür ist der Klang absolut okay und die erreichbare Lautstärke für alles diesseits "Kellerparty" ausreichend. Außerdem - und das ist ja leider heutzutage eine dedizierte Erwähnung wert - FUNKTIONIERT das Ding! Einschließlich Fernbedienung und Bluetooth. Befeuert bei mir in der Chill- and Fitness-Lounge das Heimkino und liefert ggf. Motivationsmucke per BT.

Very cool

Perfekt
