Good Product

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.

Endlich kann ich meine alten Lautsprecher wieder hören. Gute Leistung für den Preis. Bass und Höhen regeln deutlich, mit Bluetooth Radio und Line in sehr gut ausgestattet.

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!

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.

Perfect for what I needed - backyard & garage music with radio and bluetooth. BT range is more than enough at 30-35 ft. Sound is outstanding for such a small unit. Only issue is radio channel surfing is annoying and appears can only be done with the remote. For the price - so far it’s a no brainer.
