  • Please check whether there is current sound when no load. And confirm that the surrounding current signals will not cause interference. Please make sure all the cable completely pushed into the device, incompletely connections will create distorted.

  • Since the amplifier is not used alone, it needs to be used together with other electronic equipment, so it needs to be ruled out one by one! Are the positive and negative wires connected to the speaker connected together?

  • Make sure there are no obstacles (especially metals) blocking the signal. Turn off the power amplifier, disconnect and clear the connection of the Bluetooth transmitting device, and try to reconnect.

  • No, connecting two at the same time will cause the audio stream to be disrupted. It can only be disconnected and then connected to other devices.

  • The Bluetooth speaker is a Bluetooth receiver, which is the same as the Bluetooth function of the power amplifier, and the Bluetooth speaker already has a small power amplifier, which may cause burn-in after being amplified by other power amplifiers.

For the money this is a great itemHas everything built in its worth price . Only thing to know is you will need a phono preamp if you intend to use an old school record player

Not going to say this is a high end amplifier, it isn't. It IS 300watts of amplification and will drive most all bookshelf type speakers cleanly. Speakers make or break the amplifier, not the other way around, so pair it with good speakers and you will be pleased.

It's a great unit that works wonderful with my existing setup that needed an amplifier upgrade and the connectivity is great. Has an mp3 usb port if you are into that stuff(all my music is flac) and Bluetooth has great range. A great feature is the usb charger port! You don't lose a plug using this thing and it's great! The weakness of the unit is it's controller, it's hit or miss

I needed this to be able to connect my speakers I got from Goodwill to my turn table. It worked awesome especially for the price point. Sound quality is wonderful from my speakers and the system does its job properly with managing the bass and treble. I also appreciate the Bluetooth capability and the fact that it comes with a little remote.

I like the look and the size that's the main reason I chose this one over the others. Bluetooth works great, MP3 USB works great, FM signal pick up is good.The disappointment is the line input. It is very low and can only use 3.5 jack or RCA not both. I putting in my MP3 player on the line in and it's very low. You have to turn up the volume. Then if you change the mode to Bluetooth or FM the volume is very loud. Very annoying It's two different sound levels for the input and the FM and Bluetooth. The sound quality is good but the amplification is not there.I bought this cuz I wanted something small to put on my workbench to test audio equipment for reselling. If I would have bought this for personal use, I would be very disappointment with the input line.Update: stopped working so I opened up the case and found bad soldering joints on on/off/volume knob. Reworked the solder joint and it worked again. Bad quality control not sure, if the soldering was cold joints or something is heating up and making joints melt loose. I lowered my rating from 4 stars to three stars. Only because I know how to solder and I was able to fix it. Otherwise I would have given it one star. If anybody else has the same problem, just rework the solder joints under the volume knob

The Sunbuck is small - which I want - and powerful enough to drive the bookshelf speakers in my office. The Bluetooth receiver works well, as do the line inputs I use for a Roku/TV/DVD combination. I have an old iPhone 6 (that isn't a phone any more) dedicated to music complete with my playlists. It's essentially a slightly updated iPod that also doubles as a clock, but the Bluetooth transmitter works just fine.The quirk in this receiver is that the built-in preamp is controlled by the remote That works for everything except the radio receiver, which (probably because it's just a commercial chip designed for something else) has its own preamp, which feeds its already amplified output to the system preamp. That can cause a loud surprise if you happen to switch to or even past the FM mode after using the remote to control volume with the power amp turned up with the knob. Not a deal killer, as long as you're aware of the behavior.Given the price, it's still a good deal for a small integrated receiver.

🌟🌟🌟🌟🌟 Hidden Gem Amplifier That Makes Budget Speakers Sing!Was skeptical about hooking up this budget amplifier to my Facebook Marketplace find (Sony SS-CS5 speakers). As someone who loves good sound but keeps things affordable, I had my doubts - would it be all static and distortion? Could this humble amp actually drive these speakers properly?Let me tell you - I was BLOWN AWAY. Hooked it straight from my computer's audio out to the amp, then to the speakers, and the result? Absolutely incredible. It made my old PreSonus 3.5 monitors sound like toys in comparison. The highs are crystal clear, the lows are rich and full, and there's not a hint of the distortion I was worried about.While I wouldn't call myself an audiophile, this little amp makes me feel like one. The sound quality you get for the price is just ridiculous. If you're like me - someone who loves great sound but likes to keep things budget-friendly - this amp is a no-brainer.Pros:Punches way above its price pointZero distortion issuesDrives speakers beautifullyClean, clear sound across all frequenciesSimple setup with computer audioDon't let the modest price tag fool you - this amp is a serious performer. Perfect for budget-conscious music lovers who want premium sound without the premium price tag.
