The power amplifier is connected correctly, why is there noise such as electric current?

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.

Why only one channel work ? Is it defective?

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?

If you find that the Bluetooth connection is unstable, you can try the following steps to solve it.

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.

Can you connect two devices with bluetooth?

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.

How to connect to a bluetooth speaker?

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.

This Sunbuck Mini Amplifier is a perfect fit for my setup! Paired with a USB Bluetooth dongle on my KVM switch, it drives audio from my Windows 11 PC and MacBook Pro to desktop speakers via a Bluetooth amp. The 300Wx2 output delivers clear, punchy sound with no distortion, even at higher volumes. It’s super compact—barely bigger than my hand—yet handles RCA, USB, FM, and AUX inputs like a champ. Setup was a breeze, and it switches seamlessly between devices. For its size and price, this little amp packs a serious punch—ideal for tech lovers juggling multiple systems!

🌟🌟🌟🌟🌟 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 point Zero distortion issues Drives speakers beautifully Clean, clear sound across all frequencies Simple setup with computer audio Don'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.
