## Questions & Answers

**Q: The power amplifier is connected correctly, why is there noise such as electric current?**
A: 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.

**Q: Why only one channel work ? Is it defective?**
A: 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?

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

**Q: Can you connect two devices with bluetooth?**
A: 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.

**Q: How to connect to a bluetooth speaker?**
A: 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.

### ⭐⭐⭐⭐⭐ good tiny amplifier
*by G***N on December 29, 2025*

excellent value, quite flexible, good sound, smooth controls, well-designed

### ⭐⭐⭐⭐⭐ Love it
*by B***N on January 11, 2026*

Love it works great and is loud and clear through speakers and the Bluetooth function works really great as well

### ⭐⭐⭐⭐ Great little 4 ohm option.
*by A***S on December 7, 2025*

My first item would not turn on. The power connection was loose in the unit. Easy return with Amazon. The unit itself is small, but put together rather well with decent quality on the chassis (other than the first one had a bad connection internally). The remote works well, even though it is very small. Connected easily to my computer as well as my phone. You can control the total amount of volume with the knob on the unit, and refine it within that setting with the remote. There is a slight hiss when first turning on the unit, but it is not noticeable once you start playing sound through the speakers. I had found a really clean set of Bose 6.2 speakers at a flea market, and this little unit makes them sound like new. The radio channels are a little tricky to get a set station programmed, but overall, I am not disappointed.
