## 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.
