FQA： Q: All my wires are connected. Why is there no sound? A: 1. Check whether the machine is turned on and whether it has switched to the corresponding input channel. 2. Check whether the back-end connection is correct and whether the volume is in the minimum state. 3. If all the above are normal, check whether the input playback device is silent, paused, or the volume is at its minimum. Q: Why can't I search for bluetooth pairing names? A: Due to the design of this machine, bluetooth does not work when using other channels for input. You just need to switch the input to Bluetooth mode. Q: Why does the sound break A: Although this product is the front stage of DAC, it also has the function of amplification. If the volume of the rear stage device is turned up to the maximum, the volume of the front stage is also turned up to the maximum, which is easy to distort. At this time, you just need to turn down the volume of the front stage or the rear stage. Q: Why is there a lot of electrical noise from the horn? A: If you are not using the original standard power supply, please replace the power supply and test again.Many power supply ripple interference factor is large will cause a lot of current sound. Q: Why does the speaker make a loud buzzing sound when I plug in the input cord and don't play the audio source? A: when the signal line without shield is used, the interference signal will enter the power amplifier for amplification. Replacing the signal line with shield can effectively solve the interference sound, or unplug the signal line.
