Q & A
Q All my wires are connected_ Why Is there no sound?
- Check whether the machine is turned on and whether it has switched to the corresponding input channel.
- .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?
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?
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 stageis also turned up to the maximum, which
is easy to distort. At this time, you just need to turndown the volume of the
front stage o r t he rear stage.
Q Why is there a lot of electrical noise from the horn?
If you are not using the original standard power supply, please replace the
power supply andtest 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 playthe audio source?
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.
