Q：Why is it normal when playing PCM music, but there is noise when
playing DSD music?
A
：
This is normal. You need to right-click the computer
'
s speaker
icon,
open the music synthesizer, and turn on the device's
speaker to the
maximum
when playing PCM music format (not when playing DSD).
To play DSD, you need to turn on the computer's volume to the
maximum, otherwise it will affect the DSD output
Q：Why is the sound broken?
A
：
Although this product is a DAC, it can also be used as a front-end
product, which has an amplifying effect. If the volume of the back-end
device and the front-end device is adjusted to the maximum in the same
time, it is easy to be distorted. At this time, you only need to lower the
volume of the front-end device or the back-end device.
Q：Why is there a loud current noise from the speaker?
A
：
If you are not using the standard power supply of the original factory,
please replace the power supply before testing. Many power supplies
on the market have large wave interference coefficients, which will
cause large current noise.
Q
： All my cables are connected, but there is no sound output?
A
：
Check whether the display is on. The display is
still off after pressing
the power button. At this time, you can find an adapter with the same
voltage output (must be DC12V)
to test to determine
whether
the machine
is faulty or the power adapter is faulty. If the display is on, check whether
the corresponding input signal is selected correctly.If there is no sound
after checking the above two points, check the digital volume status of
the display. If the volume is too low, please press the volume up
button
or the remote control to increase the volume.If the above two points are
normal, check whether the playback device of the input audio source is
paused, muted, or the volume is at the minimum state.
