Q：Why can't I find the Bluetooth pairing name?
A
：
The machine design considers energy saving and environmental
protection. To use Bluetooth, you must switch to the Bluetooth
input mode to search for pairing.
Q：Why does the speaker have a loud buzzing sound after I plug in the
input cable and do not connect the playback source?
A
：
When the unshielded signal line is used without load, interference
signals will enter the amplifier for amplification. If you hate this
sound, it is recommended that you replace the shielded signal line
or unplug the signal line.
Q：Can the 6.35mm headphone output
interface be connected to a microphone?
A
：No, the headphone jack is a signal output interface, not an input interface.
Q：Why is there no sound when the PC-USB is connected to the PC?
A
：First, follow the PC-USB operation steps to confirm whether digital playback
output is selected. If there is still no sound, you can restart the computer and
repeat the operation again.
Q：Why is there no sound from the RCA analog output after all my cables are
plugged in?
A
：At this time, you have to check whether the headphone output detection mode
is set (plug the headphone and automatically disconnect the RCA output). If so,
unplug the earphone, adapter or set the RCA and earphone synchronous
output mode.
