Q: All my cables are connected, but there is no sound output?
A: 1. Check whether the screen lights up. If the screen does not light up, briefly press the
ON/OFF key to start the machine.
2. Check the screen volume value. If the volume value is too low, turn the encoder knob or
the remote control to the right to increase the volume.
3. If the above two points are normal, check whether the playback device of the input sound
source is paused, muted, or the volume is at the minimum.
Q: Why is the sound distorted?
A: The input level may be too large. If the volume of the sound source equipment is adjusted
to the maximum, and the volume of the machine is also adjusted to the maximum, it is easy
to be distorted. At this time, turn down the volume of the sound source input device or
machine.
Q: Why does the volume of the machine remain the same, but the sound
level is different when connecting to different audio sources (for example,
connect a CD first, then a mobile phone)?
A: The amplitude of electrical signals output by different playback devices is different. For
example, mobile phones are usually 0.35V, while CDs are 1V. The natural sound size is different.
Q: Why does the horn make a loud current sound?
A: If you use a power supply other than the original standard, please replace the power supply
before testing. Many power sources on the market have large interference coefficient of the
text wave, which will cause a large current sound.
Q: Why does the speaker make a loud buzzing sound when I plug in the input
cable and do not connect the playback source?
A: When the unshielded signal line is unloaded, the interference signal will enter the power
amplifier for amplification. It is recommended to replace it with shielded signal wire or unplug
the signal wire.
Q: Why can't I find the Bluetooth pairing name?
A: Since power consumption is considered in the design of this machine, Bluetooth does not
work when other channels are used. You must switch to Bluetooth input mode to search for
pairing.
Q: Can I change the tube directly without turning off the power?
A: No, because the machine works under high voltage, the hot plug electronic tube may burn
out and damage the machine.
Q: Why does Bluetooth sound intermittent?
A: When using Bluetooth to test the distance, it is normal that the sound is not stuck or
disconnected (without any obstacles) within 10 meters.(Note: The router will interfere with
the Bluetooth signal. Don't get too close!)
