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 is the sound distorted?
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 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: 1. If you are not using the original standard power supply, please replace the power supply
and test again.Many power supplies in the market have interference, which will cause
current sound.
Q: Why does the horn emit a loud electrical current sound or buzzing sound?
A: 1. Check if the machine has started and if the indicator light is on.
2. Is the selection of mono/stereo mode and the connection of the speaker interface correct.
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: All my cables are connected, but there is no sound output?
