largest, it is easy to be distorted. In this case, you only need to turn down the
volume of the previous or subsequent stage.
Q: Why do loudspeakers make a lot of electric noise?
A: if you are not using the original factory standard power supply, please replace
the power supply before testing.Many power supply in the market have large
interference coefficient, which will cause a lot of current sound.
Q: Why is the speaker noisy when I plug in the input cable but no sound source is
connected?
A: If an unshielded signal line is used, an interfering signal will enter the power
amplifier. If you hate this sound, it is recommended that you use a shielded signal
cable or unplug the signal cable.
Q: Why does the amplifier stop working after a period of time? After a period of
time off, it was working again
A: Normally in this case, the amplifier is overheating protected, and the output
power may have exceeded the designed power, so you can lower the volume a little
and then try again.
Q: why does the volume of the machine stay the same, while the sound of different
audio sources (such as CDS and mobile phones) is different?
A: Different types of audio equipment have different output frequency ranges. The
mobile phone is usually 0.35mV and the CD is 1V. The signal output frequency of the
sound source will directly affect the volume.
Q: Why the sound of the power amplifier is not very good at the beginning, the
high frequency is not clear, but after working for 8 hours the sound is normal?
A: Speakers and amplifiers are a very sensitive device that also needs to know each
other. Sounds usually get better after working on new amplifiers and speakers for
more than ten hours.
