Q: Why does the amplifier stop working after a period of time? Then after a period of
time with no sound, it works again ?
A: The amplifier is probably overheating. It is protected, and the output power may have
exceeded the designed power, best to lower the volume a little and then try again.
Q: why does the volume of the amplifier 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 is the sound of the power amplifier poor 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 devices that also need to know each other.
Sounds usually get better after working on new amplifiers and speakers for more than ten
hours.
