1. The most common malfunction of power amplifiers is that the
capacitor is broken or the amplifier tube is burned, which is a
problem we encounter when using them, but most of the time, the
equipment itself is unstable.
2. Another thing I have noticed is that some amplifiers may
experience a channel failure with no sound, but the problem is
still with the internal circuit.
3. As for other faults, such as poor contact of the amplifier
volume potentiometer, imbalance of the left and right channels,
frequent protection functions, poor contact of the rear panel
work conversion switch, and signal 3 socket, etc., in short,
amplifiers are a type of electrical equipment that is more prone
to malfunctions in audio systems nowadays.
4. The most common malfunction of a speaker is undoubtedly the
issue with the speaker. It can be said that the most common
malfunction in a sound system is the burning out of the speaker,
which of course has human factors, but most of it is still a
quality issue with the speaker itself.
5. Another common problem with speakers is aging of the wiring
ports and poor contact, especially with speakers that frequently
flow. Generally, sound engineers are unable to repair the
malfunctions of the equipment mentioned above. As I mentioned in
the previous article, sound engineers need to be
"professional". If any amplifier or speaker is
damaged, it is the responsibility of the maintenance engineer.
Our sound engineer's scope of work is to properly match the
sound system and adjust various sounds. This type of malfunction
is usually caused by the speaker's excessive volume, which
leads to the subwoofer being burned out after prolonged use.
This is very normal, friends who like bass believe that the
larger the volume, the better. Some friends can even turn it up
very high, and the volume is also adjusted to over 70%, which is
the easiest way to burn out the bass. Normally, it is
recommended to choose a volume of 30% -50%, and a bass of 30%
-40% is sufficient. Additionally, this situation may also be due
to a broken wire end.
