2. If the indicator light is on, check whether the VOL knob is in the minimum position. If so,
turn clockwise to normal Volume
3. If both of the above are normal, check the input device if it is paused, mute, or the volume
is minimized.
Q: Why does the sound break?
A: when the output power exceeds the normal power of amplifier, there will be a large distortion.
you can turn down the front volume or the power amplifier volume, then it is ok.
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 connect signal line, not play music have interferential sound
A: If you use unshielded signal lines, there will be interference signals entering the power
amplifier. If you hate the sound, you are advised to use the shielded signal lines or unplug the
signal lines.
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 overheat protected, and the output power may have
exceeded the designed power, so you can lower the volume a little and 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: The output range of different types of audio source devices is different, the mobile phone
is usually 0.35mV, and the CD is 1V.The signal output amplitude of the sound source will directly
influence 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: Speaker and amplifier is a very sensitive equipment, also need to know each other, and the
matching process, usually the sound will be good after the new power amplifier and the speaker
work more than ten hours
