7: Why does the amplifier stop working after a period?
And after a while it work again?
• The amplifier is in this case normally overheat protected, and the
output power may have exceeded the designed range, so you can
lower the volume a little and try again.
8: How much power does this product use in standby
mode? Can this amplifier be left on all the time?
• Power stable rated output of about 180watt. This is a Class D
amplifier, which consumes some power in standby mode and has
a stable rated output of about 150watt.
9: When the volume adjustment on the amplifier stays the
same, why is the speaker's output volume different while
different devices are used ( such as CDS and mobile
phones ) ?
• The output voltage of different types of audio sources is different.
For the mobile phone, it is 0.35mV, but the CD 1V. The signal
output amplitude of the devices will directly influence the volume.
10: Why the sound of the power amplifier is not so good at
the beginning and for the high frequency it is also not
clear, but after working for 10 hours the sound is normal
again?
• Speakers and amplifiers are very sensitive equipments. They
need also to match themselves with each other. So usually the
sound will be good again after the new power amplifier and the
speaker work more than 10 hours.
11: Why the sound quality is not so good?
• Turn down the volume of the input device and turn up the volume
of the amplifier.
