Please note that noise will happen in these situation:
(1)Hardware problem:
-Power supply is not sufficient or not stable;
-Using switch power supply
-Using transformer as power supply and without shield & isolation; wdo not avoid interference
-Local at the environment with electromagnetic interference
-Audio input has its own problem
(2)Software problem:
-Audio driver setting
-Music Player effects setting
Solution:
(1)Hardware problem-> The power supply should not be placed too close to the amplifier board in order to avoid electromagnetic interference. It is better to use high quality power supply which offers stable power. If you use power transformer, using an iron sheet to cover the transformer is highly recommended.
(2)Software problem-> When you connect the amplifier to telephone or computer, you can turn off the special effects software or sound card driver effects settings. Using the software after making sure they will not take effect on the sound effect.
