What caused the noise or AC noise for the amplifier?
Summary：Noise from audio source,such as CD player,Automatic player,tuner,USB ect.
◪1. Noise from audio source,such as CD player,Automatic player,tuner,USB ect.
◪2. Bad quality signal line or the line is too long .
◪3. Volume potentiometer problems, there is sound when increase the volume, there is dust if it use for a long time,we suggest to change the potentiometer or wash it with alcohol
◪4. The working voltage is too low, it is recommended to match the voltage regulator and our power sequence with display of the voltage
◪5. Power line and audio line cloth together, the strong and weak electricity should be separated wiring.
◪6. Amplifier power is too small, the load power is too large,amplifier output distortion
◪7. The signal line is bad, the main audio signal line with the power input socket lotus is in bad connection or bad connection or the bad connection of ground line.
◪8. Pre-amplifier volume or signal is too large, we suggest increase the volume of the amplifier and decrease the volume of the pre-amplifier
◪9. Amplifier's internal components were damaged
