- Please note that this product is a preamplifier. It is not an amplifier and needs to be connected with an amplifier or active audio devices. Also, it is not a phono preamp and can't work with a turntable. For noise issue:
- There is a large probability that the low-quality audio cable causes the static noise.
- Please make sure the sound source is fine since tube amplifiers will amplify all sound including the noise.
- Please check whether the tubes are plugged well on the tube sockets or not.
- Devices like routers, mobile phones will also interfere in the audio signal and may cause static noise.
- If your problem can't be solved, please feel free to contact us. We will be very glad to help you and try our best to make you satisfied.
