Troubleshooting: 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 cau... [Read More]
Notice: Please turn on the amplifier for about 15 seconds before you connect the audio source and put on the headset. We recommend using 24~600Ω headphones, while armature earphones and headphones that have low resistance and high sensitivity are not suitable. As there will be tube Microphone effect, please keep the amplifier steady while using it. For noise issue, please keep it away from devices like routers, mobile phones or something that may interfere in the audio signal. If there are no interference, please remove all input and listen to see if the noise still exists. If so, the device ... [Read More]
