Notice: As a phono preamp, it is suited for MM turntables only. Do not support MC turntables. As an AUX preamp, it is suited for devices like CD, DAC, PC, cellphone. Please note as a phono preamp, it can only work with MM turntables. Please note your turntable should have no built-in phono preamp. If it has, please make sure there is a PHONO OUT/LINE OUT switch and you should put it on PHONO OUT position. We do not recommend using it with class D amplifiers since most class D amplifiers have much noise. Parameters: 1. RIAA phono part: RIAA freq response 20hz-20kHz +/- 0.5dB, S / N ratio>...

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]
