Please make sure your turntable is equipped with a PHONO signal output instead of a LINE output. GND switch on its back panel is set to connect with the ground by default. However, there may get some loud background noise with a few digital amplifiers. Please try setting it to disconnect with the ground then. With a 3-meter black cable in the package, which can be wired between T11 with huge metal items such as doors or windows if your wall outlet has no ground connection.

It won’t be loud, while a little loud is just normal. Turntable is a kind of analog players and cannot be compared with digital players in this respect. Besides, there are many factors which may lead to bad noise. To find the right reason, you need to do some tests and here are some instructions.Reason A: T11 isn’t connected to ground well.This is the most common and unnoticed reason. Please test it following the steps as below.While the device is playing music, picking up the GND copper part of T11 with your fingers. If the background noise is much lower, then T11 isn’t connected to the ground. For this issue, we prepared a 3m wire in the package for you to solve it by yourself. Just use it to connect the GND with any large mental item in your home like windows or mental tables.Reason B: T11 doesn’t match with your amplifier well.There is a possibility that T11 may not match with some digital amplifiers well, which may lead to very loud noise. This is because digital amplifiers cannot be connected to the ground directly. For this issue, you can just set the T11 GND switch (on the back of it) to OFF.However, this will lead to bad noise from T11 itself as it is not connected to the ground. You can only choose the bearable way. That’s why we recommend using professional pure HiFi amplifiers like AV amplifier or vacuum tube amplifiers (it will be better if the amplifier isn’t equipped with Bluetooth).Reason C: The RCA wire has a poor quality.A good RCA wire will be equipped with an anti-jamming magnetic ring, which can effectively reduce various interference.Q: T11’s power light is on while one or several tubes is not. A: Please check whether the tube is plugged into the tube seat completely. Otherwise please check the tube whether it seems like a thin mist is inside. If so, then the tube is defective and you need to replace it. Payment Fast Shipping Return Policy About us Contact us Payment Safe and secure payment by PayPal.
