Why is the volume so low when I connect my turntable to my Fosi Audio TB10A amplifier?

  Jeremy RoseJul 27, 2025
  If the volume is extremely low when connecting a turntable to your Fosi Audio TB10A amplifier, it may be because turntables often lack a built-in preamp. If your turntable doesn't have a built-in preamp, you'll need to add an external phono preamp before connecting it to the TB10A. If your turntable has a built-in preamp, make sure to switch the preamp on before connecting to the TB10A.

  If there is no sound from your Fosi Audio Amplifier TB10A, first check that the power supply cable is connected and the power indicator is on. Ensure the indicator light is on when powered. Then, verify that both the TB10A and your audio source are turned on and not set to minimum volume; if possible, test with a different source. Also, check the speaker wire connections and ensure they are correctly connected. Finally, inspect the cables for looseness or damage, as incomplete connections are a common cause of no sound.

  If the power indicator on your Fosi Audio Amplifier TB10A doesn't light up, ensure the AC power cord is securely connected to both the power supply and the AC outlet. Verify that the AC outlet is supplying power and that the power LED on the power supply stays on. If the issue persists, try replacing the power supply with another one that is 12-24V DC. If you are sure that the power supply is defective, please contact support.
