How to fix Fosi Audio Amplifier if Bluetooth is intermittent?
If the Bluetooth connection on your Fosi Audio Amplifier is intermittent, try using another Bluetooth device to test the connection. Make sure there is no interference from other electronic equipment between the BT20A and the audio source. Position your device closer to the BT20A. Also, try replugging the power adapter.
Why is there no sound from my Fosi Audio BT20A Amplifier?
If there is no sound from your Fosi Audio Amplifier, first check if the power supply cable is connected to the BT20A and if the power indicator is on. Ensure the BT20A's indicator light is on when powered. Verify that the BT20A and your audio source are turned on and not set to minimum volume; if possible, test with another source. Check the speaker wire connections from the audio source to the amplifier for correct connection. Also, ensure the cable isn't loose or damaged, as incomplete connections can cause this. Finally, if using Bluetooth, ensure it is paired, as Bluetooth playback interrupts RCA input; disconnect Bluetooth to use RCA input.
