1. After connecting the product and turning it on, there's no sound during playback?
Since the P3 is a tube preamp, the tubes require about 15 seconds to preheat before they can operate properly. If there is still no sound after 15 seconds, please check if the cables are connected correctly, if the tubes are properly plugged, and if the correct input mode is selected.
2. Why is the power indicator light very dim or constantly flashing after powering on?
A blinking blue light in Bluetooth mode indicates it's awaiting a connection, and the light will remain steady blue once connected. A flashing power indicator light in RCA mode might suggest insufficient power supply. Please ensure you're using a power supply between 12V/1.5A and 12V/3A.
3. How are the headphone output, RCA output, and AUX output on the Fosi Audio P3 controlled? By default, Fosi Audio P3 prioritizes headphone output, with RCA and AUX outputting simultaneously. This means both RCA and AUX will output signals at the same time; however, when a headphone is plugged in, the signal will switch to the headphone output, and there will be no signal on RCA and AUX outputs.
4. How do I clear the Bluetooth pairing record?
On the rear panel of the Fosi Audio P3, there's an RST button. Press and hold for 3 seconds to clear Bluetooth pairing. If you're in Bluetooth mode at this time, the indicator light will flash blue.
