Precautions
1. As a genuine tube preamplifier, please allow me 15 seconds to preheat
the tubes after powering on, and then the sound can be output normally.
2. Avoid plugging and unplugging cables while the device is powered on to
prevent abnormal noises. This can also easily damage the product.
3. If you need to replace the tubes, please do so when the tubes have
cooled down to avoid burns or damage to the product.
Frequently Asked Questions
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.
