FOSI AUDIO P3 TUBE PREAMPLIFIER
The Fosi Audio P3 is a compact tube preamplifier and headphone amplifier designed for desktop and small Hi-Fi systems. It combines a stereo RCA input with Bluetooth reception, variable analogue outputs and a front headphone connection, making it suitable for use ahead of a power amplifier, active speakers or headphones.
GENUINE 5654W TUBE STAGE
The P3 uses two replaceable 5654W vacuum tubes in its preamplifier circuit. Fosi Audio specifies an internal tube operating voltage of up to 54V, allowing the valves to operate as an active part of the amplification stage rather than serving only a decorative function. The tubes can also be replaced with compatible alternatives for users interested in tube rolling.
BLUETOOTH 5.1 WITH APTX HD
Wireless audio is handled by a Qualcomm QCC3031 Bluetooth 5.1 receiver. Supported codecs include SBC, AAC, aptX, aptX HD and aptX Low Latency, providing convenient playback from compatible phones, tablets and computers without requiring a separate Bluetooth receiver.
HEADPHONE AMPLIFIER FOR 16–300Ω LOADS
A 3.5mm headphone output is located on the front panel and supports headphones from 16Ω to 300Ω. Output power reaches 250mW at 16Ω and 150mW at 32Ω, with lower output available for higher-impedance headphones.
BASS & TREBLE CONTROL
Dedicated bass and treble controls provide direct analogue adjustment, with up to ±12dB bass and ±6dB treble range. Central detents make it easy to return the controls to their neutral positions, while the main volume control governs the connected headphone or downstream system level.
COMPACT PREAMP SYSTEM HUB
The rear panel provides stereo RCA input, stereo RCA output and a 3.5mm AUX output. This allows the P3 to feed a stereo power amplifier, active speakers or another compatible line-level component while also providing Bluetooth input and headphone listening from the same compact unit.
