Fosi Audio expands its lineup with the introduction of the P4 Mini Preamp, a compact yet powerful addition designed to meet the high standards of audiophiles. Crafted from all-aluminum alloy CNC construction, the P4 not only boasts a sleek and minimalist design but also provides enhanced resistance to electromagnetic interference, ensuring pristine audio quality.

Equipped with three RCA inputs, the P4 seamlessly integrates multiple audio sources, including CD players, streamers, DACs, cassette decks, and turntables with built-in phono preamps. The high-precision motorized analog potentiometer delivers smooth volume adjustments while maintaining a signal-to-noise ratio exceeding 110 dB and keeping total harmonic distortion below 0.003%. This ensures that every detail of the audio signal is preserved with exceptional clarity.

Users can customize their listening experience with the P4’s treble and bass tone controls, adjustable within a range of ±12 dB. Additionally, the three-level gain adjustment feature allows for optimal sound quality by matching different output levels from various audio sources. The preamp also offers both RCA and 3.5 mm outputs, providing versatile connectivity options for a wide range of audio setups.

Designed to perfectly complement the Fosi Audio V3 Amplifier, the P4 enhances both the visual and auditory aspects of any home audio system. Its compact size makes it an ideal control hub, allowing effortless switching between sources with a single click. The P4 operates within a frequency response of 20 Hz to 20 kHz (±0.1 dB), delivering accurate sound reproduction across the entire audible spectrum.

Overall, the Fosi Audio P4 Mini Preamp stands out as a highly reliable and technically impressive component, offering audiophiles a customizable and high-fidelity audio solution. With its robust construction, advanced features, and exceptional performance metrics, the P4 is poised to become a staple in discerning audio setups.
