Product Details
- True Tube Amplification: The preamp circuit elevates the voltage to 54V, ensuring the tubes work to their full potential, delivering a warm and rich experience. The unique preamplification technology delivers pure audio signals, faithfully reproducing crisp high tones, full midrange richness, and deep, rhythmic bass. Important Tips: Remove the copper rings for effortless installation of the tubes on the P3
- Bluetooth 5.1: Equipped with the Qualcomm QCC3031 chip, the P3 preamp guarantees impressive wireless sound quality and low latency, with compatibility for aptX HD and aptX LL codecs formats. Furthermore, the inclusion of a manual reset button prevents accidental connections by others, enhancing connection reliability
- Versatile Connectivities: The P3 provides Bluetooth/RCA inputs and RCA/AUX OUT/3.5mm headphone outputs. It can help create a 2.1-channel audio system by connecting active speakers/an amplifier and a subwoofer. As a headphone amplifier, it supports headphones with impedance ranging from 16Ω to 300Ω
- Durability: Dual RCA to 3.5mm audio cable is made of rugged black PVC jacket wrapped in 48-strand nylon braid resists tangles, kinks and daily wear, flexible yet tough enough for studio, stage or tight home-theater setups
- Stable Connection: Gold-plated RCA/3.5mm connectors resist oxidation/corrosion, boost conductivity, cut signal loss, and ensure smooth audio transmission
