About the P2 Mini 5.0 Vacuum Tube

The Douk Audio P2 is a versatile mini vacuum tube preamplifier featuring Bluetooth 5.0, USB player support, and multiple audio inputs including RCA and TF card. It uses 6K4 tubes by default, which can be replaced with other compatible tubes like 6J1, 6J4, GE5654, 6AK5, or 6*1n to customize the sound character. The P2 can function as a tube preamp connected between an audio source and amplifier or active speakers, a headphone amplifier with simultaneous RCA and 3.5mm headphone outputs, and a digital player supporting MP3, WMA, APE, FLAC, and WAV formats from USB or TF cards. It features tone control with NE5532 operational amplifier allowing separate adjustment of treble, mid, and bass. The device has a black aluminum body, power and input mode indicators, and comes with a full-function remote control. It requires a DC 12V power supply and is suitable for home and desktop audio use. Note that it cannot drive passive speakers or be used directly with turntables.
