• Multiple audio inputs: with Bluetooth/RCA/U-disk/TF card inputs, can be perfectly compatible with iPod, Phone, MP3, TV, CD players, laptop, desktop computer or other streaming media players etc., satisfy most requirements of common home audio system use.

• Multiple functions:

P2 can be used as a tube preamp, connected between audio source and amplifier or active speaker to greatly improve the sound quality. Default 6K4 tubes, and can be directly replaced by 6J1/6J4/GE5654/6AK5/6*1n to enjoy HiFi sound of different styles.   P2 can be used as a headphone amplifier, convenient to listen to lossless music alone or at night. The RCA and 3.5mm headphone jack can output at the same time to meet more needs.   P2 can be used as a digital player with U-disk and TF card inputs, supporting MP3 and other lossless format such as APE, FLAC, WAV, WMA. No need for any driver, plug and play, convenient to enjoy fun even on the road or outdoors.

• HiFi clear sound with tone control and reasonable circuit layout:

Adopting vacuum tubes design to filter out the digital sounds of common sound sources, making the sound warm and sweet, full and mellow, much softer and more listenable.   Using NE5532 op amp for tone control, treble/mid/bass can be adjusted separately, easy to adjust more delicate sounds of different styles. Pluggable op amp socket design, easy to change other op amps to enjoy different sounds.

• Mini size and exquisite appearance, black aluminum case make it more fashionable and powerful. With power/input mode indicators to clearly show the working status in real time, and full-function remote control makes the operation much easier, very suitable for home and desktop audio system use.

Warm tips: 1. From 29/05/2024, the 6K4 tubes will be upgraded to American 6186 or 6AG5 (will be shipped at random) but the price remains the same.  2. P2 is a tube preamp which needs to work with amplifiers or active speakers, cannot drive passive speakers or used with turntables directly. In RCA input mode, the previous / next song function is invalid. 3. The USB interface only supports U-disk and USB 2.0 thumbdrive, not support PC-USB. And the RCA and 3.5mm headphone jack can output at the same time. 4. Want upgraded GE5654 vacuum tube please click: LINK. And for safer delivery, the remote control may not include battery(CR2025), please prepare it by yourself. Parameters
