Experience your headphones as they were meant to be heard, even high-impedance studio models. Versatile Tube Preamp – Doubles as a stereo preamp to add warm tube character to your powered speakers or home amplifier. Simply connect the P32 to your speaker system’s AUX/RCA input for a significant audio upgrade across your entire setup. Warm & Rich Tube Sound – Instantly improves your audio with the smooth, mellow tone of vacuum tubes. Music becomes more enjoyable with richer detail and clearer vocals – all without any background hiss, so quiet passages stay truly quiet. Plug-and-Play Compatibility – Ready to use with all your devices via RCA or 3.5mm AUX input (connect your PC, phone, TV, etc.). Both 3.5mm and 6.35mm headphone outputs are built-in, so you’ll never have to hunt for a adapter to fit your headphones. Future-Proof Customization – The P32 can grow with your evolving taste. Both the vacuum tubes and dual op-amp chips are swappable, allowing you to easily fine-tune the sound or upgrade components without buying a whole new amplifier each time. Warm tips
1. Please use the supplied DC 5V/2A power adapter to ensure optimal performance of the P32. If using other power supply, make sure it provides at least 2A current. Otherwise, the P32 may not function properly.
2. The RCA and AUX inputs, as well as the 3.5mm and 6.35mm outputs, work at the same time. Please don’t connect the two inputs at the same time, or else audio signals will be mixed.
3. P32 adopts 2PCS pluggable NE5532 op-amps, which can be upgraded by LME49720NA-DIP-8 or any other dual op-amp in an 8-pin package with an output current exceeding 50mA.
4. P32 adopts pluggable tube socket, default 6J5 vacuum tubes, can be replaced by 6J1, 5654, 6AK5, EF95 etc. For a full list of compatible tube models, please refer to the user manual.
5. P32 can easily drive all headphones even with high-impedance such as HD580/HD600/HD650/K701/K702/Q701/DT880/T70/T90/SR225/SR325/RS1e etc.
