【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. A GREAT BLEND OF RETRO AND MODERN: P1 PLUS boldly reimagines the look of HiFi audio equipment, integrating pluggable VU meters, retro military-grade vacuum tubes, and a clear OLED screen. It not only adds warmth to the sound, but also vividly displays the dynamic changes of the audio signal, allowing you to dive into the HiFi world and immerse yourself in an exciting sound and visual feast at the same time. Premium chipset unleashes the limits of performance: QCC5125 Bluetooth chip supports APTX-HD and LDAC, achieving MAX 24bit/96Khz transmission. SA9137L USB chip and ESS9018K2M DAC chip process PCM data up to MAX 384KHz/32bit and DSD256. TPA6120 amplifier chip easily drives headphones from 16Ω to 600Ω with MAX 750mW output power. Moreover, by replacing the two pluggable NE5532 op amps, you can replace them with various dual op amps to tune your sound. Authentic Tube Amplifier and Sound: The P1 PLUS preamp circuit boosts the voltage to 100V, allowing the tubes to perform at their best to provide a warm and rich audio experience. Our unique technology faithfully reproduces sharp high tones, rich midrange richness, and deep rhythmic bass. The pluggable socket design allows you to customize your own sound through tube rolling and sound shaping. Versatile Audio Inputs and Outputs: P1 PLUS offers Bluetooth, USB, coaxial, optical, stereo RCA, and 3.5mm AUX inputs, and also has optical, stereo RCA, 3.5mm AUX, and 3.5mm headphone jack outputs. It perfectly meets all your home audio needs and allows you to use headphone, RCA and AUX outputs simultaneously, making it easy to create multi-channel systems and minimizing the hassle of cable plugging. Enhanced details elevate the P1 PLUS to perfection: it features a tone knob for precision adjustment of bass and treble, a remote control that puts all settings at your fingertips, and a VU with variable color to match different listening spaces. It features a smart metal body that seamlessly blends retro charm with modern design.
