    High-Performance DAC Chip: AKM4493SEQ

    The KP1 utilizes the AKM4493SEQ DAC chip, renowned for its superior audio decoding capabilities. This chip ensures high-fidelity sound reproduction, delivering clear and detailed audio output. The AKM4493SEQ's advanced features allow the KP1 to support high-resolution audio formats, making it an excellent choice for audiophiles seeking top-tier sound quality in a portable device.

    60-Level Analog Volume Control

    The KP1 offers a pair of volume buttons for precise volume control, with each short press increasing or decreasing the volume by one level. Holding the buttons allows continuous adjustment, providing up to 60 levels of fine-tuned volume control, you never have to worry about the volume being too loud or too soft again. The 60-level volume control provides precise and smooth adjustments for optimal listening.

    Independent Operational Amplifier Chips

    Equipped with dual RT6863D operational amplifier chips, the left and right channels are independently amplified. These chips feature low noise, low distortion, high open-loop gain, and high power supply rejection ratio. Utilizing BJT technology, they provide a linear output current of over 100mA.

    High Gain and Low Gain Mode

    The KP1 includes high and low gain settings, enabling users to tailor the output to their specific headphones' sensitivity. This feature ensures that even high-sensitivity headphones can be driven effectively without distortion. 

    Press and hold both volume buttons for less than one second to switch between Standard Mode and High-Gain Mode (default at startup).

    • Standard Mode: Balanced, very friendly to low-impedance and high-sensitivity in-ear monitors, with good control and clean, transparent sound.
    • High-Gain Mode: Enhances intensity and energy for an overwhelming listening experience.

    Exquisite Circuit Design for Pure Sound

    It features multiple voltage regulations and precise power supply: up to six regulated power outputs for the ICs and separate power supplies for digital and analog circuits, adopting ultra-low noise LDO for critical analog circuits, creating high fidelity audio and wide sound stage. 

    The USB hot-plug Click/POP noise suppression circuit protects your headphones from noise impact. It also includes common-mode filter elements for the USB interface to effectively suppress high-frequency interference that can be introduced when using longer USB data cables, ensuring the quality of USB data transmission.

    True Hardware Decoding, True Hi-Fi

    Supports 32bit/768kHz native DSD512 (22.4MHz). The KuangPai KP1 is a new generation flagship product supporting 32bit/768kHz and native hardware decoding of DSD512.

    Nintendo Switch Compatibility

    Hold the volume up button while inserting into a Nintendo Switch. When the red light flashes slowly, it indicates UAC1.0 mode, functioning as an external DAC amplifier for the Switch, enabling high-end headphones to be used with the gaming console.

    Precision CNC Housing

    Crafted from aerospace aluminum alloy with tight cutting and strict process control, the KP1 features millimeter-level precision, offering a lightweight, aesthetically pleasing, and premium build.
