The HiBy FC6 is the first USB DAC/AMP on the market with their in-house developed Darwin Architecture Technology, which was previously utilized in premium digital audio players. This innovative audio architecture combines an R2R DAC with FIR filters and an NOS/OS switch, providing users with a unique combination of traditional R2R characteristics and digital filters within a single unit.

HiBy FC6 features a custom R2R ladder array DAC design that takes advantage of 96 high-precision resistors arranged in an R-2R network. In addition, its undisclosed advanced technology for linearity compensation which delivers the unique audio experience that combines the characteristic warmth and richness of R2R DACs with the precise accuracy typically associated with modern DACs.

The FC6 offers users the flexibility to switch between NOS (Non-Over Sampling) and OS (Over Sampling) modes through a dedicated key. In NOS mode, the audio is presented in its unprocessed, raw form, delivering a distinct analog quality with enhanced clarity and authenticity. On the other hand, OS mode utilizes oversampling and ultrasonic low-pass filters to eliminate aliasing artifacts, resulting in a smoother sound. OS mode unlocks the full range of digital filters available on the FC6.

HiBy has implemented a discrete headphone amplification circuit in the FC6 to match the high standards of top-tier Digital Audio Players. The circuit features dual OPA1622 amp chips and a 4-way independent current-mode amplification design, ensuring exceptional audio quality for headphone users.

The biggest advantage of utilizing the Darwin Architecture lies in the inclusion of digital FIR filters, offering a wide range of options to cater to diverse music styles. These filters facilitate up to 16x oversampling and provide numerous customizable filter choices directly on the FC6 device. This empowers users to personalize their audio experience according to their preferences and requirements.

The HiBy FC6 provides extensive decoding support for all major audio formats. It effortlessly handles high-resolution audio signals, accommodating bitrates up to 32Bit/768kHz for PCM signals and Native DSD512 signals. The FC6 excels in delivering true studio-grade performance by offering 8x unfolding capabilities for MQA audio files.

The FC6 fully leverages the potential of your smartphone as a source by seamlessly integrating with the HiByMusic application. It supports the exclusive USB mode of the HiByMusic app, enabling flawless, bit-perfect decoding of lossless audio directly on the device.

The FC6 is equipped with convenient hardware volume keys, allowing you to effortlessly modify the volume on the move. These physical keys offer up to 32-step volume control, ensuring accurate adjustments specifically tailored for high-sensitivity in-ear monitors (IEMs) and headphones.
