PORTABLE USB R2R DAC & AMP

REVOLUTIONARY USB DAC/AMP WITH DARWIN ARCHITECTURE TECHNOLOGY

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.

R-2R DAC DARWIN ARCHITECTURE

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.

CONVENIENT OS/NOS SWITCH FOR ON-THE-GO USAGE

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.

DARWIN FIR FILTERS

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.

ENHANCED HEADPHONE AMPLIFICATION

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.

DECODING HI-RES AUDIO SIGNALS WITH HIBY FC6

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.

SEAMLESS INTEGRATION WITH HIBYMUSIC APPLICATION

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.
