Features: Bridging Chip CB5100 DAC Decoding Dual chip CS43131 Supports Recording 8-Band EQ Flexible Adjustment PCM 384kHz/32bit, DSD256 Advanced DAC Decoding The Black Pearl has a built-in USB audio bridge chip (CB5100) and dual DAC chips (CS43131) that provide low-power, high-performance decoding. Together, these three components rapidly enhance data processing and digital signal transmission, support high-resolution audio, and deliver richer, more detailed sound. Exceptional Resolution Capable of decoding PCM 384kHz/32bit and DSD64/DSD128/DSD256 formats, The Black Pearl captures every nuance with remarkable precision. It renders even the faintest background details and ensures smooth transitions between frequencies, maintaining a wide dynamic range and effective noise suppression for a truly pure listening experience. Versatile Connectivity Designed for broad compatibility, the device offers both a 4.4mm fully balanced differential output and a 3.5mm stereo headphone output. This dual-interface approach allows users to easily connect to a variety of devices, delivering the flexibility needed for any audio setup. Intuitive Status Indicators An integrated three-color status light simplifies operation: blue indicates standby, green shows PCM mode, and red signifies exclusive DSD mode. This clear, visual feedback streamlines user interaction without the need for complex digital displays. Integrated Recording and Calling Beyond high-fidelity playback, The Black Pearl supports built-in recording and calling functions following Android’s standard line control. This feature not only captures rich sound details during calls but also ensures natural voice reproduction, allowing you to enjoy seamless communication alongside your music.
