Professionally Designed Audio Circuitry

HiBy has got years of experience in designing premium and high-end audio gears. Previously, they have designed many HiFi audio gears including portable DACs and Digital Audio Players. Using that experience, Professional acoustic engineers at HiBy have designed the FC4 with a professional audio circuitry.  They have equipped the device with a premium Dual DAC chipset along with a specially designed FPGA architecture consisting of dual independent crystal oscillators.

 

High-Quality Sabre DACs

ESS DAC chips are widely used in HiFi audio gears across different price segments. They have a huge catalog of products designed to suit the needs of audiophiles on every budget. HiBy FC4 adopts two ES9218PC DAC chips that support high-resolution 32-Bit audio signals. It achieves a lower distortion rating of 0.0006% and a high SNR value of 123dB promising high-quality performance for the users.

Independent FPGA-Based Dual Crystal Oscillators

The FPGA section consists of two 45.158MHz and 49.152MHz independently used crystal oscillators. They effectively protect the output signal from jitters and provides a smooth and clear audio experience.

 

Exquisite and Compact Build

HiBy FC4 has an all-metal construction. It has a rich, smooth textured finish with physical hardware volume keys available to easily adjust the volume on the go. The device looks exquisitely finished just like all the other products from HiBy.

Dual Headphone Outputs With Powerful Amplification Section

HiBy FC4 features dual headphone output ports. The device houses a single-ended 3.5mm and a balanced 4.4mm output port. HiBy has designed the FC4 with a powerful amplification section. The device gets a powerful output rating of up to 340mW @ 32Ω of load. This is a best-in-class output rating making the FC4 suitable for almost all the IEMs and some headphones too.

 

8X MQA Support

HiBy FC4 supports 8x MQA unfolding. It provides high-resolution master-recording level sound quality performance by fully unwrapping the recording to its true form.

Multi-Color RGB Light Indicator

HiBy FC4 houses a multi-color RGB indicator light that glows into different colors depending on the bitrate of the active file. It glows into Green, Blue Magenta for MQA signals, Yellow, Aqua, and Orange for PCM signals(different bitrates), White for DSD signals, and Red when the music is paused.

 

Price & Availability

HiBy FC4 is launched officially for 89$. It comes right between the FC3 at 69$ and the flagship FC5 at 159$. Check out more details here!!
