Flagship-Grade Dual DAC Chipset

The iBasso DC04 Pro features a premium Dual DAC Chipset housing two CS43131 high-performance 32-Bit DAC chips from Cirrus Logic. They offer best-in-class performance with ultra-low distortion and high signal-to-noise ratio performance, producing a clean output with high dynamic range.

High-Resolution Audio Signal Decoding

The iBasso DC04 Pro decodes high-resolution audio signals with support for all leading high-resolution PCM and DSD audio signals, supporting up to 32-Bit/384kHz PCM signals and up to DSD256 signals natively.

Dual Headphone Output Ports (3.5mm + 4.4mm)

The device provides a single-ended 3.5mm output and a 4.4mm balanced headphone output option, making it compatible with most IEMs and headphones straight out of the box.

Powerful Amplification Circuit

The DC04 Pro utilizes dual RT6863 amp chips that produce powerful signal amplification while maintaining low THD+N distortion and high SNR performance.

Exclusively Premium Finish With All-Aluminum Build

The device has an exclusive unibody build with an all-aluminum chassis and tempered glass panel for a solid structure, offering an elegant finish that looks exquisite.

Clean Performance With Ultra-Low-Noise LDO

The ultra-low noise LDO supply circuit ensures clean power is delivered to different components on the audio circuitry, enhancing overall performance.

FPGA + KDS Crystal Oscillator

The in-house developed FPGA algorithm supported by a KDS crystal oscillator helps in delivering clear and accurate high-resolution audio signal decoding performance.
