1. No shortcomings, all pull full
Create a true hexagonal warrior
The DC04PRO is a combination of many specialties - dual CS43131 flagship DAC, synchronous rectification + ultra-low noise LDO power supply, four independent balanced earphones, self-researched FPGA technology, KDS femtosecond crystal, multi-function APK, CNC one-piece casing, double-sided glass. The DC04PRO is a full-fledged small tail with outstanding sound quality, high thrust, high current output, dual interface, interchangeable cables, excellent power control, and outstanding indicators.
2. Dual CS43131 flagship DAC
Ultra-low noise LDO to ensure pure power supply
The DC04PRO uses Cirrus Logic's flagship DAC with Master HiFi™ technology, the CS43131, for superior performance and listening. The DC04PRO uses a low noise LDO for RF and analog circuits.
The DC04 PRO has a low noise floor of nanovolts!
Synchronous rectification + ultra-low noise LDO
Small tail power supply technology top work
The DC04PRO uses an independent power supply structure to ensure adequate power supply to the small tail through synchronous rectification, low-noise high-speed LDO, and high-efficiency DC/DC boost technology to bring dynamic, cohesive and powerful sound like a player.
4. Independent 4-way fully balanced earphone circuitry
10V high voltage power supply
The DC04PRO uses a dual RT6863 to build a 4-way fully balanced amplifier with ultra-low distortion, a linear output current of up to 100mA, and a thrust of 280mW@32Ω at 10V. With a well-designed analog circuit, the DC04PRO sounds full, warm, transparent, and delicate, saying goodbye to the thin, cold, and harsh digital sound of cell phones.
5. FPGA technology + KDS femtosecond crystal
Effective jitter reduction and distortion reduction
We use the self-researched FPGA algorithm accumulated on the player, and boldly apply it to DC04PRO. At the same time, the KDS femtosecond crystal is used as the clock source for the FPGA, effectively reducing jitter in the clock and audio data, allowing accurate sound restoration and significantly reducing distortion.
6. Breakthrough in core indicators
Pioneer a new level of small tail
The index is not the only standard to verify the sound quality, but it is enough to illustrate the good or bad materials and design ability of the product. In the DC04PRO, the AP measurement index has been raised to a new level.
Signal-to-noise ratio 131dB
Bottom noise Less than 0.9μV
Balanced thrust 280mW@32Ω
Low to nanovoltage, truly "almost 0 noise"!
7. Better power control
Free adjustment, easy to hold
DC04PRO lower power consumption, and fully meet the needs of free adjustment. Compared to similar small tail up to 700, 800mW power consumption, the DC04PRO power consumption and heat is lower, giving you excellent The DC04PRO's power consumption and heat generation is lower than similar small tail up to 700, 800mW, giving you excellent sound quality and long-lasting listening.
8. with Android APK

The Type-C to Lightning cable can be replaced to experience HiFi sound on iOS devices. Through the free C to A adapter, connect PC and MAC, transform into a USB DAC, a multi-purpose more valuable.
11. 4.4mm + 3.5mm Dual Interface
Balance and single-ended at the same time to get
12. Multi-color indicator
All status at a glance
13. operation introduction
DC04PRO is plug-and-play on Android devices with Android 5.1 or above (depending on the system or hardware of the device, there may be compatibility differences on very few Android devices). To experience the full functionality of the DC04PRO, it is recommended that you install the iBasso UAC, the exclusive Android APK for the ibasso decoding earphone cable, which allows for fine volume adjustment as well as the ability to change filter and channel balance settings. Some models of Android devices may require the OTG function to be turned on manually in the system settings. When used with a cell phone, it supports PCM 32bit/384kHz and Native DSD256 output.
