An Ultra-grade Dongle
DC04U is not just an evolution of the DC04PRO, but a complete "Ultra-grade" overhaul. With a powerful output of 980mW + 980mW @ 32Ω, support for 3.5mm microphone calls, and a stainless steel shell, it delivers a comprehensive upgrade in both functionality and user experience. The DC04U is a dongle with exceptional driving power and outstanding usability. Compared to the DC04PRO, its power consumption is slightly higher by 3.6%, but its effective drive power is increased by 2.5 times, demonstrating excellent power efficiency.
Peak Driving Ability
Always "Desktop Mode"
The DC04U requires no external power supply while continuously delivering a stable output of up to 980mW + 980mW @ 32Ω. Driving in-ear monitors? A piece of cake. Powering full size headphones? effortlessly. No external power needed, fully unlocking the potential of various headphones. The dongle is now stepping into the era of watt-level output power!
Multi-color Display
A More Vibrant User Experience
The 0.96 inch multi-color display features dynamic visuals, perfectly blending a sense of technology with practicality. The three physical buttons on the side provide clear tactile feedback for volume adjustment, filter switching, gain switching, and channel balance setting... From basic operations to fine-tuning settings, everything can be done with a single button press directly on the device, without relying on APPs.
Dual CS43198
The Flagship DAC With A New Feature
Featuring dual CS43198 flagship DAC chips which creates a four-channel true balanced circuit. The DC04U supports PCM 768kHz / DSD 512 hardware decoding and uses DRE dynamic enhancement to perfectly eliminate 0dB distortion. Leveraging iBasso's many years of refined tuning experience, the DC04U fully unlocks the potential of this "old friend": delivering clear sound, expansive soundstage, and a naturally pleasing listening experience.
FPGA + Femtosecond Oscillator
Designed for Exceptional Sound Quality
Exceptional sound quality begins with a precise clock and data reproduction. The DC04U utilizes iBasso's accumulated FPGA audio algorithms, paired with dual femtosecond oscillators. This structure significantly reduces jitter during digital signal transmission, ensuring that the entire transmission chain delivers pure audio signals, resulting in a more authentic, clearer, and more natural listening experience.
