Description / iBasso DC04U Dongle DAC
DC04 Ultra, The Ultra-grade Dongle
The DC04U is not just an upgrade of the DC04PRO, but a complete "Ultra-grade" overhaul.
With a powerful 980mW + 980mW @ 32Ω output, support for 3.5mm microphone calls, and a stainless steel shell, the DC04U delivers a comprehensive upgrade in both functionality and user experience. 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
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? Effortless. No external power is needed, fully unlocking the potential of various IEMs and headphones.
A More Vibrant User Experience
The 0.96 inch multi-color display features dynamic visuals, perfectly blending functionality 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.
The Dual CS43198 Flagship DAC
Dual CS43198 flagship DAC chips create 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 delivers a clear sound, expansive soundstage, and a naturally pleasing listening experience.
FPGA + Femtosecond Oscillator
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.
±0.1V Precise Adjustment
The DC04U is equipped with an independent four-channel balanced headphone amplifier circuit, featuring a refined signal amplification path that is designed to achieve a better channel separation and high driving ability. The headphone amplifier power supply ranges from ±4V to ±6V, with each level adjustable in ±0.1V increments, allowing the user to fine-tune their listening experience.
