Introducing the DC04U: An Ultra-Grade Portable DAC/AMP
The DC04U is engineered to provide a professional-grade music experience in a compact form factor. Despite its size, it delivers a maximum output of 980mW+980mW at 32Ω. Key features include a three-stage gain function, a 3.5mm 4-pole inline microphone input, and a durable stainless steel chassis. The device operates efficiently solely on bus power, achieving stable high-performance drive. Its design integrates low distortion, high dynamic range, and high output, enabling the DC04U to achieve exceptional parameters that align with its “Ultra” designation. This device is positioned to lead the movement towards high-output portable DAC/AMPs.
Advanced Audio Technology
Dual CS43198 DACs
The DC04U incorporates two CS43198 DAC chips, enabling a 4-channel full-balanced circuit. It supports high-resolution audio up to PCM768 and native DSD512. Dynamic Range Enhance (DRE) technology is included to ensure ample headroom. Through refined tuning techniques, the full potential of the CS43198 chips is realized, delivering transparent sound, a spacious soundstage, and natural audio reproduction.
FPGA + Femto Clock Crystal Oscillator
Leveraging iBasso’s accumulated FPGA algorithm expertise, the DC04U utilizes dual femto clock crystal oscillators. Hardware and software calibration of the clock source significantly reduces jitter in digital signal transmission. This ensures a clean transmission path for audio signals, resulting in accurate and pure digital signals for faithful sound reproduction.
Independent 4-Channel Full-Balanced Amplifier Circuit
The device features an independent 4-channel full-balanced amplifier circuit with an updated design, achieving enhanced channel separation and amplifier drive control. Beyond its impressive output performance of 980mW+980mW at 32Ω, the amplifier’s power supply can be adjusted from ±4V to ±6V in 0.1V increments, offering a more versatile listening experience.
Full-Color Screen & Side Buttons for Enhanced User Experience
The 0.96-inch full-color screen blends dynamic visuals with practicality and convenience. Users can select their preferred color scheme and switch between a static UI for clear status indication and a dynamic UI that displays a level meter. The device’s side features three physical buttons, offering a minimalist and smooth feel for adjusting volume and accessing various settings directly without needing an application.
