XDUOO MU-604 Decoder 2*ES9018K2M DAC Chip Two USB Audio DAC

XDUOO MU-604 High-Performance DAC

Dual DAC Chip Design for Superior Sound Quality

The XDUOO MU-604 features two high-performance ES9018K2M DAC chips, delivering exceptional sound clarity with extremely high Signal-to-Noise Ratio (SNR) and ultra-low Total Harmonic Distortion plus Noise (THD+N). This ensures a rich and immersive audio experience.

Comprehensive Connectivity Options

Supporting high-standard USB, coaxial, and optical inputs, the MU-604 can be connected to a wide range of devices including desktop CDs, digital turntables, and gaming consoles. With AUX and XLR balanced analog outputs, it can easily integrate with various audio amplifiers, providing high-quality audio output.

Advanced USB Audio Modes

The MU-604 offers two USB audio modes: USB1.0 for compatibility with lower version computer systems and gaming consoles, and USB2.0 high-performance mode for superior audio quality. Simply switch between modes and enjoy optimized sound performance for different devices.

Powerful Decoding Capability

Equipped with the XMOS XU208 USB receiver chip, the MU-604 supports asynchronous transmission mode, drastically reducing jitter and delay. It supports up to PCM384kHz and native DSD256, ensuring top-notch decoding ability that elevates the sound quality of your computer and other digital sources.

High-Quality XLR Balanced Output

Featuring both AUX and XLR balanced outputs, the MU-604 delivers high-quality balanced analog signal output. This enhances SNR, crosstalk, and THD+N, resulting in improved overall sound quality for your audio system.

High-Precision Dual Crystal Oscillators

The MU-604 utilizes two high-quality active crystal oscillators for 44.1kHz and 48kHz sampling rates, automatically switching between them to ensure reliable and independent clock operation without interference. This contributes to the DAC's superior sound accuracy.

Enthusiast-Grade Components

Designed with audiophiles in mind, the MU-604 uses special enthusiast Japanese NICHICON capacitors as the main filter capacitance, offering smooth and warm sound along with splendid high-frequency performance.

Independent Power Supply for Pure Sound

The MU-604 is powered by a separate DC12V power supply, avoiding the noise and interference common with computer USB power supplies. This design ensures a purer sound and prevents the front-end power from being consumed when connected to mobile devices.

OLED Display for Real-Time Monitoring

A high-definition OLED display allows you to monitor the MU-604's decoding status at any time, ensuring that your device is always performing at its best.

Elegant and Durable Design

With a sandblasted textured panel and hard aluminum alloy shell, the MU-604 not only looks sleek and sophisticated but also effectively resists external interference, ensuring durability and consistent performance.
