Premium Dual DAC Arrangement:

xDuoo has equipped the latest MU-604 with a premium Dual DAC Chipset from ESS Sabre Technologies. The device houses two ES9018K2M high-performance DAC chips. They are 32-Bit DACs that allow the MU-604 to decode high-resolution PCM and DSD signals with great precision and clarity.


Dual High-End Crystal Oscillators:

In order to get the best out of the MU-604, xDuoo has designed the device with two high-quality active crystal oscillators as the clock sources. They work at 44.1K and 48K and their different sampling rates respectively. They enable jitter-free high-resolution performance with the MU-604.


8-Core XMOS USB Receiver:

xDuoo MU-604 comes with an XMOS XU208 USB receiver chip. It works in asynchronous transmission mode and supports WASAPI, ASIO, and KS core stream modes. XMOS XU208 supports high-resolution PCM(32-Bit/384kHz) and native DSD256 signals.


Dual USB Modes:

xDuoo MU-604 supports dual USB modes, USB 1.0 and USB2.0. The USB 1.0 mode is compatible with older-gen PC and game consoles like Nintendo Switch and PlayStation. The USB 2.0 mode is made for the latest-generation PC. It also benefits with xDuoo USB driver enabling accurate high-res decoding on the system.


Supports Multiple Input/Outputs:

xDuoo MU-604 supports different inputs and outputs. It takes digital input via USB, Coaxial, and Optical input ports. For analog output, the MU-604 features single-ended RCA and balanced XLR output ports.
