Feature:1. MU-604 is a high-end digital audio decoding preamp. It integrates USB, Optical and Coaxial audio input, decodes and outputs one balanced and one AUX OUT, providing high-quality analog signal to your amplifier or active speakers.2. The USB adopts the XU208 chip of XMOS, adopts asynchronous transmission and playback processing, and supports the maximum sampling rate of 32bit/384kHz, DSD256. Support USB 1.0 and 2.0 switching, adapt to more types of USB audio Device.3. The SPDIF chip adopts CS8422, which supports coaxial and optical input, and the maximum sampling rate supports PCM 24bit/192kHz.4. The DAC uses 2 ES9018K2M chip, which has a higher parameter and sound quality in the balanced output.5. This machine is suitable for matching with some mid-to-high-end amplifiers or active speakers, bringing you a new listening experience.Specification:Features:MU-604 is a high-end digital audio decoding preamp.
