Product Information

Recently we have tried most of middle-class digital media players as the audio source with line level output. we have found that the most origin of the analog audio signal is DAC that can significantly affect the sound signature of the entire portable audio system. In view of this, we have started to develop a middle-class USB DAC with an ultimate-graded DAC chip – Cirrus Logic (Wolfson Microelectronics) WM8741. The centralized warm vocal with large soundstage and high analytics is the main characteristic of the analog signal output from WM8741. The TCXO 0.1 ppm/°C 12.0000 MHz active oscillator is introduced in D1 to minimize jitter for accurate PCM signal reproduction. With our own-design low-pass filter (LPF), the power consumption can be reduced for the same performance to remove ultra-high frequency noise to prevent any resonance from the amplifier of the next stage.

This USB DAC can be applicable to both personal computers (PCs) and Android devices via OTG connection. With the official ASIO driver, the music can be reproduced flawlessly in PCs.
