All analog IO are input and output capable, and headphone amplifiers are also integrated at each analog output. All analog IOs can be re-tasked according to user’s definitions, or automatically switched depending on the connected device type.


Support for 16/20/24-bit S/PDIF input and output offers easy connection of PCs to high-quality consumer electronic products such as digital decoders and speakers. The series incorporates Realtek proprietary converter technology to achieve 106dB Signal-to-Noise ratio (SNR) playback quality and 101dB SNR recording quality, and is designed for Windows Vista premium desktop and laptop systems.

谢谢楼上的兄弟，其实我就是想知道这个889到底是885的改进呢还是简化版，呵呵。
