- [: u, G+ I4 CGeneral Description
The ALC885 is a high-performance 7.1+2 Channel High Definition Audio Codec with advanced lossless content protection technology that protects pre-recorded content while still allowing full-rate audio enjoyment from DVD audio, Blu-ray DVD, or HD DVD discs.
& s/ D( }  {# V% z9 r6 i8 i; l

The ALC885 provides ten DAC channels that simultaneously support 7.1 sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo outputs. Three stereo ADCs are integrated and can support a microphone array with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technologies simultaneously.
$ P4 m) S& v# O; Q; {5 \" A

) }  a7 S$ B' Y- w- M6 |  A- XAll 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.  


The ALC885 supports host/soft audio from the Intel ICH series chipset, and also from any other HDA compatible audio controller. With EAX/Direct Sound 3D/I3DL2/A3D compatibility, and excellent software utilities like Karaoke mode, environment emulation, software equalizer, HRTF 3D positional audio, and optional Dolby® Master Studio™, the ALC885 provides an excellent home entertainment package and game experience for PC users.

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。

现在我板子上的是ALC882, 声音没有旧机上的AD1888大....
