Designed for the following chipset:
The ALC882 series 7.1+2 Channel High Definition Audio codecs with UAA (Universal Audio Architecture), featuring five 24-bit stereo DACs and three 20-bit stereo ADCs, are designed for high performance multimedia PC systems. The ALC882 series incorporates proprietary converter technology to achieve over 100dB Signal-to-Noise ratio playback quality; easily meeting PC2001 requirements and also bringing PC sound quality closer to consumer electronic devices.

The ALC882 series provides 10 channels of DAC that simultaneously support 7.1 sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the Front-Out-Left and Front-Out-Right channels. Flexible mixing, mute, and fine gain control functions provide a complete integrated audio solution for next generation multimedia PCs.
The DACs (with a highest sampling frequency of 192kHz) are applicable for DVD-Audio, previously only implemented in high-end consumer electronics, and now achieved by PCs with the ALC882 series inside. The ALC882 series also integrate three stereo ADCs that can support a microphone array with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technology simultaneously, significantly improving recording quality for conference calls. With this feature (3 stereo ADCs), the ALC882 series can provide high-quality audio using S/PDIF to output analog data, or for multiple-source recording applications.
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.
The ALC882 series supports 16/20/24/32-bit S/PDIF input and output functions for both consumer mode and professional mode, offering easy connection of PCs to high quality consumer electronic products such as AC-3 decoders/speakers, and mini disk devices.
The ALC882 series supports host/soft audio from the Intel ICH6/ICH7 chipset, and also from any other HDA compatible audio controller. With EAX/Direct Sound 3D/I3DL2/A3D compatibility, and excellent software utilities such as Karaoke mode, environment emulation, software equalizer, HRTF 3D positional audio, optional DTS Connect™, and optional Dolby® Digital Live, Home Theatre, and Master Studio programs, the ALC882 series provides an excellent entertainment package and game experience for PC users.
