The ALC880 and ALC880D 7.1 Channel High Definition Audio codecs with UAA (Universal Audio Architecture), featuring four 24-bit two-channel DACs and three stereo 20-bit ADCs, are designed for high performance multimedia PC systems. The ALC880(D) incorporates proprietary converter technology to achieve 100dB sound quality; easily meeting PC2001 requirements and also bringing PC sound quality closer to consumer electronic devices.
The ALC880(D) provides 7.1 output channels, along with flexible mixing, mute, and fine gain control functions to provide a complete integrated audio solution for PCs. The DACs (with a highest sampling frequency of 192kHz) and Realtek proprietary hardware content protection are applicable for DVD-Audio, previously only implemented in high-end consumer electronics, but now achieved by PCs with the ALC880(D) inside. The ALC880(D) is also the only High Definition Audio codec to 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 unique feature (3 stereo ADCs), the ALC880(D) can provide high-quality audio using S/PDIF to output analog data, or for multiple-source recording applications.
Realtek's proprietary impedance sensing and jack detect techniques allow device loads on inputs and outputs to be auto-detected. 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 (Universal Audio Jack®).
The ALC880(D) supports 32-bit S/PDIF input and output functions and a sampling rate of up to 96kHz, offering easy connection of PCs to high quality consumer electronic products such as AC-3 decoders/speakers, and mini disk devices.
The ALC880(D) supports host/soft audio from the Intel ICH6 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® Digital Live, the ALC880(D) provides an excellent entertainment package and game experience for PC users.
