The ALC898 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. Two stereo ADCs and one stereo digital microphone converter are integrated and can support a microphone array with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technologies. The ALC898 incorporates Realtek proprietary converter technology to achieve 110dB Signal-to-Noise ratio (SNR) playback (DAC) quality and 104dB SNR recording (ADC) quality, and is designed for Windows Vista premium desktop and laptop systems.

All analog I/O are input and output capable, and headphone amplifiers are also integrated at eight analog output ports (port-A to port-H). All analog I/Os can be re-tasked according to user’s definitions.
Support for 16/20/24-bit S/PDIF input and output with up to 192kHz sample rate offers easy connection of PCs to consumer electronic products such as digital decoders and speakers. The ALC898 features secondary S/PDIF-OUT output and converter that transport digital audio output to a High Definition Media Interface (HDMI) transmitter. [ … ]
