The ALC892 also features secondary SPDIF-OUT output and converter to transport digital audio output to a High Definition Media Interface (HDMI) transmitter. Support for 16/20/24-bit SPDIF input and output with up to 192kHz sample rate offers easy connection of PCs to consumer electronic products such as digital decoders and speakers. All analog I/Os can be re-tasked according to user definitions. 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.Īll analog I/O are input and output capable, and headphone amplifiers are also integrated at three analog output ports (port-D/port-E/port-F). The ALC892 provides ten DAC channels that simultaneously support 7.1 channel sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo outputs. The ALC892-CG/ALC892-DTS-CG is a high-performance multi-channel High Definition Audio Codec with Realtek proprietary 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.
