The 2+2-channel DAC supports two independent stereo sound outputs simultaneously.
The 4-channel ADC integrates two stereo and independent analog sound inputs (multiple streaming). The ALC269 incorporates Realtek converter technology to achieve a 98dB dynamic range playback quality and a 98dB dynamic range recording quality. It meets the current WLP3.10 (Windows Logo Program) and future WLP requirements that become effective from 01 June 2008. The ALC269 also supports stereo digital microphone channels (microphone array) with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technology simultaneously, significantly improving voice quality for PC VoIP applications. As well as basic audio functions, the ALC269 has two independent SPDIF outputs; one could be used to connect a PC to high-quality consumer electronic products such as digital decoders and speakers, the other could provide a dedicated digital output to a HDMI transmitter (common in high end PCs). There are three integrated power amplifiers.
