STAC9460 provides variable sample rate conversion, well analog processing. Supported audio sample rates include kHz, 44.1 kHz, kHz, 88.2 kHz, kHz, 176.4 kHz. digital interface communicates standard compatible serial interface digital audio interface. variable sample rate ADC's provide record capability from microphone inputs differential inputs. DAC's operate 24-bit resolution with sample rate based Master Clock. operates 20-bit resolution supplys full 24-bit filter data.The STAC9460 supports three digital audio inputs digital audio output. These digital options provide number advance architectural implementations, with volume controls mute capabilities built directly into codec each individual channel. output volume ranges from with steps. input, input volume ranges from 22.5 with steps. STAC9460 also supports single-line format.The STAC9460 designed primarily support 6-channel audio. True AC-3 playback achieved 6speaker applications taking advantage STAC9460 architecture combining with appropriate processing. This product ideal home theatre, DVD, karaoke, set-top-box applications.
