What audio formats can the iScan VP20 support?
The audio section of the iScan VP20 supports S/PDIF formatted audio with sample rates ranging from 24kHz to 192kHz. It will likely handle sample rates beyond this range, but is only guaranteed to support sample rates within this range. The iScan VP20 will also pass compressed digital audio (e.g. Dolby Digital or DTS) provided the audio bitstream has been properly formatted for S/PDIF (IEC60958 or EIAJ-CP1201 standard) transmission by the digital audio source (according to international standard IEC61937). The iScan VP20 does not alter the sample rate, format, or content of the digital audio whatsoever; it merely inserts a programmable delay into the transmission path. Users should take care to use proper digital audio cables in order to guarantee valid audio reception and re-transmission. Both coax and optical cables should have high-quality, positive mating connectors at both ends. Coax cables should have a 75-ohm characteristic impedance.
