4/8/16 channels DSP with SDI & system-bus I/O
The C8492 is a variation of the next generation module platform that combines a 16 channel
3G/HD/SD-SDI embedder / de-embedder with a 16ch DSP. For a start it can be treated as the successor
of the C8491. The C8492 can be purchased as a four / eight or 16 channel processor (C8492-x)
with surround option (C8492-xS) or without it.
It may also be purchased with c8k audio bus access and is then called C8492B.
Without the SDI piggyback board it is called C8092 and offers a 16 channel c8k audio processor that is
beyond a successor of the C8086+ since it combines LevelMagic loudness control with stereo and/or
surround fail over functions inluding 5.1 downmix and 5.1 upmix. For details of versions and pricing pls.
