SDI Interface and Level Magic™ processor

The C8492B is a combination of SDI I/O interface with Level Magic™ loudness management, full dynamics processing, true peak limiting and optional 5.1 Upmix/Downmix.

    Designed for use in C8000 modular systems, the C8492B offers de-embedding/re-embedding of 3G/HD/SD SDI streams and powerful DSP functions. Access to the C8000 frame’s system bus is also provided allowing the transfer and exchange of audio and metadata with other cards in the frame.

    Based on a unique multi-loop control principle, the Level Magic™ algorithm provides adaptive wideband loudness control with exceptionally high audio quality that is free of coloration, pumping, distortion or modulation effects. Level Magic™ combines three major gain changing elements:

    • • Adaptive AGC
    • • Transient Processor
    • • Distortion-free true peak limiter

    • The adaptive dynamic section includes an expander and upward compressor.

    With the optional Upmix license, the unit can be set to detect stereo only content and automatically upmix to 5.1 in order to maintain a constant surround experience. Existing 5.1 content will pass untouched.
