The MC-1RU version LCM-KRT-1CH KARMAudioRT Loudness Control Card from Wohler provides automatic control of perceptual loudness, continuously monitors embedded stereo or multi-channel surround audio loudness, and seamlessly adjusts system gain across all channels to maximize impact while achieving the target loudness and preserving the spatial imaging.

The LCM-KRT-1CH makes it easy to comply with emerging loudness practices such as ATSC A/85:2009/2011 (as required by C.A.L.M Act), EBU R 128-2011 and short-term peak loudness. It provides 8x over-sampling, true-peak estimation, and instantaneous correction to all stereo or multi-channel surround channels to ensure per channel peak-program level limits are adhered to.

The MC-1RU modular chassis enclosure can to accomodate the LCM-KRT-1CH. This self-contained 1RU cabinet holds up to two cards and comes standard with redundant power supplies.

Audio
2 Audio programs per video stream (each audio program can be up to 5.1 channels)
2 GPI-controlled presets per program
Functions
Automatically compresses/clips excessively loud AES audio embedded on an SDI stream
Computes loudness on selected audio with ITU-R BS.1770 loudness and true peak algorithms
Primary audio program and SAP have concurrent, independently con? gurable loudness correction
Alternate con? guration for both primary and SAP are selectable via switch closure on GPI
Control
Graphical user interface
User-defined loudness target level (LKFS)
Full control over loudness correction parameters: Attack, Release, Integration Time (Window), Peak Clip, Peak Knee
Primary and SAP audio correction bypassable via switch closure on GPI
Selection of any six embedded audio channels in the SDI stream for each audio program
Inclusion/exclusion of any the selected channels in the loudness calculation
Communications
1 x RJ-45 jack (labeled 10/100 Ethernet) provides 10Base-T or 100Base-T Ethernet connectivity (provides serial communications with terminal console via 2 available Virtual Serial Ports)
1 x RJ-45 jack (labeled RS-232/GPIO) provides RS-232 serial communications with terminal console over Virtual Serial Port)
