Videotek® CMN-LA

Loudness Analyzer

Part of the Videotek® Compact Monitor Series, the Videotek® CMN-LA loudness analyzer is a comprehensive audio monitoring tool that makes it easy to confirm compliance with the latest loudness requirements. Loudness and true peak measurements are made to the ITU-R BS.1770-3 standard with five times oversampling. Built-in modes offer quick setup to ARIB TR-B32, ATSC A/85 or EBU R 128 recommendations. Up to five days of loudness data are stored internally and easily retrieved through the USB port or internal web server. Metering of up to 16 channels simultaneously makes for rapid alignment checks.

Integated into the CMN-LA is the TC Electronic® loudness radar meter, which shows loudness on short-terms meters, graphs covering periods from one minute to 24 hours, and numeric display of the long-term center of gravity (average loudness) and consistency (loudness range). The flexible display of the CMN-LA presents data in a format most useful for the job at hand. Use the integrated TC Electronic® loudness radar meter during production, the audio status display during program ingest, and the combination of loudness and true peak meters, numeric display and trend chart for master control monitoring. The chart data can be exported for compliance reporting. Adjustable audio output delay compensates for video monitor processing in critical evaluation suites.

Short mounting depth makes the CMN-LA loudness analyzer ideal in a QC monitoring rack or on the meter bridge of an audio console.
