Part of the Videotek Compact Monitor Series, the 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 standard with five times oversampling. 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.
The basic CMN-LA unit operates with AES audio sources, with an option for de-embedding audio from SDI video up to 3 Gb/s. Eight AES inputs, four AES outputs and eightanalog outputs come standard. The analog outputs are meant to drive high impedance loads.
Dolby decoding is a hardware option available at the time of order, or for field installation. Embedded audio from SDI inputs is a keyed upgrade available at time of order, or for field installation. The SDI inputs can be ordered as SD only, HD/SD or 3G/HD/SD. SD can be field upgraded to HD or 3 Gb/s, and HD can be field upgraded to 3 Gb/s. The CMN-LA also includes analog outputs to drive monitor speakers and a front-panel headphone jack.
