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

Product details•

The The basic CMN-LA unit operates with 3G/HD/SD-SDI embedded audio sources,
with a hardware option for eight AES inputs, four AES outputs and eight analog outputs.
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. The Dolby® decoder requires the AES I/O option. The AES option also includes
an LTC input for time stamping of log entries.

The CMN-LA also includes internal speakers and a front-panel headphone jack for
source confirmation. A mixdown mode can be applied to the headphone output when
using discreet sources. The mixdown parameters are taken from VANC medatada if
present, otherwise internal menu settings are used.

with the latest loudness requirements. Loudness and true peak measurements
are made to the ITU-R BS.1770 standard with five times oversampling. Built-in
modes offer quick setup to 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
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.
