Многоканальный измеритель громкости LQ-1000https://www.telosalliance.com/Linear
Accepting up to 8 channels of baseband or Dolby® Digital (AC-3) encoded audio via AES or HD/SD-SDI I/O, LQ-1000™ provides simultaneous LKFS loudness measurement for two independent programs (5.1+2) per ITU-R BS.1770-3 and EBU R128 standards. Dolby Digital Plus and Dolby E decoding is optionally available.
The vibrant front-panel display features a large, color-coded numeric loudness value for the primary 5.1-channel program or secondary 2-channel program. The secondary meter can also be used to display loudness values for an internally created Lo/Ro or Lt/Rt downmix.
Additional bar graph meters with adjustable integration times, a loudness histogram to track loudness trends, True Peak readings, and dialnorm and coding information is also displayed.
Additionally, LQ-1000 provides comprehensive logging to a USB or network drive allowing stations to keep records of their loudness measurements.
A rear-panel VGA output allows information to be viewed on an external monitor or multi-viewer.
