Introduction
The Videotek® LLM-1770 loudness logger and monitor is a compact 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.
Included settings match EBU R 128, ARIB TR-B32, and ATSC A/85 recommendations.
Internal memory stores five days of loudness and alarm data. Logs can be exported via
Ethernet or USB. Remote control and monitoring can be performed from any web browser.
The LLM-1770 comes with four AES inputs and has options for Dolby decode and SDI
embedded from SD, HD or 3 Gb/s sources. There is a headphone jack for local confidence
monitoring. A standard LLM-1770 with the Dolby decode option installed is considered an
LLM-1770-D.
The LLM-1770 features audio alarm capabilities, including peak audio reporting. Real-time
signal alarms have user adjustable limits. Remote interfaces include 10/100Base-T Ethernet
and plug and play USB port (supporting export of log and alarm files as well as flash
updates). The LLM-1770 has all-digital architecture; therefore, no periodic calibration is
required.
The LLM-1770 seamlessly integrates into any broadcast, post-production, satellite or cable
facility, and is the ultimate choice for quality control, troubleshooting, or compliance
checking applications.
