The Linear Acoustic LQ-1™ Loudness Meter is a straight-forward yet comprehensive metering solution for accurately measuring loudness in DTV facilities.
Supporting all ITU loudness metering standards, the LQ-1 includes Dolby® Dialogue Intelligence™ to accurately measure the wide dynamic range of long-form content. Input and output signals are displayed alongside the measured LKFS loudness and dialnorm metadata numbers, providing instant verification of loudness compliance.
Audio can be extracted from any pair of an applied HD/SD-SDI signal or from AES, analogue, or TOSLINK™ optical inputs and routed to to the decoding and metering core. Included DVB-ASI mode allows audio to be sourced from a selected PID for decoding and measurement. Decoding for Dolby Digital (AC-3)/Plus/E is standard.
A selectable LoRo or LtRt downmix is available on the rear panel AES and balanced analogue outputs and via a front panel headphone connector. Metadata emulation and Associated Dialogue (AD or Visual Descriptive) mixing can also be auditioned on the downmixed output.
GPI/O for alarms and control is standard, and an SNMP data monitoring package and redundant power supply are optional.
