Linear Acoustic(R) Announces LQ-1(TM)

Loudness Meter With Full Decoding and Dolby(R) Dialogue Intelligence(TM)

LANCASTER, Pa. -- April 16, 2012 -- Linear Acoustic(R) today introduced the LQ-1(TM) loudness meter, a straightforward and accurate metering solution for measuring loudness in digital television facilities.

The LQ-1 supports all ITU, ATSC, and EBU loudness metering standards, and it includes Dolby(R) Dialogue Intelligence(TM) to measure the wide dynamic range of long-form content more accurately. Input and output signals are displayed alongside the ITU-R BS.1770-measured LKFS loudness and dialnorm metadata to provide instant verification of loudness compliance.

"Having a meter in place that supports the most popular audio, metering, and I/O standards is a basic minimum," said Tim Carroll, President and Founder of Linear Acoustic, "but having a meter that delivers repeatable and realistic measurements regardless of the content or operator skill is now critically important -- and the LQ-1 with Dolby Dialogue Intelligence delivers."

Comprehensive SDI, AES, analog, and optional DVB-ASI inputs are followed by decoding for PCM, Dolby Digital (AC-3), Dolby Digital Plus, HE-AAC (v1 + v2), Dolby E, and MPEG-I Layer II audio. The LQ-1 provides a selectable LtRt or LoRo downmix via the AES, analog, and headphone outputs and supports metadata emulation and auditioning Associated Dialogue (AD) mixing.

GPI/O is standard along with an internal auto-ranging power supply. SNMP and a redundant external power supply are optional. Like all Linear Acoustic products, the LQ-1 is designed and assembled in the USA and is backed by world-class expertise and support.
