Lancaster, PA (April 5, 2010)--At NAB 2010, Linear Acoustic will introduce the LQ-1000 Loudness Quality Monitor, which is intended for display directly in front of the sound mixer.
The LQ-1000 provides loudness and peak level metering of up to eight channels of 5.1 surround and/or stereo AES or SDI audio per industry-standard ITU-R BS.1770, a requirement for mixing and transmitting in compliance with ATSC Recommended Practice A/85.
Joining the recently introduced Linear Acoustic AERO.qc, the LQ-1000 is also a 2RU device that shares the same display of all critical parameters on a large color OLED display. The LQ-1000 offers metering in a package for studio mixing and plant-wide monitoring, while the AERO.qc provides metering, loudness correction and upmixing; both are aimed for ingest and live sports event metering and control. Deploying the LQ-1000 and AERO.qc throughout a facility maintains a common user interface and display, improving consistency and reducing operational errors.
Mixing to a loudness standard while maintaining production values requires much more than looking at a simple LKFS number. In the LQ-1000, current loudness, target loudness and peak level are clearly indicated with large numbers. In addition, loudness and peak level are displayed simultaneously on a familiar bar graph display. Thumbnail input meters confirm signal presence and level on all channels, and a histogram shows loudness over the duration of the program. Color is used to display the loudness comfort zone: green if within target, blue if too quiet, yellow if getting loud and red if too loud.
Linear Acoustic will offer an LQ-1000/AERO.qc Remote Display/GPI module for universal in-console mounting. The units all provide a VGA output to send the full display to an external monitor or multiviewer. AES outputs provide de-embedded audio for speaker monitoring. GPI/O enables remote control of functions.
