Product Description

Accepting up to 8 channels of baseband or Dolby® Digital (AC-3), Dolby Digital Plus, or Dolby E encoded audio via AES or HD/SD-SDI I/O, LQ-1000 provides simultaneous LKFS loudness measurements for two independent programs (5.1+2) plus a downmix per ITU-R BS.1770-3 and EBU R128 standards.

Color-coded loudness values and bar graph meters with adjustable integration times are easily visible on the vibrant front-panel display along with a loudness histogram, True Peak readings, and dialnorm and coding metadata values.

Individual loudness logs for both the primary and secondary audio inputs covering the past 24 hours, 48 hours, 7 days, and a user-defined time period are available via the built-in HTTP server 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 while full IP remote control support including metering displays is available via the provided NfRemote PC application. Many existing units can be upgraded to support remote connectivity – please contact Linear Acoustic for details.
