Linear Acoustic® featured its newest audio/loudness manager for digital television, AERO.2000™, at CABSAT 2013, demonstrated by the AVC Group in Hall 7, Stand C7-40.

Built upon the highly successful AERO.air™, AERO.2000 includes AEROMAX® loudness control with patented Linear Acoustic Intelligent Dynamics™ hybrid metadata processing for proven loudness control, industry-standard upmixing via UPMAX® II with fulltime downmix, optional Dolby® encoding/decoding and Nielsen® Watermarking, and extensive I/O features.

Support for up to 16 audio channels in two independent instances - 5.1+2+Local and 2+2+Local – provides a high degree of program configuration flexibility, while ITU-R BS.1770-3 simplifies loudness monitoring for all programs. Professional audio metadata can be applied to minimize processing and control functions, or traditional processing and upmixing can be employed.

A comprehensive TCP/IP remote control is included, giving users the ability to set up, adjust, and display all AERO.2000 parameters including loudness metering, Dolby Digital (AC-3) statistics, and even return audio (network speed permitting). The software can connect to multiple AERO.2000 units simultaneously, a major convenience for anyone who oversees multiple stations in different locations. A built-in http server provides access to metering logs.

AERO.2000 includes AES and HD/SD-SDI I/O, compensating video delay, and redundant power supplies as standard features. Dolby Digital/Plus encoding, Dolby Digital/E decoding, and Nielsen Watermarking are optional.

Other Linear Acoustic products on display at CABSAT will include:

• AERO.1000™ Audio/Loudness Platform, with up to 64 channels of AEROMAX loudness control, UPMAX upmixing/downmixing, and optional Dolby encoding/decoding and Nielsen Watermarking for all channels
