Lancaster, PA (February 26, 2009)–NBC affiliate KSL 5 TV in Salt Lake City is using Linear Acoustic’s AERO.air 10-channel TV audio processor to control audio levels and to create surround sound from the stereo-only components of its broadcasts.
“Like many broadcasters, we experienced a lot of problems with varying audio levels for network and local programming, particularly during playout of news and sports,” said Brent Robinson, chief engineer at KSL 5 TV.
“We needed a way to address this discrepancy in loudness levels and even out audio volume, and the Linear Acoustic AERO.air has proven to be a wonderful solution. We noticed a significant difference immediately upon implementing the processor, and we haven’t received any comments about disparities in audio loudness since that day.”
AERO.air is equipped with multiple loudness controllers, dual upmixers and metadata management, as well as full-time two-channel downmixing to support legacy stereo or analog paths. Built-in AutoMAX-II processing detects incoming audio and automatically upmixes only when necessary, producing a full-time 5.1 channel output. The processor accepts 5.1 channel network audio, two-channel local audio, SAP/DVS, and digital or analog auxiliary/EAS audio for processing. Available options include HD/SD-SDI input for de-embedding any of the possible 16 audio channels and vertical ancillary (VANC) metadata, internal 5.1+2 dual Dolby Digital (AC-3) encoders, and CrowdControl dialogue protection.
