Linear Acoustic now shipping AEROMAX-5.1 with Built-in Dolby Digital Encoding
Linear Acoustic, announced that it is now shipping its
next-generation AEROMAX 5.1 10-channel TV audio processor. A comprehensive
solution created to meet the challenges of advanced DTV delivery, the
AEROMAX-5.1 features a loudness controller, upmixer, and metadata manager. The processor
accepts 5.1 network audio, two-channel local audio, and digital or analog
auxiliary/EAS stereo audio. Optional HD-SDI audio and metadata input and
internal Dolby Digital (AC-3) or Coding Technologies aacPlus (MPEG-4 HE AAC)
encoding are also available.
“We’ve designed the AEROMAX-5.1 to help broadcasters transition to digital
as smoothly as possible,” said Tim Carroll, president and founder of
Linear Acoustic. “The processing capabilities of the AEROMAX-5.1 make it
easier to deliver the consistent and compelling surround sound for television
that viewers expect.”
The AEROMAX-5.1 is based on the overwhelming success of the Linear Acoustic
OCTiMAX 5.1 digital television audio processor. It combines network-proven
dynamics processing algorithms designed by noted processing guru Leif Claesson
with upMAX surround sound upmixing, and extensive local features such as a full-time
two-channel downmix to feed legacy analog paths.
The system’s built-in AutoMAX processing fixes two-channel audio that is
broadcast wrongly signaled as 5.1 channels. This eliminates the annoying image
shift that occurs as dialogue moves from the left and right front speakers to
the center speaker when programs transition between two and 5.1 channels.
AEROMAX-5.1 takes advantage of metadata for the proper processing of audio and
to control upmixing and other features offered by the unit. Network and local
audio can be handled separately, with metadata used alone or in combination
with dynamic range processing, to ensure a high-quality sound experience true
to the original audio source.
With AEROMAX-5.1’s new features, broadcasters can save time, money, and space
while continuing to deliver quality audio. Options such as an HD-SDI video
input and internal Dolby Digital (AC-3) or Coding Technologies aacPlus (MPEG-4
HE AAC) 5.1-channel encoding reduce the amount of equipment needed, while the
redundant power supply allows smooth and reliable integration into typical
The complete range of Linear Acoustic solutions includes the
AEROMAX, StreamStacker-HD, LAMBDA, and MetaMAX products. More information about
