Linear Acoustic AERO.ASI User Guide Factory Presets
Net 5B Limit
Net 5B Limit applies a final polish to an already consistent network program prior to distribution. A
combination of TV 5B Light and ITU 5B Loudness Limit, this preset has a very slow input AGC, and
a lighter multiband AGC. It preserves microdynamics and pulls the low-level information up slightly
while protecting against long-term loudness shifts.
Protection Limit
Protection Limit sets all processing to unity gain and leaves only look-ahead peak limiters in the signal
path. The master output level is set to 0 dB, so applied signals get a unity gain path through the processor.
Reference Settings
This preset offers standard processing test settings that match TV 5B Gen.
Sports 5B Gen
Sports 5-Band General provides medium processing that features quick response with minimal back-
ground pumping. It keeps dialogue present and audible, even in rich surround mixes.
TV 4B Gen
Television 4-Band General is essentially the same as TV 5B Gen (below) with four audio bands. This
keeps all other settings the same, lessens the density and impact on dialogue, and results in more open
sounding audio, albeit with less short-term dynamic loudness control.
TV 5B Gen (Default)
Television 5-Band General is the factory default preset and also the most commonly used. It provides
moderate dynamic range processing, and is appropriate for all content types.
TV 5B Hvy
Although Television 5-Band Heavy is similar to TV 5B Gen, its multiband compression ratio is higher,
which creates a denser but less dynamic sound useful for systems with smaller speakers.
TV 5B Light
Although Television 5-Band Light is similar to TV 5B Gen, its multiband compression ratio is lower
(2:1) for more subtle action. This is an excellent preset for content known to be consistent that needs
just a bit of spectral polish. Note that this preset allows more variations without correction, but for
already consistent content, this is not an issue.
TV 5B Loud
Television 5-Band Loud is similar to TV 5B Hvy, but louder and punchier.
