OPERATION ORBAN MODEL 9400
NEWS uses a fast multiband release time. Because of this, the unit adapts quickly to
different program material, providing excellent source-to-source consistency. This
“automatic equalization” action of the multiband compressor has been adjusted to
produce less bass than in the GEN(ERAL) presets, and the gating threshold is set
considerably higher. This maximizes voice intelligibility, including low-quality sources
like telephone. The high gating threshold resists noise pumping even with noisy
material.
NEWS + NR is identical to the News preset except that the Dynamic Noise Reduction
function is also activated, producing even more noise reduction on moderately noisy
program material. However, the Dynamic Noise Reduction function can produce
audible side effects that include noise pumping on very noisy material and a subtle loss
of crispness on high-quality voice. So you should listen carefully to decide if it is
preferable to News for your situation.
TALK is similar to the News preset but is tailored for live microphone and telephone
sources with less consideration given to the handling of actualities.
SPORTS is based on the Fast multiband release time. It is intended for play-by-play
sports programming, where crowd noise is part of the mix. Compared to NEWS, the
AGC is operated with a slower release time to avoid pumping up crowd noise as much
as the News preset would. Yet the Fast multiband release time still provides excellent
consistency, intelligibility, and loudness. This preset uses the Dynamic Noise Reduction
function to reduce noise pump-up.
FINE ARTS is based on the Slow multiband release time. It is designed for classical and
jazz programming where an open, unprocessed sound is more desirable than the last
bit of loudness. Unlike the other factory presets, the FINE ARTS LESS-MORE curves are
designed to produce more compression as they are advanced, but to create only a
modest increase in clipping distortion. So setting LESS-MORE higher will mostly
increase the level of quiet passages instead of increasing the loudness of loud passages
in the source material.
MUSIC MEDIUM is based on the Medium-Slow multiband release time. It is designed
