Orban Optimod Audio Processing
Since the early 70s Orban with it’s renowned Optimod Series has been a leading manufacturer
of AM – FM – DAB – TELEVISION loudness controllers and streaming audio processors...

T

80

he engineering team based in
San Leandro, USA is headed by
the companies Founder Bob Orban.
In 2009 Orban successfully
moved their manufacturing and
Global Sales to Orban Europe
GmbH in Germany.
Orban introduced the first FM
Audio Processor in the mid 70s.
In 1981 they introduced the
very first TV Loudness Controller–
the OPTIMOD TV 8180A–to the
broadcast market selling thousands
around the globe.
Orban have been successfully
engineering and manufacturing
Television Loudness Controllers ,
AM, FM and DAB processors for
more than 40 years in a market
which is constantly evolving.
From the BBC to CNN, many
broadcasters rely on the OPTIMOD
to ensure that their audio
quality is perfect.
The Optimod TV-8685 is Orban’s
second-generation surround/2.0
processor. In addition to the effective
automatic loudness control of its
predecessor, the TV-8685 offers
new input/output capabilities that
include support for SDI and HD-SDI
and for Dolby E.
The built-in, Orban-developed
Optimix upmixer provides automatic
and completely convincing stereoto-surround upmixing, with a
solid, discrete centre channel.
Unlike technology derived from
consumer matrix decoders,
there is no program-dependent
directional pumping of sound
sources. Unique to this technology
is extremely robust centre channel
phase/skew correction that never
causes negative side effects. It is
invaluable for older material that
was originally recorded on analogue
tape. Optimix’s output downmixes
to stereo flawlessly, and the skew
correction often makes the downmix
sound better than the original stereo!

In the toughest competitive
environment ever, a winning strategy
includes OPTIMOD-FM 8600

Orban Television audio processing–sound that keeps audiences satisfied

There are large, important
subjective differences between
Optimod and competing processors.
Optimod has a unique architecture
that processes the centre
channel to correct spectral and
loudness balance problems that
compromise dialogue intelligibility
in ill-considered mixes. Orban
report hearing feedback from
broadcasters who have suffered
increased viewer complaints about
unintelligible dialogue after installing
an alternative processor. The TV8685 offers flawless loudness
control, it also improves dialogue
intelligibility and maintains a full,
natural sound without exaggerated
“esses,” hollowed-out midrange,
or obtrusive pumping of ambient
sound. Thanks to the Optimix
upmixer, which cleanly extracts
dialogue from stereo sources, the
TV-8685 can even improve dialogue
from these sources! These factors
are why the TV-8685’s subjective
audio quality wins every serious
shoot-out when compared to
its competition.
The TV-8685 is dialnorm-aware.
Loudness control is excellent when
measured by the ITU BS.1770-2
and EBU R-128 standards or by the
TV-8685’s built-in CBS Loudness
Meters, allowing stations to comply
effortlessly with the requirements
of the CALM act. An included
logging application allows
time-stamped

indications of the TV-8685’s builtin BS.1770-2 short-term and
integrated loudness meters to be
written to a Windows PC’s local or
network storage.
OPTIMOD-FM 8600 is Orban’s
flagship processor. Featuring
versatile five-band and two-band
processing for both analogue FM
transmission and digital media, the
FM-8600 provides the industry’s
most consistent sound, track-totrack and source-to-source. This
consistency allows you to create a
sonic signature for your station with
the assurance that your signature
will stay locked in, uniquely
branding your sound.
Dramatically improved peak
limiter technology decreases
distortion while increasing transient
punch and high frequency power
handling capacity. Compared to
the FM-channel peak limiter in
OPTIMOD-FM 8500, the new peak
limiter typically provides 2.5 to 3
dB more power at high frequencies,
which minimises audible HF loss
caused by pre-emphasis limiting.
Drums and percussion cut through
the mix. Highs are airy. “Problem
material” that used to cause audible
distortion is handled cleanly.
While this design offers about
the same loudness as FM-8500
processing, its main goal is to make
FM analogue broadcasts more
competitive with the cleanliness,
punch, and open high frequencies of
the digital media against which FM
analogue transmissions now battle.
The FM loudness wars represent
20th-century thinking; in the 21st
century, the new competition is
digital media. Thanks to its fresh,
crisp sound, the FM-8600 helps
level the playing field between
analogue FM and its ever more
aggressive digital-only competitors.
The FM-8600 offers FM-8500style processing too. This allows
broadcasters to run favourite
FM-8500 presets if they wish.
Because the input/output delay of
the new peak limiter is too long to

permit talent to monitor off-air on
headphones, FM-8500 processing
is useful for remotes and outside
broadcasts where off-air headphone
monitoring is desired and the FM8600’s low-delay monitor output
cannot be brought to the talent.
The FM-8600 provides stereo
enhancement, equalisation, AGC,
multiband compression, low-IM
peak limiting, stereo encoding, and
composite limiting–everything that
even the most competitive major
market station needs to stand
out on the dial.
Processing for digital media like
netcasts and HD Radio is supplied
standard. The FM and digital media
processing paths split after the
FM-8600’s stereo enhancer and
AGC. There are two equalisers,
multiband compressors and peak
limiters, allowing the analogue FM
and digital media processing to be
optimised separately. The bottom
line? Processing that optimises the
sound of your FM channel while
punching remarkably crisp, clean,
CD-like audio through to your digital
channel audience.
More than 20 excellent sounding,
format specific factory presets get
you started. You’ll find all of your
favorite FM-8500 presets, plus
new “MX” presets designed by
Bob Orban and Greg Ogonowski
to exploit the exciting possibilities
inherent in the FM-8600’s new peak
limiter technology.
Although the factory presets are
fully competent “out of the box”, you
can customise them with easy oneknob less-more control or with more
than 60 advanced controls with
versatility that will satisfy even the
most finicky on-air sound designer.
New for the FM-8600 is the ability
to apply MPX power gain reduction
after the clippers so that the texture
of the processing can include more
“clipper sound” when desired.
Regardless of how you adjust the
multiplex power controller, you can
be sure that you will always meet the
BS 412 requirements flawlessly.
