Orban Optimod Audio Processing
Since the early 70's Orban with its renowned OPTIMOD Series has been the
leading manufacturer of AM - FM - DAB - TELEVISION Loudness Controllers
and Streaming Audio Processors...

rban's
engineering
team
based in San Leandro, USA is
headed by the company's Founder
Bob Orban.
In 2009, Orban successfully
moved its manufacturing and
Global Sales to Orban Europe
GmbH in Germany.
Orban introduced the first FM
Audio Processor in the mid-70s.
In 1981 Orban introduced the
very first TV Loudness Controller
the OPTIMOD TV 8180A of which
thousands have been sold to
broadcasters around the globe.
Orban are proud to 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.
Orban
Television
Audio
Processing
-
sound
that
keeps audiences satisfied: 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 Dolby E and
Dolby AC3.
The built-in, Orban-developed
Optimix
upmixer
provides
automatic
and
completely
convincing
stereo-to-surround
upmixing, with a solid, discrete
centre channel. Unlike technology
derived from consumer matrix
decoders, there is no programmedependent 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!
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
illconsidered mixes. We have heard
reports from broadcasters who
have suffered increased viewer
complaints about unintelligible
dialogue after installing the leading
competitive processor. The TV8685 is exactly the opposite - in
addition to 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 TV8685'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.17702 and EBU R-128 standards or
by the TV-8685's built-in CBS
Loudness
Meters,
allowing
stations to comply effortlessly with

Orban's OPTIMOD-FM 8600 provides versatile five-band and two-band
processing for both analogue and digital media.

the requirements of the CALM act.
An included logging application
allows time-stamped indications
of the TV-8685's built-in BS.17702 short-term and integrated
loudness meters to be written to
a Windows PC's local or network
storage.
In the toughest competitive
environment ever, a winning
strategy includes OPTIMOD-FM
8600: Orban's flagship processor,
the OPTIMOD-FM 8600, features
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, trackto-track 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.
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 FM8600 helps level the playing field
between analogue FM and its
ever more aggressive digital-only
competitors.
More than 20 excellent sounding,
format specific factory presets get
you started.
When you decide to use the
8600's superb DSP-based stereo
encoder and composite limiter,
be assured that they deliver an
FM analogue signal that is always
immaculately clean
and perfectly peak
limited, with full
spectral protection
of
subcarriers
and
RDS/RBDS
regardless
of
the amount of
composite limiting.

Orban's OPTIMOD TV-8685 offers effective automatic loudness control and new input/output capabilities.

We haven't forgotten pure
analogue FM broadcasters. An
8600FM model without digital
radio processing is available at
lower cost.
Now, the FM processing chain in
the 8600 offers an ITU-R BS.17702 Loudness Meter and Safety
Limiter for use in countries that
enforce a BS.1770 loudness limit
on FM radio broadcasts.
For our European customers,
a second generation ITU BS
412 multiplex power controller
yields the best possible coverage
while flawlessly complying with
the regulations. You can adjust
it to maximise loudness within
the constraints of the BS 412
standard or to produce less gain
change at the expense of slightly
lower loudness. The 8600 applies
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.
A
loop-through
connection
is provided to enable a ratings
encoder (such as Arbitron) to be
inserted between the output of the
audio processing and the input to
the stereo encoder.
Analogue Fallback to Digital
control that allows Silence Sense
to switch the active input from
Analogue to Digital if silence is
detected in the analogue input
signal but not on the digital input
signal. This function works vice
versa as well as on both analogue
and digital AES input. The silence
sense parameters apply to both
simultaneously and both detectors
are available to drive the 8600's
tally outputs and for sending
SNMP Traps/Alerts.
