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...

O

rban is proud to have been
successfully engineering and
manufacturing Television Loudness
Controllers, AM, FM, Digital Radio, and
Internet Radio processors for more
than 45 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.
OPTIMOD-FM 8700i
In
the
toughest
competitive
environment ever, a winning strategy
includes OPTIMOD-FM 8700i with
Xponential Loudness™.
OPTIMOD-FM 8700i is Orban's
flagship processor. Featuring versatile
five-band and two-band processing
for both analogue FM transmission
and digital media, the 8700i provides
the industry's most consistent sound,
track-to-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"

Orban's Flagship
processor the
Optimod8700i

Exclusive Xponential Loudness™
processing exploits psychoacoustics
to revive music that has been
"hypercompressed" in mastering and/
or passed through lossy compression,
like MP3. It's like an audio magnifying
glass that brings out hidden detail,
clarifying audio while reducing
listening fatigue and inspiring
audiences to listen longer.
Sound Quality
The 8700i builds on 8600 V4's
outstanding reliability and industryleading sound quality. It adds Dante
AES67 Audio-over-IP connectivity
and a hot-swappable, dual-redundant
power supply with automatic failover.
A digital MPX output using a 192 kHz
AES3 connection is now standard, as
are two digitised SCA inputs. A new
programme-adaptive
subharmonic
synthesiser ensures punchy bass, even
with older programme material.
An important feature is a phase
skew corrector/multipath mitigator
that prevents high-frequency loss
when receivers blend to mono and
minimises energy in the stereo
sub-channel without compromising
separation.
The phase skew corrector uses
a
proprietary
multidimensional
processing programme algorithm
that can simultaneously correct
several unequal delay errors, such
as multiple-microphone pickup of
a single instrument in the original
recording session combined with

left/right gap skew-in an analogue
mixdown recorder.
In addition to subharmonic synthesis
and phase skew correction, the 8700i
provides stereo enhancement, HF
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.
MX Peak Limiter
Orban's exclusive MX peak limiter
technology decreases distortion while
increasing transient punch and high
frequency power handling capacity.
Compared to the 8500's limiter, the
MX limiter typically provides 2.5 to
3dB 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.
FM Loudness
The 8700i's 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 crisp, punchy sound,
the 8700i helps level the playing
field between analogue FM and its
ever more aggressive digital-only
competitors.
Processing Presets
The 8700i offers 8500-style
processing presets too. Because the
input/output delay of the MX peak
limiter is too long to permit talent
to monitor off-air on headphones,
8500-style is useful for remotes and
outside broadcasts where off-air
headphone monitoring is desired and
the 8700i's low-delay monitor output
cannot be brought to the talent.
The low-delay headphone monitor
uses a separate processing chain
(based on the 8700i Ultra-LowLatency processing structure) that
allows you to dial in the precise
amount of "FM clipper sound" that
your talent prefers.

Orban Milestones...
In 2009 Orban successfully moved
its manufacturing and global sales to
Orban Europe GmbH in Germany. In
1981 Orban introduced the very first
TV Loudness Controller the OPTIMOD
TV 8180A of which the company sold
thousands to broadcasters around the
globe. Orban introduced the very first
FM Audio Processor in the mid-'70's.
The engineering team based in
San Leandro, USA is headed by the
company founder Bob Orban.
