High-quality, multipurpose stereo OPTIMOD —
Three Processors in One!
1

2
The 6300 is a high-quality,
multipurpose stereo audio
processor for digital radio,
digital television, netcasts,
STL protection, audio production
and digital mastering.

3
With 20 kHz audio
bandwidth and 48 kHz
internal sample rate,
the 6300 replaces Orban's
popular OPTIMOD-DAB 6200
audio processor while offering
improved processing algorithms
and more flexibility.

4
For video applications,
broadcasters can activate the
6300's CBS Loudness Controller
to prevent audience irritation
and tune-outs caused by
loud commercials.

5
New for version 2.0 is a CBS
Loudness Meter and full support
for Dolby Digital dialnorm
metadata, as well as presets that
allow the 6300 to process for
analog television channels.

The 6300 incorporates
Orban’s PreCode technology,
which pre-processes audio to
minimize audible artifacts in
low bitrates codecs such as the
iBiquity HDC codec used in
HD Radio.
Several of the 6300’s presets
exploit this technology to
provide “plug and play”
processing at low bitrates.

The 6300’s AGC uses the
same dual-band, windowgated,
matrix technology as
the AGCs in Orban’s 2300,
5300, 8300, 8382, 8500,
9300 and 9400 OPTIMODs,
so it can substitute accurately
for the AGCs in these devices.

8
Because the 6300’s AGC is
more advanced than the
AGCs in Orban’s 2200, 8200
and 9200 OPTIMOD units,
the 6300 can upgrade the
performance of these older
products when substituted
their AGCs.

Three processors in one:
Versatile routing lets you use
the 6300 to simultaneously
protect an STL, process for a
netcast or digital radio broadcast
and provide a low-delay talent
headphone feed.

The 6300 has two analog inputs
and outputs.
There are two digital outputs
and one stereo input.
The 6300’s outputs can be
independently configured to
emit the output of the AGC or
the output of the multiband
compressor/ limiter.
10

Other important features include
soft knee and compression ratio
controls for each of the bands in
the multiband compressor/limiter.
This allows mastering and
production engineers to apply
very subtle multiband
compression while retaining as
much of the original source’s
dynamics as desired.
11

48 kHz internal sample rate
provides 6 dB lower filter noise
and non-linearity than 96 kHz
systems; bandwidth is selectable
in steps between 10 and 20 kHz.
Ethernet, RS232 serial and GPI
remote control; includes full
featured PC Remote software.
12

A 6300 can simultaneously:
Drive an STL (flat, or preemphasized
at 50 µs or 75 µs)
with a peak-limited output
from the 6300’s AGC.
Provide a fully processed digital
radio/netcast feed with two-band
or five-band multiband
compression and peak limiting.
Provide a low-delay, multibandcompressed
headphone feed
for talent.
13

Three levels of control over
your sound:
Factory processing presets
named for your format, easy,
single-knob LESS-MORE control
of processing within each
preset and FULL CONTROL
for versatile customization
of your sound.
14

Three levels of control over
your sound:
Phase-linear signal path for
maximum transparency.
Digital I/O: 96, 88.1, 48, 44.1
and 32 kHz input,
automatically selected;
96, 88.1, 48, 44.1 or 32 kHz
output.
15

The 6300 is ideal for mastering
applications:
New in OPTIMOD processors, the
6300’s KNEE and RATIO controls
for each band in the multiband
compressor make the 6300 a
versatile mastering compressor.

17
Whether you’re looking for
loudness or transparency,
the 6300’s low-IM look-ahead
limiter is competitive with
the best dedicated
mastering limiters.

Double-precision (48-bit)
crossover filters and equalizers
have superbly low noise and
distortion.
The new CBS Loudness Meter
indicates subjective loudness
and can help ensure consistent
loudness from track to track.
18

In television, video and other
sound-for-picture applications:
The 6300’s CBS Loudness
Controller tames loud
commercials to prevent viewer
annoyance and tune-outs.
Video-specific presets make
setup easy.
Defeatable dynamic noise
reduction is useful for news and
play-by-play sports.
19

In television, video and other
sound-for-picture applications:
Sophisticated gating of the AGC
and multiband compressor
prevents noise pumping.
The 6300 can be used to
process for analog TV
transmissions, providing the
same loudness as Orban’s 8382
OPTIMOD-TV. You can buy a
6300 for analog TV today
knowing that it will work for
DTV tomorrow.
20

In television, video and other
sound-for-picture applications:
The 6300 is Dolby Digital ®
dialnorm-aware. Tell it what value
of dialnorm you are transmitting
to your audience, use a “TVxxx”
preset, and your transmission’s
loudness will always be correct.
The 6300’s CBS Loudness Meter
indicates subjective loudness and
is always accurately calibrated to
the dialnorm value you specify.
21

Six levels of password-based
security.
Front panel LED metering of
left and right input and gain
reduction levels.
Compact one rack unit design.
22

The 6300 employs mastering
quality equalizers and crossover
filters throughout.
The three-band parametric
equalizer’s curves accurate
emulate an analog parametric
equalizer, while a parametric
low-frequency shelving equalizer
with 6, 12 or 18 dB/octave slopes
allows a user to add bass punch
without muddiness.

Not only will the 6300 offer
higher quality in tradition 6200 applications,
but its versatile routing,
new features and immaculate
signal path will open up
new applications and markets
in broadcast and professional audio.
