Version 2.0 Software
OPTIMOD-FM 8300 is Orban's mid-priced
processor with many of the sound processing
features that were previously available only to
8400 or 8500 owners.

OPTIMOD-FM 8300
User-Friendly Interface
An LCD and full-time LED meters make setup,
adjustment and programming of OPTIMOD-FM 8300
easy — you can always see the metering while you’re
adjusting the processor.

OPTIMOD-FM 8300
Version 2.0 Software
•
4
Adds netcast/digital radio/HD processing for the
5-Band and 2-Band modes. This processing is
created by driving the output of the 5-band or
2-band compressor into a look-ahead limiter.
The AES3 output can be switched to emit
the HD-processed signal.

Version 2.0 Software
5
•
Adds a three-mode bass clipper
(Soft, Medium and Hard).
•
Adds look-ahead to 5-band compressor with the
option to turn it on, turn it off, or have it
automatically switched on for speech
and off for music.

Version 2.0 Software
6
•
Adds several new “MX” presets that exploit the
new audio processing features.
•
By exploiting the 8300’s new signal processing
features, Version 2.0 lets the 8300 import
OPTIMOD-FM 8400 User Presets more accurately.

Navigation is by dedicated buttons,
soft buttons (whose function is context-sensitive),
and a large rotary knob.
The LEDs show all metering functions of the
processing structure (Two-Band or Five-Band)
in use.

OPTIMOD-FM 8300
Achieves extremely tight peak control at all its
outputs — analog left/right, AES/EBU left/right,
and composite baseband.
By integrating the stereo encoder with the audio
processing, the 8300 eliminates the overshoot
problems that waste valuable modulation in
traditional external encoders.

OPTIMOD-FM 8300
Flexible Configuration
9
•
Includes analog and AES/EBU digital inputs and
outputs. Both digital input and digital output are
equipped with sample-rate converters and can
operate at 32, 44.1, 48, 88.2 and 96 kHz sample
rates.
•
The pre-emphasis status and output levels are
separately adjustable for the analog and digital
outputs.
OPTIMOD-FM 8300
Flexible Configuration
•
10
Internal, DSP-based stereo encoder (with a
patented “half-cosine interpolation” composite
limiter operating at 512 kHz sample-rate) to
generate the pilot tone stereo baseband signal
and control its peak level.
OPTIMOD-FM 8300
11
•
Two independent composite baseband
outputs with digitally programmable output
levels.
•
Two sub-carrier inputs that are mixed with
the output of OPTIMOD-FM’s stereo encoder
before application to the composite output
connectors.
OPTIMOD-FM 8300
12
•
Precisely controls the audio bandwidth to 15 kHz.
This prevents overshoots in uncompressed
digital links operating at a 32 kHz sample-rate
and prevents interference to the pilot tone
and RDS (or RBDS) sub-carrier.
•
Defeatable multiplex power limiter that controls
the multiplex power to ITU-R BS412 standards.
OPTIMOD-FM 8300
13
•
Adaptability through Multiple Audio
Processing Structures
•
8300 features three processing structures:
•
Optimum Five-Band for a consistent,
“processed” sound, free from undesirable
side effects (15 or 20 ms delay, depending
on bass clipper mode),
OPTIMOD-FM 8300
14
•
Low-Latency Five-Band for environments
where talent monitors live off-air and they
object to the delay of Optimum
Five-Band (5 ms delay),
•
and Two-Band for a transparent sound that
preserves the frequency balance of the
original program material (17 or 22 ms delay;
crossover-dependent).
OPTIMOD-FM 8300
Controllable
15
•
8300 can be remote-controlled by 5 - 12V pulses
applied to eight programmable, optically isolated
“General-Purpose Interface” (GPI) ports.
•
8300 PC Remote software is a graphical
application that runs under Windows 2000 and
XP. It communicates with a given 8300 via
TCP/IP over modem, direct serial and Ethernet
connections.
•
8300's software can be upgraded remotely
through its serial port or Ethernet port, or locally
(by connecting a Windows® computer to its serial
port through the supplied null modem cable) and
running Orban-supplied downloadable upgrade
software.
