OPTIMOD-FM 5300
OPTIMOD-FM 5300 is Orban's new,
affordably-priced processor with many of
the sound processing previously available
only features that were to
OPTIMOD-FM 8400 and 8300 owners.
2
OPTIMOD-FM 5300
The 8400 has developed a reputation as
the FM processor that provides the best
consistency and cleanest speech.
The 5300 reflects this sonic legacy.

OPTIMOD-FM 5300
User-Friendly Interface
An LCD and full-time LED meters make setup,
adjustment and programming of OPTIMOD-FM 5300
easy — you can always see the metering while
you’re adjusting the processor.
4
OPTIMOD-FM 5300
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 5300
Absolute Control of Peak Modulation
6
•
Provides universal transmitter protection and
audio processing for FM broadcast.
•
Provides pre-emphasis limiting for the two
standard pre-emphasis curves of 50 s and 75 s.
OPTIMOD-FM 5300
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 5300 eliminates the overshoot
problems that waste valuable modulation in
traditional external encoders.

OPTIMOD-FM 5300
Flexible Configuration
8
•
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 5300
Flexible Configuration
•
9
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 5300
10
•
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.
SCA1 has internal sensitivity trim; sensitivity trim
available for SCA2 by special order.
OPTIMOD-FM 5300
11
•
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 5300
•
Adaptability through Multiple Audio Processing
Structures
5300 features three processing structures:
•
12
Optimum Five-Band (or “Multiband”;
15 ms delay) for a consistent, “processed” sound,
free from undesirable side effects,
OPTIMOD-FM 5300
13
•
Low-Latency Five-Band (5 ms delay) for
environments where talent monitors live off-air and
they object to the delay of Optimum Five-Band,
•
and Two-Band for a transparent sound that
preserves the frequency balance of the original
program material.
OPTIMOD-FM 5300
Controllable
14
•
5300 can be remote-controlled by 5-12 V
pulses applied to eight programmable,
optically isolated “General-Purpose
Interface” (GPI) ports.
•
5300 PC Remote software is a scalable
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.
•
5300'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.

Exceptional versatility allows you to adjust
the processor’s audio texture to brand your
sound, knowing that the resulting signature
sound will remain consistent, cut-to-cut and
source-to-source.

Branding builds businesses,
and no other processors have
the consistency to brand your sound
like an Orban OPTIMOD.
