OPTIMOD-FM 8300

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

• 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.

5

OPTIMOD-FM 8300


• 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.

6

OPTIMOD-FM 8300


• 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.

7

OPTIMOD-FM 8300

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.

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.

8

OPTIMOD-FM 8300

Flexible Configuration

• 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.

9

OPTIMOD-FM 8300

Flexible Configuration

• 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.

10

OPTIMOD-FM 8300

• 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.

11

OPTIMOD-FM 8300

• 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.

12

OPTIMOD-FM 8300

• 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),

13

OPTIMOD-FM 8300

• 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).

14

OPTIMOD-FM 8300

Controllable

• 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.
