4/19/ :04 AM
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. 2

3. OPTIMOD-FM 8300 User-Friendly Interface

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. 3

4. OPTIMOD-FM 8300 Version 2.0 Software
4/19/ :04 AM
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. 4

5. OPTIMOD-FM 8300 Version 2.0 Software
4/19/ :04 AM
OPTIMOD-FM 8300
Version 2.0 Software
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. 5

6. OPTIMOD-FM 8300 Version 2.0 Software
4/19/ :04 AM
OPTIMOD-FM 8300
Version 2.0 Software
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. 6

7. 4/19/ :04 AM
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. 7

8. 4/19/ :04 AM
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. 8

9. OPTIMOD-FM 8300 Flexible Configuration
4/19/ :04 AM
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

10. OPTIMOD-FM 8300 Flexible Configuration
4/19/ :04 AM
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

11. 4/19/ :04 AM
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

12. 4/19/ :04 AM
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

13. 4/19/ :04 AM
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

14. 4/19/ :04 AM
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

15. OPTIMOD-FM 8300 Controllable
4/19/ :04 AM
OPTIMOD-FM 8300
Controllable
8300 can be remote-controlled by V 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. 15
