  1. OPTIMOD-FM 8500 OPTIMOD 8500 is Orban's flagship FM processor. It builds on the successful sound of the 8400 version 3 by doubling the sample rate and DSP horsepower while adding new features. Processing for HD Radio, digital radio and netcasts is built-in and offers 20 kHz audio bandwidth. 2

  2. OPTIMOD-FM 8500 An eight-second diversity delay lets you use the 8500's stereo coder and second-generation dual-mode composite limiter (hard clipper or “Half-Cosine Interpolation” limiter)to achieve unprecedented analog FM loudness. Plus, 13 speech-mode controls let you fine-tune the processing independently for music and speech. 3

  3. OPTIMOD-FM 8500 Because the analog and digital channels share most of the processing, they always have the same processing texture, so your signature sound is intact. But the digital channel uses optimized look-ahead peak limiting to create a cleaner, brighter and punchier sound that sells the benefits of HD Radio to the mass audience. 4

  4. OPTIMOD-FM 8500 HD radio's big advantage is that its digital channel isn't crippled by the pre-emphasis that destroys high frequency headroom in FM. When your listeners hear the digital channel, they can hear modern mixes with all elements intact — but only if you've correctly processed your audio specifically for the digital channel. 5

  5. OPTIMOD-FM 8500 With 8500 HD FM peak limiting, the mass audience can hear a dramatic difference in punch and sparkle between the digital and analog channels. Yet both channels still have your signature audio texture, with the same stereo enhancement, AGC, EQ and multiband compression. 6

  6. OPTIMOD-FM 8500 User-Friendly Interface A large (quarter-VGA) active-matrix color liquid crystal display (LCD) makes setup, adjustment and programming of the 8500 easy. Navigation is by a miniature joystick, two dedicated buttons and a large rotary knob. The LCD shows all metering functions of the processing structure in use. 7

  7. OPTIMOD-FM 8500 Use the Locate joystick to navigate through a menu that lets you recall a preset, modify processing (at three levels of expertise) or to access the system's setup controls. 8

  8. Menu OPTIMOD-FM 8500 • Fast & intuitive. • At-a-glance view: • Recall Presets, • Modify Processing. • Save Presets. • Adjust I/O Levels. • System Settings. 9

  9. Presets OPTIMOD-FM 8500 • Selecting any Preset is easy. • Metering stays on screen so you can see processing changes. 10

  10. Basic Modify OPTIMOD-FM 8500 • LESS/MORE control • Affects only, dynamics processing • User-friendly. • Equalization. • Stereo Enhancement. • Fast, Easy, Safe. 11

  11. Intermediate Modify OPTIMOD-FM 8500 • More control over the sound. • Requires more time to adjust and listen. • Requires more experience: • Not as easy, • Not as safe. 12

  12. Advanced Modify OPTIMOD-FM 8500 • Dozens of controls for power users. • All controls are available. • Requires lengthy adjust-listen cycles. • Requires serious audio processing experience: • Intricate and Risky. • Extremely powerful in the right hands. 13

  13. Speech Mode OPTIMOD-FM 8500 • You can set many of the processing parameters separately for speech signals, as detected by the 8500's speech/music detector. • This allows you to tune the processing separately for speech and music 14

  14. Save / Save As OPTIMOD-FM 8500 • User Presets permit you to change a Factory Preset to suit your requirements and then store those changes. • You can store as many User Presets (at least 100) as you have available memory. • Enter here any name you wish, up to 18 characters. 15

  15. Input / Output OPTIMOD-FM 8500 • Global Settings. • Analog I/O. • Digital I/O. • Digital Sync Input. • Composite Output. • ITU412 Setup. • HD Setup. 16
