Orban’s OPTIMOD-FM 2200 DIGITAL Audio Processor is a complete audio processing system for FM broadcast. Model 2200 is configured for analog inputs and outputs. Model 2200-D also includes digital inputs and outputs. Features for all versions include: • Universal Transmitter protection and audio processing for FM broadcast. The 2200 can be configured to interface ideally with any commonly-found transmission system in the world. • User-friendly Interface: A simple liquid-crystal display (LCD) makes setup, adjustment and programming easy. Front panel bargraphs show metering functions of the processing preset in use. Push one of the clearly labeled soft keys to RECALL a preset, to MODIFY PROCESSING, or to access SYSTEM SETUP controls. • 8 factory-programmed presets, based on Orban’s Two-Band and Protection/Limiting Processing Structures. These presets can be modified and saved. • 8 user presets to store customized settings. • Pre-emphasis limiting for the internationally-used pre-emphasis curves of 50 μs and 75μs. The pre-emphasis control is almost never audibly apparent, producing a clean, open sound with subjective brightness matching the original program. • Extremely tight peak control; overshoot is limited to ± 0.3dB! • DSP-based stereo encoder (stereo generator) produces a circuit with excellent specs, high stability, and uncompromising baseband spectrum control. • Remote-control, via optically-isolated terminals that can be operated with contact closures (to facilitate interfacing to older-technology remote controls). • Built-in line-up tone generator facilitating quick and accurate level setting in any system and a Bessel Null tone for calibrating modulation.
