Orban Optimod 9100A AM Processor

The 9100 is a complete audio processing system for AM. It provides automatic gain control to ride levels, high-frequency boost to compensate for the roll-off in receivers (for a brighter sound), and a six-band limiter with distortion-canceling clipper for a very loud and clean sound. OPTIMOD-AM dramatically improves AM station fidelity and perceived loudness, easily overpowering competitors using other processors.

•Very high average modulation (loudness) with exceptional fidelity and freedom from artifacts.
•Near-FM quality from typical auto, portable and table radios.
•Compensates for high frequency rolloff typical of all AM receivers.
•Stereo versions approved by Motorola for C-QUAM. Mono version can be easily field upgraded to stereo.
•Distortion-canceling, six-band limiter dramatically increases RMS modulation without pumping.
•Two outputs with independent controls for use with two transmitters.
•Compensation circuits for correcting anomalies (tilt, overshoot, ringing) in transmitter/antenna systems.
•Analogue meters indicate broadband AGC and gain reduction of six-band limiter.
