Inovonic 222 AM Audio Processor - 9kHz / 6.4kHz / 5kHz was originally developed as a "post-processor" to ensure US broadcasters' compliance with FCC-mandated occupied-bandwidth regulations. It incorporates a fast, asymmetrical peak limiter, independent pre-emphasis-protection limiting, and a very sharp-cutoff low-pass filter with proprietary overshoot control.
The Inovonic 222 AM Audio Processor - 9kHz / 6.4kHz / 5kHz finds ready application in a wide variety of AM broadcast situations. In addition to the NRSC 10kHz cutoff for medium-wave AM broadcasting in the US, any high-frequency protection characteristic between 4.5kHz and 15kHz can readily be accommodated to meet other domestic and overseas needs. Though the 222 is intended to provide basic final limiting, a "floating platform" release characteristic yields sufficient program dynamics compression that often the unit can be run "barefoot" between the console and transmitter with good results.
- "Audio mask" compliance processing that meets US and overseas AM transmission specifications
- Pre-emphasis, peak limiting and low-pass filtering
- Available in several versions to satisfy NRSC and CCIR medium-wave and all short-wave cutoff characteristics
