Orban will demonstrate XPN-AM, a new way to manage audio processing for AM stations, at NAB booth N2024. XPN-AM is the result of more than five years of research by processing pioneer Bob Orban. It exploits a psychoacoustic model to maximize the reach and intelligibility of AM transmissions while lowering distortion and reducing listening fatigue.
“Over the years, AM listeners have had to contend with increased RF noise from everyday devices such as computers or CFL/LED lighting,” said David Day, Orban president. “A good solution on the part of AM broadcasters is to adjust audio processing for more apparent loudness. However, traditional audio processors usually experience an increase in distortion when they do this, and it keeps stations from realizing their desired ‘signature’ on the AM dial. XPN-AM fixes this. It’s both loud and incredibly clean.”
At NAB, Bob Orban will conduct a demonstration of XPN-AM versus other current AM processors, utilizing a Nautel J1000 AM transmitter to most accurately show real-world conditions. As Orban switches between the processors, attendees will be able to hear the differences in both loudness and distortion.
"In 2010, Orban first introduced its disruptive MX limiter technology in Optimod-FM 8600,” said Bob Orban. ”The MX limiter uses a psychoacoustic model to significantly lower distortion, increase transient punch, and improve high frequency power handling capability. For the first time, Orban's XPN-AM now brings this same revolutionary limiter technology to AM radio, providing an unprecedented combination of loudness, cleanliness, crispness, speech intelligibility, and coverage. Additionally, XPN-AM’s design is informed by everything we have learned in our 41 years of AM processing experience, starting with the original Optimod-AM 9000 in 1977."
“AM is most definitely NOT dead,” said Day. “Some of the top billing radio stations in the USA are AM operations. With XPN-AM, AM stations across the country can now claim their rightful place as leaders on the dial.”
