Optimod XPN-AM Audio Processor
Unprecedented Combination of Loudness, Cleanliness, Crispness, Speech Intelligibility and Coverage
The new OPTIMOD XPN-AM Audio Processor is based upon an AM-optimized version of Orban’s MX limiter technology that was first introduced in the Optimod-FM 8600. This revolutionary limiter technology provides an unprecedented combination of loudness, cleanliness, crispness, speech intelligibility, and coverage. Additionally, XPN-AM’s design incorporates everything Orban has learned in 42 years of AM processing experience, starting with the original Optimod-AM 9000 back in 1977.
Compared to other AM processors, the ability of Orban’s XPN-AM processor to generate greater density with lower distortion can significantly reduce power consumption with Modulation Dependent Carrier Level (MDCL) equipped transmitters. Early field tests show upwards of a 20% power savings is achievable. Depending on MDCL transmitter settings, broadcasters can maximize coverage, minimize power consumption while keeping existing coverage, or split the difference.
There are two different version of the XPN-AM Audio Processor available:
XPN-AM: Analog and AES stereo I/O, low-latency streaming output; built-in Nielsen encoder for AM output; WIBU protection key
XPN-AM/HD: Analog and AES stereo I/O for MPS output, AES stereo for HD Radio output, low-latency streaming output; built-in Nielsen encoder for MPS and HD Radio outputs; WIBU protection key
