Details
Controls: PC-style software GUI (external monitor/keyboard shown in product photography)
I/O: Analog and AES3 stereo I/O with low-latency streaming output; XPN-AM/HD variant adds AES3 stereo HD Radio output with streaming. Runs on a rack-mount server appliance controlled via external monitor/software GUI (per product imagery)
Notable use: Result of 5+ years of psychoacoustic-model research by Bob Orban to maximize AM/MW/SW reach and intelligibility; incorporates 42+ years of Orban AM processing lineage dating to the original OPTIMOD-AM 9000 (1977); can create dense positive peaks to 125% modulation
Notes: FLAG: classified as Install Processor (closest fit). Ships as a rack-mount server appliance rather than a traditional single-purpose 1RU chassis like Trio/5750/5950 — exact rack-unit count is not explicitly stated in available text (product photography shows a compact rack server), so rack_units left blank rather than guessed. AM-focused (with HD Radio support), not FM. Price and year introduced not published — left blank.
