Notes: IGS cites lineage from 1960s optical limiters, specifically LA-2A and LA-4. Channel count not stated - left blank (likely mono module). Max GR 20dB, max gain 30dB, THD+N 0.012%. A separate, more direct LA-2A-style module already exists as ONE LA 500 - Photon 500 appears to be a distinct/lower-cost opto design (flagged, not a duplicate).
