I/O: API 500-series module occupying 2 slots; requires 500-series rack/PSU
Notes: FLAG selectable-transformer feature (Nickel/Iron/Steel) plus unique Transformer Desaturate mode. Derived from the optical stage of the Mastering Compressor. A separate 2-channel rack-format "Dual Optograph" (stereo/dual-mono, non-500-series) exists on the used market; could not confirm it is still in current production (only used listings found), so it is excluded here - treat as possibly discontinued. Price basis: retrogearshop.com stated new retail ~$1,700; UK dealer price ~£1,800 inc. VAT (~$2,250-2,400 equivalent, not used since non-USD).
