Notes: FLAG device_class: unit is simultaneously a full 8ch mic-pre interface AND a converter/DSP mixing console with onboard 128x64 mixer and 100+ zero-latency hardware plug-ins; classified as Audio Interface per task guidance. 4th-generation ('mkIV') successor to the 'ULN-8 3d' referenced in the research brief -- 'ULN-8 3d' is no longer a currently-sold model (current site lists only mkIV generation as of research date); LIO-8 mkIV page's own comparison table confirms 3d -> mkIV as predecessor/successor. price_usd = MH Direct store list price (mhdirect, item 000-50046, productid=10008), verified 2026-07. year_intro left blank: page does not state it; third-party sources (Gearspace forum thread, Production-Expert 'Product of 2022') suggest mkIV series first shown ~2021-2022, not confirmed on official MH pages so omitted per no-guess rule. Bundled MH Production Bundle v4 software (~$3100 value) excluded from scope (software, not hardware).
