Details
Controls: Same stepped Ratio/Attack/Release/makeup-gain control set as standard Obsidian, VU meter
I/O: XLR balanced main in/out, XLR external side-chain input; transformerless signal path (field-upgradeable to transformer/TXIO version)
Notable use: Marketed for mastering, classical/jazz, and other sources wanting the cleanest signal path without transformer coloration.
Notes: OFFICIAL SITE UNREACHABLE (dramasticaudio.com does not resolve, verified July 2026); info sourced from retrogearshop.com dealer page. This is the same chassis/control set as the standard Obsidian but with the input/output transformer omitted for a cleaner path; per the dealer, this variant was offered partly due to transformer supply-chain shortages, with a factory or self-install (no-solder) upgrade path back to the transformer version. JUDGMENT CALL: treated as a distinct current SKU rather than a mere option, since dealers list/price it separately from the standard Obsidian. Year introduced and precise frequency-response numbers not published — left blank.
