Details
Controls: Input pad (mic/line), gain (42-60dB)
I/O: Mic/line input with flexible input pad, XLR I/O via PS6 rack tray (Neutrik XLR connectors, military-grade Cinch Jones module-to-tray connectors)
Notes: Two-stage EF86/6267 pentode tube circuit, homage to 1950s-60s European designs (Telefunken/Langevin/Collins/Gates style). $1,899 is per-module price only; PS6 Rack Tray and PS6 Power Supply required to operate it are not separately priced on the site — flagged, not guessed. Channel count of 1 is inferred (not explicitly stated) the same way as the CA-70 (CA-286S is described as a single-channel standalone version of this module). Product page did not surface tone-control/filter detail or phantom power info despite a targeted fetch — left blank rather than guessed. No frequency response, dimensions/weight, year of introduction, or notable-use credits published on the site.
