Focusrite ISA ISA One (2008)
The ISA One is a desktop microphone/instrument preamp with an independent D.I., a stereo cue section, and an optional A/D converter. Its one significant period review appeared in Mix (December 2008, p.96). Barry Rudolph noted that it uses the same amplifier section as the acclaimed ISA 110 module and the channel strips of the large Focusrite Forte studio console. The company's own 2008 advertising placed that board at BOP Studios in South Africa and described it as probably the most expensive console ever built, with an installed cost of over $1,000,000 and 72+ channels.
The ISA One isn't a straight copy of that circuit. It revises the range of mic gain settings and adds a variable input impedance control. Dimensions are 11.25 × 9 × 4.5 inches. That's about all the record holds. The ISA One appears in Mix from May through December 2008, in both that ad campaign and the single review, and little else is documented. Original price, full specifications, and production years beyond the 2008 marketing push remain unconfirmed.
