Focusrite ISA 115-H
Little is documented about the Focusrite ISA 115-H. This model number does not appear in any of the available period research. That research covers the ISA 116, ISA 220, ISA 428, and ISA 828 from the Focusrite ISA series. It is unclear whether the 115-H is a variant of another model, a different channel strip or module, a designation that never reached production, or a model known under another name in the surviving record.
What can be said with confidence comes from period context about Focusrite itself. By the late 1980s, the company was building a strong reputation in professional audio. Mix-Magazine (August 1987, p.23) published endorsements from prominent engineers. Kevin Mills of Larrabee Sound described the gear as “quiet, transparent, and very musical,” and Robert A. Tis of Electric Lady Studios called it “one of the jewels of the industry.” A later directory listing in Mix-Magazine (October 1987, p.261) shows Focusrite U.S. Ltd. with an office in Wheaton, Illinois. It also lists specifications for what appears to be an unidentified Focusrite product - 50-ohm input impedance, recessed front panel gain control from −70 dB to +14 dB, separate power supply, and short-circuit-proof outputs, priced at $820. No model name is attached to those figures in the surviving OCR text, and there is no evidence linking them to the 115-H.
Beyond these fragments, nothing more is recorded about this model. The Archive has a page for the 115-H, so it once existed as a distinct item. What it was remains undocumented in available sources.
