Adcom GFA-2535 (c.1992–1994)

Name: Adcom GFA-2535
Brand: Adcom

Not much is documented about the Adcom GFA-2535 beyond a handful of magazine ads and short product announcements from the early 1990s. The record shows a multi-channel power amplifier aimed at the new home theater market. It also worked as a flexible power source for multi-room audio systems.

Audio (December 1992, p.15) ran an introductory ad calling the GFA-2535 an "award-winning amplifier" that could deliver 200 watts of clean power. The ad copy was vague on specifics, as ad copy tends to be. A more detailed description appeared in Audio (March 1994, p.4). It noted a rear-panel switch that let the user select either three- or four-channel operation. In three-channel mode, the amplifier was meant for home theater. In four-channel mode, it could act as a centralized power source for distributed audio. The same announcement mentioned that the GFA-2535 had been exhibited at the Consumer Electronics Show, where it was described as "award winning."

No schematic details, measured performance figures, or owner feedback from the period have surfaced in the available record.
