Formula Sound is a British manufacturer of analogue audio mixing equipment, founded in Stockport by Tony and Sandra Cockell. The company designs and builds its products in the UK, with a manufacturing facility in Oldham and offices in the London area, and has focused throughout its history on analogue circuit design rather than digital signal processing.

The company's catalogue spans professional DJ and zone mixers, broadcast and installation desks, foldback systems, and a line of system-protection hardware including automatic volume controllers, cut-off limiters, and fire-alarm priority interfaces used in clubs, bars, and other licensed venues. Formula Sound's best-known DJ products include the FF-4000 and FF-6000 rotary-style fixed-format mixers, both developed in collaboration with Funktion-One, alongside models such as the AT-1 and the Sentry MK2 noise limiter.

The brand has a particular reputation in the UK club and installation market, where its mixers and noise-management units are common in fixed sound systems. Its analogue-only philosophy and hand-assembled, made-in-Britain approach have given it a niche following among engineers and DJs who favour rotary mixers and traditional signal paths.

Formula Sound has 2 products cataloged on Equipboard, including Mixers and DJ Mixers. Their gear is featured by 4 artists, with the strongest followings in Rock and Electronic. Notable users include Mr. Scruff, Ryan Miller, and Adam Gardner.
