Trident Studios was originally started in 1967 by Norman and Barry Sheffield as the in house studio for the Centredisc label. Following the first major hit to come out of the studio, “My Name is Jack” by Manfred Mann, Trident Studios would establish itself as one of the few top studios in the world.In 1970, the in-house Trident engineers built a small 6×2 desk for the tape copy room which would be the start of much bigger enterprises.Space was a problem in the control room at Trident, with the console location being next to a lift housing. They needed a 16 track desk that would fit in a space of 1.5m but also be able to be upgraded to accommodate 24-track in the near future. After lengthy discussions with various manufactures Trident decided to build the console themselves. A room was set aside on the top floor of the studios and after a year of experimentation, design and building, the first desk was finished and installed. The Trident A-Range was born, followed by B-range, Fleximix, TSM, Series 80, Trimix, Series 80B, Series 70 and others.Source: Trident Audio Developments
