Over 50 years of Trident History!

Trident Studios was originally constructed 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 mark the start of a much larger enterprise.

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 upgradable to accommodate 24-tracks in the near future. After lengthy discussions with various manufacturers, 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.

That sound was created through painstaking listening tests by the engineers at Trident; people like Ken Scott, Roy Thomas Baker, Malcolm Toft, Barry Sheffield and designer Barry Porter would get together and literally change components until they got the sound they wanted. The sound was crafted more by ear than anything, which ultimately makes its sound stand apart from all others.

The Trident B Range.

Before the installation of the first A-Range, word had already spread. Trident was asked to build a custom version for musician and producer John Congas in early 1972, which would become the Trident B-Range. When a second order came in from Chipping Norton Studios, Trident Audio Developments, or TRIAD, was officially formed as a manufacturing company.

With the newly formed Trident Audio Developments initial success of both the A-Range and B-Range consoles, development began on new console designs to expand the company’s offerings. Trident quickly experienced even more success with the Fleximix and TSM consoles both being released in 1979.

The Trident Series 80

In 1980, the first Series 80 Console was released and quickly became Trident’s most successful console. The Series 80 was followed by the Trimix, and then the revered Series 80B console was released in 1983. The 80Bs became one of the most popular consoles at the time, offering many options and configurations at a price point that made Trident console the most competitive option of the time.

The Series 80B established itself as a world-renowned console, not only because of its features, but particularly because of its EQ. The 80B EQ is considered one of the best EQs, especially for rock. The list of artists and albums cut on 80Bs is so extensive, a complete list is difficult to compile. As a testament to the consoles, the 80Bs still remain in demand and are working to this day!
