Trident Studios began production of their Trident A-range recording consoles after failed attempts to get a custom mixing console built for their London studio. Their line of consoles was formally named TRIAD, which stood for Trident Audio Developments, though the consoles were known colloquially as ‘Trident’. One of their major selling points was their ability to interface with a 24-track tape machine, the first console to do so. The Trident’s design was also highly functional and attractive to music producers with new features such as track light indicators. The Trident A-range has been used to record countless classic albums for artists such as David Bowie, Elton John, and Queen. The Trident A-range in National Music Centre’s Control Room A is the fifth of only 13 ever made.
