Pye also marketed its own line of consumer electronics used for decoding quadraphonic records. These products were not especially successful. The last LP release in this series was in 1977. As PRT Records When the rights to the name Pye (then owned by Philips) expired in 1980, the label changed its name to PRT, which stood for Precision Records and Tapes, via a brief flirtation with Precision. At that time, it had sub-labels such as Fanfare Records, a late 1980s and early 1990s UK-based Hi-NRG label issuing records by Sinitta, R&B Records, a 1980s disco/electro label featuring Imagination, and Splash Records, which featured Jigsaw and the Richard Hewson Orchestra/RAH Band.
