The company was originally founded in 1987 as Prism Sound Ltd, the brainchild of two engineers, Graham Boswell and Ian Dennis. They had first met when working on the ground-breaking DSP program at world-renowned audio mixing desk manufacturer Rupert Neve & Company in Cambridge, England. In its early years, Prism Sound became an acclaimed Research & Development consultancy, specialising in digital audio applications. Over the next four years Prism Sound grew rapidly and, by 1991, had grown from two engineers to a team of twelve. The Prism Sound had also grown from an initial business start up to a respected brand, known for performance, quality and reliability. One of the first major projects that Prism Sound undertook at this time was the development of a large commentary and communications switching matrix commissioned by the BBC for the 1992 Barcelona Olympics. This product subsequently became an important market leader in broadcast talkback audio switching. 1992 saw the arrival of Prism Media Products Ltd, a company set up to develop, market and sell Prism Sound branded professional audio products. The aim was to apply the bespoke engineering capability of the company to develop a catalogue of high-end audio products. The catalogue began with studio grade analogue-to-digital and digital-to-analogue converters, which immediately received global acclaim for their audio transparency. Prism Media Products soon recognised, with encouragement from major broadcast organizations, that their uncompromising quality standards would naturally lead to the development of audio test and measurement instruments. The resulting DSA-1 digital audio transmission analyzer has since become a worldwide industry standard in broadcasting and recording studios. There followed the dScope Series III comprehensive audio measurement system exploiting not only Prism Sound's instrument-standard conversion and DSP hardware and software, but also the processing resources of the associated PC. Further expansion of the Test and Measurement product range has continued with the release of a range of dS-NET peripherals and the AutoTestSQL automated test and data logging application. The accurate measurement of today's digital amplifiers is a particular strength of the dScope Series III system. The company's consultancy background enables Prism Media Products to offer an unrivalled responsiveness to customer needs and a cost-effective bespoke engineering service, providing hardware and software solutions to customer-specific audio test requirements. The Prism Sound Group's creative application of its digital audio processing capability also led to the development of the TRANSERV multi-channel voice recording and transcription system. This has diverse applications from call centres, conference facilities and law courts to military, security, broadcast and government legislative assemblies. TRANSERV systems are now in service with many international facilities, Government departments and Defence operations.
