Cadac Electronics  Cadac Holdings Limited (limited Company, company Number 06704124) are a manufacturer of sound mixing desks for live music productions, theatres, recording and broadcast. Cadac desks presently are most famous for large scale musicals such as ""Phantom of the Opera"" (from 1984 till 2008), ""The Lion King"", ""Mamma Mia!"" and ""We Will Rock You"" but historically from the late 1960s to the mid-1980s were installed in famous recording studios around the world including Lansdowne Studios, Manor Studios, Wessex Studios, Scorpio Studios and George Harrison's Friar Park Studio. Clive Green retired in 2001. In early 2009 the assets and IP of the company were purchased by Mr. Xianggui Wang of the Soundking group, China. In 1967 Clive Green started working with Adrian Kerridge at London's Lansdowne studios, working on replacing all the valve parts for an old EMI desk with solid state technology and modifying the desk for 8 track recording. In 1968 Terry Brown (a sound engineer at Lansdowne and Olympic) was asked by Barry Morgan and Monty Bason to set up the new Morgan studios. He asked to buy the designs for the new desk Clive and Adrian had been working on. Clive suggested that he build the desk for Terry, and got together with Adrian, David Bott an engineer from "TVT", and Charles Billet of Audix (who made the frames for the desks). The brand name Cadac came from the combination of their names (Clive, Adrian, David And Charles). The first desk was delivered to Morgan, who continued to use their services. These were 8 track split console designs with no automation and transformer balanced inputs and outputs. Many desks are still in operation in studios all over the world. The last studio desk to be installed is still at Air Edel Studios in London. In 1984 a sound engineer, Martin Levan, from Morgan Studios was asked to put on a live show, "Little Shop of Horrors", and the first desk was built for live theatre. Cadac launched a digital audio network called MegaCOMMS, that was designed to work with many many complex applications. It embedded control data in a data stream to avoid losing audio channels. It could carry up to 128 channels of 24-bit, 96 kHz audio, in addition to control data, using two RG6 coaxial cables. It also allowed for phase-aligned clock distribution via embedding markers in the data stream, which in turn allows synchronisation of multiple hardware elements within the network.
