Cadac, established in England in 1968, design and build digital and analogue audio mixing consoles for concert touring, theatre, installation, broadcast and recording applications.


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 Studios) was asked by Barry Morgan and Monty Bason to set up the new Morgan Studios. Morgan Studios wanted to buy the designs for the new desk Clive and Adrian had built for Lansdowne. Clive suggested that it would be a better idea if he built the desk for Terry. Clive together with Adrian, David Bott, an engineer from "TVT", and Charles Billet of Audix (who made the frames for the desks) formed a separate company - Cadac. The name was derived from the first letter of each of their christian names; Clive, Adrian, David And Charles – hence Cadac. This was also the beginning of a long relationship between Cadac and Morgan Studios.

The new desk was an 8 track split console design with transformer balanced inputs and outputs but no automation. Many desks are still in operation in studios all over the world with the last ever studio desk being installed, and still working, 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 this resulted in the first Cadac desk built for live theatre. The spec dictated that is should be of “studio quality audio” and that the front-to-back dimension couldn’t be deeper than a row of seats. This allowed for one row to be taken out by the console and another by the engineer.

This was the start of Cadac dominating the theatre market with nearly 70% of theatre shows using Cadac desks. Performances included: Billy Elliot, We Will Rock You, Hairspray, Jersey Boys, Lion King, and Wicked and on Broadway: 13, Avenue Q, Chicago, Guys and Dolls, Gypsy, Hairspray, Jersey Boys, Lion King, Mary Poppins, Pal Joey, South Pacific and Wicked. The longest continually serving Cadac console in London was on Phantom of the Opera where it was used from 1984 until it was finally replaced in 2008.

Not all Cadac consoles were found in recording studios and theatres, they were also the console of choice for concert touring for many internationally acclaimed performers including; Rolling Stones, Van Halen, Franz Ferdinand, Pavarotti, Andrea Bocelli, Status Quo, The Beach Boys, Tom Jones and Bryan Adams

Today, Cadac have a range of both analogue and innovative digital consoles aimed at the live sound market and the company is continually investing heavily in research and engineering to develop the next generation of digital consoles.

Cadac's flagship is the CDC eight digital audio system.

CDC eight features 192 fully processed audio paths, pre-configured as 128 input channels and 64 busses, coupled with an intuitive user interface with “high agility” gesture navigation on 24” full-colour touch screens. Audio is transported to and from remote stageboxes by Cadac’s propriety 128 bi-directional 96 kHz / 24-bit MegaCOMMS protocol, with industry-leading low latency. With the addition of a MegaCOMMS Router the network can be expanded to 3072 channels.

What makes the CDC eight different?

In addition to Cadac’s unique approach to the user interface, employing gesture-based operation any smartphone user will understand, the CDC eight provides superb audio quality due to Cadac’s legendary mic pre combined with a time-aligned, phase-coherent mix bus architecture resulting in sub 0.4 millisecond latency.

Cadac’s innovative approach to the user interface means it is far less menu dependent than traditional digital consoles. As a result engineers will have a minimal learning curve as they will be navigating the console without the need for intensive training by using gestures which will be familiar to any smartphone/tablet user. The CDC eight’s uncoloured, transparent audio quality is a perfect match for any application.
