The 1970's saw the emergence in the USA, the UK and subsequently worldwide of the discotheque as a prime entertainment venue for a new, young generation, and of the creation of a new and major role for the DJ. Cloud Electronics was created during this period by founding partners Roy Millington and Andrew Colley, specifically to provide this dynamic and growing industry with its own purpose-designed, professional audio tools. Over the course of more than 30 years the demand for Cloud's particular brand of "clearly better sound" continues to grow.

The Cloud VTX range of four-channel power amplifiers are intended for commercial and industrial public address and sound reinforcement applications where unquestionable long-term reliability is the primary consideration. There are three models in the range: The amplifiers are designed to deliver their full rated power into loads down to 4 ohms for long periods of time. The circuit design includes clip limiting and switch-on delay, together with DC, thermal, short-circuit and reactive load protections. All models are built in a very solid steel 2U chassis, and employ variable–speed forced-air cooling.
