About us

Helios Electronics Limited

From about 1996 Dick Swettenham developed the idea of resurrecting his Helios operation with a view to manufacturing digitally-controlled analogue equipment for the professional audio market, so Helios Professional Audio Limited was born. This company holds the Helios trademark and licenses its use to Helios Electronics Limited and Audio Digital Technology.
