Helios Professional Audio Limited

Pro-audio equipment in the Helios tradition

The home of Helios

Richard Swettenham

Helios Professional Audio was set up by Dick Swettenham for the creation of new Helios products while continuing to produce the older models which had made his reputation.

Dick made his mark as an audio engineer in the 1960s when he was working at Olympic Studios in London where he created the world's first transistorised console.

The Olympic desks became well regarded and in 1969 Dick founded the original Helios Electronics Limited company that built equipment for a number of well-known organisations and musicians — see Dick's story.

Dick passed away in 2000 after a short illness.

Helios archive

www.helios-electronics.org shows a collection of documents that Dick left. It will grow over time as the cataloguing work continues and hopefully become a useful reference.


Our intention is to develop new ideas in parallel with offering the iconic sound of the vintage designs. Some of these are listed on the products page.

The order in which products are brought to market will depend on what you, the users, have to say so please get in touch.
