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 our history.


Our intention is to offer the iconic sound of the vintage designs and develop new ideas. The plan is to start by re-issuing the Type 69 Passive Equaliser, the Type 78 5-band Parametric Equaliser and the Type 760 Compressor/Expander.

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


Our plans to launch in 2018 fell through but we hope to announce a new production schedule at NAMM (24-27 January 2019).
