The story of PSI Audio started in 1975 when Alain Roux started producing his first speakers while studying at EPFL in Lausanne.

Two years later Alain started making a profit selling his speakers and decided to found a company called Roux Electroacoustique. In 1988 the company became a Limited Company and was renamed Relec SA. At this time Alain also relocated the company in to a new purpose built facility in Yverdon-les-Bains.

Over the years, Alain and his team developed a huge variety of speakers starting from the Hi-Fi industry, Public Address systems all the way to Professional Studio applications. Many speakers where also produced as OEM products under the brand names of respected international companies. Several of these products have gone on to win the industry’s most desirable awards.

In 1991 an analogue and digital electronics section was added to the acoustic laboratory and electronics expert Christian Martin was recruited, to lead development in these areas.

From 1992 until 2003, Relec SA had the privilege to work in close partnership with Studer. Relec SA developed and produced the OEM line of monitors for Studer comprised of A1, A3 and A5 all of which are recognised worldwide.

In 2004, Studer was acquired by an international group and had to stop selling studio monitors under the Studer brand. Relec SA and Studer therefore had to discontinue their fruitful relationship.

This was then the start of PSI Audio brand in the studio monitoring…

Since then, PSI Audio has developed to become a respected worldwide brand, producing the ultimate professional studio monitors.

In 2016, PSI Audio released the first active bass trap, named AVAA C20. Entirely analogue, it allows you to push the laws of physics by fighting room modes. From then on, the AVAA technology was launched and development has never stopped.

It was not until 2023 that the first fully digital AVAA was introduced: the AVAA C214.

PSI Audio now offers a full range of highly innovative studio monitors with cutting edge fully analog technology and 2 different active bass traps.
