In 2004, for a taste of the challenge, Laurent Nobs founded RTV-Sat in Gland.


Laurent Isabella joins him; the two partners develop their business around satellite and TV installations. The evolution of technology is gradually moving the core business to high-end audiovisual and home automation.

RTV-Sat is called TV Frequency.

Initially Frequence TV was particularly devoted to a private clientele in the cantons of Geneva and Vaud. Today, thanks to the growing power of its audiovisual and home automation integration skills, we serve a diverse clientele of individuals, businesses and public administrations throughout Romandie (and beyond).


The year 2015 marks a turning point with the merger between Frequence TV and Lerch Audiovisuel, the key player of the Côte.


In 2016 the head office moved from Gland to Nyon.


A new Bang & Olufsen space is inaugurated in Nyon in 2017.


Partnerships with several brands of high quality products (Bang & Olufsen, LG, Crestron, Lutron …) are reinforced and a second B & O space is opened in Geneva.

Our philosophy

Qualitative solutions made easy

Our client is at the center of our attention and our goal is to always carry out a project that follows a clear execution and whose result is adapted to the need.

Our support of the project, from the design to the training to the installed products, through its installation, is essential so that the final result meets the most demanding requirements of our customers.

To meet this high level of expectations, the exchange and advice with customers and their representatives is essential. They make it possible to identify the specific requests and to provide the customized solution that corresponds to their needs.

So over the years we develop a relationship of trust with the customers we support.

We welcome you with pleasure in our two spaces in Nyon and Geneva for a first exchange to identify your needs.

Quality products

Through the partnerships established with top-of-the-line positioning brands, such as Bang & Olufsen, Bowers & Wilkins, LG, Creston and Lutron, we seek above all to offer qualitative solutions that are easy to use and will evolve in the future.

We regularly follow the latest developments in the audiovisual and home automation fields to offer solutions always at the cutting edge of innovation.

A human-sized team

The service at the heart of our concerns

The progressive growth of our activity allowed us to constitute a small team united around common values.

We were 5 people in 2009, 10 in 2016 and more than 20 at the end of 2019.

A family spirit

We are committed to the friendly atmosphere within our team.


Each member of our team is responsible for a portfolio of clients. This organization allows us to ensure a personalized monitoring of facilities: you do not work with an anonymous technician but with a partner you know, whose skills match your technical needs.

We are convinced that this autonomy offers the best service to our customers.


Thanks to the moderate size of our team, we are able to arrange our schedules quickly and be responsive to your requests.


Although historically located on the coast, we have the ability to follow our customers according to their needs, everywhere in Switzerland and abroad.

A valuable team today … who is preparing for tomorrow.

In a very specific field of activity and in perpetual evolution, we rely on the training of apprentices to renew our workforce and maintain our skills at the level expected by our customers.
