Filtronique 1969 – 1974

By 1969 he was operating a cutting-edge audio store, Filtronique. A business based on Lajeunesse Street in Montreal. This is where it all started.

“My story begins in 1973, when a well-known Montreal radio station (CFGL which is then operated by Jean-Pierre Coallier) came to my high-end audiophile store to ask for advice on recording a TV show. live music. I not only supplied the equipment, but then recorded over 50 shows for Canadian radio and television. My three long-standing obsessions – music, audio electronics, and cars – inevitably led me to design my first mobile studio named Filtroson“.

Le Mobile 1977 – 1990

In 1977, Le Mobile was designed and built. “It was the only truck of its kind in Canada, and it combined my passion for customizing cars with a new talent found for on-site recording. At that time, I was using a truck with a gasoline engine, knowing that I would eventually switch it to a diesel. In this new design of the truck you can find a pair of Studer A800s and a Neve 8058 console with Necam faders ”.
“In 1980, I updated The Mobile by replacing the Chevy truck with a new GMC General diesel, the same truck that is still under The Mobile today. I moved to New York which became my base of operations”.
