About Nagra
Audio Technology Switzerland S.A. develops, produces and sells the Nagra brand, headquartered in Romanel-sur-Lausanne in the Lake Geneva region. The products cover three areas: high-end HiFi equipment for home sound reproduction, professional audio recorders for film, TV and radio production, and devices for security and law enforcement applications. The tradition dates back to 1951, when Stefan Kudelski developed the Nagra I, the first portable audio recorder. Originally part of the Kudelski Group, Nagra is today run by the independent company Audio Technology Switzerland. Its sales representation spans more than 30 countries worldwide, with dealers including in Belgium, Brazil and South Africa.
