Today the name of Sennheiser brings together a number of strong brands: Georg Neumann in Berlin, the world’s leading producer of studio microphones, is among them, as well as Sennheiser Streaming Technologies in Germany where we develop innovative Streaming solutions. We operate the world’s most modern headphone production line. As a result of our first-class service and market research we have developed a unique understanding for the needs of our customers, who include DJs, travellers and computer gamers as well as the elderly and those people who are hard of hearing. The way to this achievement has been paved by our trailblazing ideas. Ever since electrical engineer Prof. Dr. Fritz Sennheiser founded the company in 1945, Sennheiser has been continuously setting trends in the audio industry. Right up to the present, our innovative inspiration, curiosity and passion have made our products and services immensely successful. Wherever people care passionately about recording, transmitting or playing sound, Sennheiser will be there. This is something we are proud of. This is how strong the signal is exiting out of the receiver into the sound board/speakers/etc. Typically this will be set to 0 dB or +6 dB if connected to equipment which is expecting a line level input . If you are connected to equipment expecting a mic level input you will typically need to drop this AF output down to -24 dB or -30 dB. If your equipment has the option, it is best to try to run the equipment in line level mode.

With this end in mind, we have restructured our organisation. Two independent business units , the Consumer Division and the Professional Division, enable us to focus on the different requirements of our customers and the market. On this path, Sennheiser has set many technological milestones - the first directional microphone in the fifties, the open headphone in the sixties, infrared transmission technology in the seventies and multichannel cordless transmission in the eighties. In the nineties we developed head-related surround systems, while intelligent audio information systems were the focus of our interest at the start of the new millennium - and today we continue to drive the progressive digitalisation of the audio world and create immersive audio experiences with the 3D audio technology program AMBEO. NOTE: If the AF Output is too high it may over load the input on any connected equipment (sound board/speakers/etc) and may create noise in the form of distortion/rumbling. Our Professional Division bases its activities on the discovery of cordless technology, to which Sennheiser has been actively contributing since 1957, when it launched the early Mikroport brand, the name of which is still used as a synonym for cordless audio channels today. This was followed by the first infrared music transmission in 1975 and the most successful microphone series to date, the ‘evolution wireless’. We invest above-average sums in research and development. The creativity of our designers knows no limits. An example is the development of our professional digital radio microphone system. This took us 15 years of research, in the course of which we repeatedly had the courage to reject ideas completely and start again from scratch until the sound quality finally reached perfection. Our Integrated Systems Division offers microphones, conference systems, products for the hard of hearing, PA systems and guided tour technology. We are the suppliers who offer complex audio systems in the form of a simple product. Among our customers are companies of all sizes, government institutions and non-profit organisations, schools and universities, religious establishments, the hotel and catering trade and many audio and video rental companies. We are proud of the fact that we are an independent family business. This is an important factor for our success. Our financial independence guarantees our freedom to act and our competitiveness, and so ensures the future of our company.So what was once ‘The W Laboratory’ in a half-timbered house in Wedemark near Hanover has grown to become a global company.
