He started his career as a radio engineer in a company where his father also worked, and he was later brought to Ortofon by Arnold Poulsen, one of the founders of Ortofon. Initially, Robert Gudmandsen worked on producing a dynamic amplifier for a local radio station. Later he was engaged in the development and production of condenser microphones. In the forties Mr. Gudmandsen had been deeply involved in the basic Ortofon Mono MC system. 10 years later Robert Gudmandsen, one of Ortofon’s then leading engineers, took a principal part in developing of the SPU cartridge.
In 1992 Ortofon wanted to celebrate Mr. Gudmandsen, because of his 50 years of work for the Ortofon. At that time he had already got the nickname Mr. SPU in Japan, because of his basic and innovative work on the mono moving coil and later stereo cartridges. Mr. Gudmandsen was also awarded by the Danish Queen Margrethe II, and Ortofon decided in his honor to launch the SPU Meister cartridge with Mr. Gudmandsen's signature printed in both A and G-models.
