Pearl Microphone Laboratory AB, Sweden
Sweden's legendary Rune Rosander established Pearl in 1941 which was the first microphone manufacturing company in Sweden, and remained the sole Swedish microphone manufacturer for the next 40 years,
In the beginning, Pearl produced mostly crystal microphone. In the early 1950's, Pearl manufactured large volumes of dynamic microphones for PA-systems. As well as developing the first condenser microphone. Bernt Malmqvist was hired in 1954, and in a few years was promoted to the position of Production Manager of the Pearl microphone range. Simultaneously Malmqvist was involved in R&D at Pearl. Mr. Rosander became Mr. Malmqvist 's mentor for learning every aspect of developing microphones. In 1987, Mr. Malmqvist and his family became the proud owners of Pearl.
At the end of the 50's, the well-known Pearl rectangular condenser capsule was developed. Pearl has continued to improve the capsule over the subsequent 40 years, and today it is one of the very finest capsules available for music recording. From 1960 to 1980, Pearl produced several different kinds of microphones such as crystal, magneto-differential, ceramics, dynamic and condensers for customers such as Ericsson, Tandberg, Radionette, Luxor, Swedish Radio, etc.
In the early 80's, Pearl focused on R&D of microphones only. In close cooperation with Pearl, a separate, trusted company was responsible for manufacture and worldwide sales of the microphones. When this association dissolved, Pearl resumed responsibility for its sales along with production and marketing. The first model in this new "era" was the unique stereo microphone - the TL 4. Since then, Pearl has developed twenty new models appropriate for numerous applications among them a range of stereo microphones.
Pearl rectangular dual membrane condenser capsule
This capsule, a "trademark of Pearl", is used in our studio microphones TL 4,TL 44, DS 60, CC 30,CC 22. The capsule achieves a very flat and resonance free frequency response which extends far into the low - as well as the high frequencies. The framework is made from POM and the electrodes are made from brass. The outside plates (gold plated) which hold the membranes are also made from brass. The membranes themselves are aluminium vapourized. The capacitance of each side is 90 pF at 80 volts polarization voltage.
