R&D Report 1954-41 : The AKG electrostatic microphone Type C12. H.D. Harwood, R.J Packer A new electrostatic microphone, type C 12, has been produced by the firm of Akustische und Kino-Gerate Gesellschaft in Vienna. The nominal polar characteristic of the microphone can be varied from omnidirectional through cardioid to a figure-of-eight by a multi-position remote control switch. Frequency response, sensitivity and noise have been measured on a single specimen for these three conditions....

R&D Report 1954-23 : The Neumann microphone Type U47 H.D. Harwood, R.J. Packer A new directional electrostatic microphone, type U 47, produced by the firm of Neumann in Berlin, incorporates the capsule originally designed for the type M 49 microphone but uses a cheaper form of head amplifier. The U 47 microphone is designed to give either cardioid or omnidirectional polar response. Frequency characteristics, sensitivity and noise have been measured on a single specimen for both conditions....
