The aka c414 This microphone has been released and re-released over the years because it is such a great workhorse. It has four switchable polar patterns (cardiod, hypercardiod, figure of eight, and omni), a 0-10-20db selectable pad, and a 0-75-150Hz low end rolloff filter.
Now we are getting in to the last few days Yesterday was the U47 / U48. Today its the brauner vma
The U 47 was the first microphone with a switchable pick-up pattern. By manipulating the polarization voltage on the rear diaphragm the mic can achieve either a âcardiodâ or an âomniâ pattern. A nearly identical microphone was also made, the U 48, whose only difference was a different method of Read more…
The workhorse. The legendary SM58 is an industry-standard, highly versatile cardioid dynamic vocal microphone, tailored to deliver warm and clear vocal reproduction. The SM58 is consistently the first choice for vocal performances around the globe.
The laser microphone. The Laser microphone system is operated by transmitting an invisible beam to the window of the target room. The window pane is slightly vibrating in accordance to the sound waves emanating from speech.
Astatic 600 âConneautâ microphone This streamlined, rocket age 1946 design was named after the town where Astatic was headquartered (Conneaut Ohio). It was made in 2 versions, one with a chrome grille (pictured) and another with an elaborate molded plastic grille in the shape of a jet engine air intake.
RCA 6226 Aeropessure Type microphone The âAeropressureâ was a rugged radio announcing and public address microphone designed for on-location use, featuring exceptional wind noise suppression. During its some five decades of microphone production, probably no other single manufacturer came close to the technical engineering expertise, development innovation, and product line Read more…
RCA-77 This microphone was commercialized in late 1933 as the RCA 77A Unidirectional Microphone. The microphone was an instant success. The RCA 77A was followed by the RCA 77B, 77C, 77D and finally the 77DX. The 77A was a huge mike which had a rounded top and a flat bottom. Read more…
Probably the most recognisable mic… Shure Model 55A Unidyne âFatboyâ.
RCA Ribbon Microphone In the early 1920s, Drs. Walter H. Schottky and Erwin Gerlach co-invented the first ribbon microphone. A few years later, Dr. Harry F. Olson of RCA started developing ribbon microphones using ï¬eld coils and permanent magnets. The RCA Photophone Type PB-31 was commercially manufactured in 1931 greatly Read more…
The First Condenser Mic. In 1916 the brilliant electrical engineer Edward Christopher “E.C.” Wente invented the condenser microphone.
Blake Transmitter In 1877 Francis Blake invented a carbon microphone for use in the telephone, shortly after Thomas Edison invented a microphone that also used carbon contacts. Blake used a carbon button design that initially would not stay in adjustment, but with later improvements proved to be workable. Alexander Bell Read more…
Bell’s Double Pole Membrane Transmitter. Bellâs Double Pole Membrane Transmitter and Iron Box Receiver were used in 1876 to transmit and receive the worldâs first one-way long distance telephone call from Brantford to Paris, Ontario. Canadaâs first two-way long distance telephone conversation was between Montreal and Quebec in 1877.
This year I am going to make an advent calendar using my blog. It will be featuring cool or historically important microphones. This is Bell’s original liquid transmitter from a set of Bell Laboratories photographs in the Ron Christianson Telephone Collection.
