Microphone History:
The EL6020 is a rugged omnidirectional dynamic microphone in a cast metal housing. It was introduced around 1954. The output impedance could be selected by changing the alignment of a 4 pin plug at the rear of the microphone, a feature that was found on several other Philips microphones of the era.*
In 1958 Philips announced that it would be replaced by the EL6041 (Tape Recording Magazine, September 1958, page 20.):
"Philips Electrical Ltd. have recently replaced the EL6020 with a moving-coil, omni-directional microphone designated Type EL6021. Designed for high quality reproduction of speech and music, it is of rugged construction and has a frequency response of 50-10.000 cps.Impedances are 50, 500 and 10,000 ohms and the sensitivity is 1.6mV/microbar ( -56dB) at 10,000 ohms."
However, in 1959, the EL6020 was used alongside other Philips microphones for a large public address installation in Melbourne, Australia. From Radio and Electrical Review, May, 1959, page 22:
"Philips Electrical Industries Pty Ltd. supplied and installed the public address system in the Sidney Myer Music Bowl, Melbourne, which was officially opened on February 12. The system incorporates several unique features to meet all possible requirements.The Myer Music Bowl, of which Melbourne is justly proud, has seating accommodation, for 2,000 in the covered section and space for 20,000people standing or ‘sitting on the surrounding lawns in the King’sDomain.
Six Philips microphones were supplied, consisting of two EL6050 (condenser type), two EL6040 (“pencil” mikes), and two EL6020 omni-directional electro-dynamic units."
* These four pin plugs are now very hard to find.
