In the late 1950’s Electro-Voice ceased production of both ribbon and condenser microphones. In an article in his series ‘MICROPHONE FACTS for the operating engineer’ Electro-Voice founder Lou Burroughs explained the decision and presented reasons why dynamic microphones were, in every way, superior. The feeling at Electro-Voice was that ribbons and condensers were too fragile and prone to failure and that dynamics were solid and reliable and sounded better. Towards the end of the article (referring to dynamics) Burroughs declares that ‘These are the microphones of the future’.
Today, although dynamic mics are still revered for their robustness and ability to handle high SPLs they are not generally considered to be sonically superior to all other microphones! Indeed, I can’t imagine many engineers taking a pair of dynamics out to record an orchestral concert of classical music instead of their usual selection of condensers and ribbons.
Compared to condensers Burroughs claimed that dynamics have a ‘smoother high frequency response’ and so, here (by way of an experiment) is a clip from an orchestral concert I recorded recently using a pair of Soviet Era, Russian, Oktava MD186 dynamics! I was simply curious to see if Lou Burroughs maybe had a point?
