Neumann History Quality Must Be Measurable To meet the operating conditions encountered in the studio the microphones are subject to testing throughout their manufacture. The cap- sules alone undergo more than 50 different tests before final assembly. Since the very beginning in 1928 Neumann condenser microphones have always operated on an audio frequency circuit, with the capsule consequently acting as a very high-impedance generator, rendering it highly sensitive to mois- ture. And as moisture
