Designed to allow calibration of ½" and 1" condenser microphones by the insert voltage technique, either in conjunction with the reciprocity method or with a known sound source. The insert calibration facility is used for reciprocity and insert voltage calibration of condenser microphones in accordance with IEC 1094 – 1: 1992 and ANSI S1.10.

  • Insert voltage calibration of condenser microphones for open-circuit voltage determination
  • Calibration of condenser microphones with respect to reciprocity calibration methods
  • General sound measurements in connection with Brüel & Kjær condenser microphones
