B&K Type 5008 Microphone Calibrator

POLARIZATION VOLTAGE CALIBRATION UNIT

Type 5008 is a differential DC buffer intended to act as a buffer for high-impedance microphone polarization voltage, allowing the microphone polarization voltage to be measured using a common DC voltmeter.

Description

Type 5008 is a high-impedance differential DC buffer intended to act as a buffer for high-impedance microphone polarization voltage, allowing the microphone polarization voltage to be measured using a common DC voltmeter.

For measuring 0V or 200V Polarization Voltage:

  • At the input of a measuring instrument
  • At the input of a microphone amplifier
The polarization voltage can either be measured in a 7-pin preamplifier socket or direct at the input terminal of a preamplifier.
