Bruel & Kjaer 4006 Condensor Microphone w/ Mic Clip & Windscreen Nose Cone (AS IS) C1122-157-4

Description

Type 4006 are omnidirectional (pressure) microphones which use a 16mm diameter prepolarized condenser cartridge. The diaphragm is a nickel foil which has been coated with an ultra-thin polymer layer for optimum corrosion resistance. The microphone housing is of German silver, an alloy with a high content of nickel to match the stable thermal qualities of the diaphragm. The cartridge has low self noise (typical 15dB(A) re. 20µPa) and high sensitivity (4006: 10mV/Pa). For optimum stability the microphone cartridges have undergone a special pre-aging process which releases all tensions in the materials and stabilizes the polarization voltage.
