DETAILS

ITEM MODEL: Bruel&Kjaer Audio Microphone Type 4992 and B&K 2669 Preamplifier. 

CONDITION: This device was last used by a major electronics manufacturer. It is fully tested and in working condition. 

DESCRIPTION: The B&K Type 4192 ½-inch Pressure field Microphone is esigned for high-precision coupler measurements or ANSI noise measurements. Pressure-field microphones are optimised to have a flat frequency response in a pressure field. The microphones should be used for making measurements in small, closed couplers or close to hard, reflective surfaces. Type 4192 is suited for situations where a robust and stable pressure-field microphone is required.

The B&K Type 2669 Preamplifier is designed to operate over a wide range of temperature, humidity and other environmental conditions. The preamplifier has a very high input impedance presenting virtually no load to the microphone. The high output voltage together with an extremely low inherent noise level gives a wide dynamic range.
