Outdoor Microphone Type 4952 (Type 3639-E)
Fig. 2
Outdoor Microphone
Type 4952 with
integrated coupling,
fitted on the top of a
water pipe
The outdoor microphone is a major factor in ensuring that the NMT complies with
IEC 61672 Class 1 requirements, with either 0 or 90
°
reference direction.
It functions correctly under conditions of up to 96% relative humidity, and in ambient
temperatures ranging from –30 to +55
°
C. The precision condenser microphone is
protected inside the acoustically optimised windscreen, which has an anti-bird spike
fitted at the top. Construction is elegantly simple, ensuring longevity and low
maintenance costs.
The microphone can be mounted on standard 1
″
water pipe, allowing stable
mounting and secure cabling. A range of tripods and microphone mounting systems
(for example, 4 m masts and hydraulic masts) are available from, or can be
recommended by, Brüel & Kjær.
During transport, the microphone can be safely placed inside the NMT cabinet. For more information, see
