Common name: Microtech Gefell MK 231
Production Status: In production
The MK 231 is a 1/2″ microphone capsule with a random incidence response and is therefore optimised for correct measurements in diffuse and reverberant sound fields or in acoustic couplers. The equalisation of the static air pressure is achieved via a tube between the inside and outside of the capsule connected to the preamplifier (rear-vented). The microphone capsule is suitable for sound level meters of Type 1 acc. IEC 61672. Includes wooden box.
