MK 231 E 1/2“ Microphone Capsule for random incidence sound ﬁeld • WS2D acc. IEC 61094-4 • random incidence • 3,5 Hz to 16 kHz • 15 dBA to 149 dB • prepolarized The 1/2“ microphone capsule MK 231 E has a random incidence response and is therefore optimized for correct measurements in diffuse and reverberant sound ﬁelds or in acoustic couplers. The equalization of the static air pressure is by means of a capillary to the preampliﬁer (rearvented). The microphone capsule is suitable for sound level meters of Type 1 acc. IEC 61672. Delivery Microphone capsule, nickel in wooden case 90 mm x 90 mm x 40 mm Options and Accessories Electrostatic actuator instead of standard protection grid Adapter for 1/2“microphone capsules to 1/4“preampliﬁers Angle adapter 1/2“ Dehumidiﬁer adapter 1/2“ Wind
