PLACID PMNP4229 High sound pressure microphone set
PMNP4229 High Sound Pressure Microphone is ¼ inch prepolarized pressure field microphone that uses IEPE Power Supply and does not require polarization voltage. The Preamplifier housing is made of stainless-steel material and is suitable for pressure field environment such as in cavities, near hard reflective surfaces, or installed flush with hard surfaces. The microphone adopts side pressure equalization method, which increases the maximum sound pressure level of the microphone by increasing the membrane tension.
