MI19SW-PC
¼" Microphone
The 1/4” MI19SW-PC is a microphone that can be connected directly to analog audio inputs of computers or mobile devices.
It is equipped with IP55 splash protection and the WS-RG-40 wind protection as standard, so that it is also suitable for permanent surveillance outdoors in a shelter.
The electret capsule is protected by a water-repellent stainless steel grid and can also be replaced later because the stainless steel microphone housing can be opened non-destructively.
The class 1 frequency response according to IEC 61672 and 22 mV/Pa high sensitivity have proven themselves for years.
The electrical connection of the microphone is via a BNC socket and is supplied with an adapter cable BNC to 3.5 mm jack plug.
The microphone can be calibrated via a microphone calibrator using a 1/4″ adapter.

Measurement Microphone with high sensitivity 320 mV/Pa
and low self-noise level below 6.5 dBA
The MMS 214 has a particularly low inherent noise level and is designed for acoustic measurements of low sound pressure levels close to the threshold of human hearing. The electrical connection is via a BNC cable to devices with IEPE supply. The microphone preamplifier internally generates the polarization voltage for the externally polarized microphone capsule. The measurement microphone is equipped with a build-in memory for microphone identification (TEDS acc. IEEE 1451).
