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 Set

The MP30 condenser microphone set consisting of a ½” microphone capsule with preamplifier can be connected to all measuring devices with IEPE sensor supply.

The low background noise of less than 18 dB(A) and the linear frequency response from 10 Hz to 20 kHz is ideal for almost any precision measurement.

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).
