MI19SW-PC
¼" Microphone

The 1/4” electret measurement microphone 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 measurement microphone is via a BNC socket and is supplied with an adapter cable BNC to 3.5 mm jack plug.

The measurement microphone can be calibrated via a microphone calibrator using a 1/4″ adapter.
