Infrasound Microphone - USB - WS2F Industrial Standard

Class 1 - WS2F - DIN IEC 61094-4

Infrasound Microphone

iSV1611-Infra

The first class 1 WS2F-compliant infrasonic measurement microphone with USB interface on the market.
 
It is equipped with a pre-polarized 1/2” microphone capsule that has been specially developed for low-frequency applications and works in a linear range from 1 Hz to 20 kHz.
 
The iSV1611 USB microphone preamplifier is able to perform measurements in two different level ranges simultaneously.
 
The measurement of infrasound is possible with very low ambient noise from a level of 15 dBA.
 
The USB microphone preamplifier is designed for three different sampling rates: 48 kHz, 96 kHz and 192 kHz.
 
This allows the iSV1611 digital preamplifier to be combined with other microphone capsules, e.g. for ultrasound or high-level measurements.
