Thread for Microphone Capsule Mounting | 11.7 mm-60 UNS |
The iSV1611 digital USB microphone preamplifier is suitable for all common pre-polarized 1/2” microphone capsules.
The thread type 60 UNS allows the combination of different microphone capsule manufacturers depending on the application.
WS2F – IEC 61094-4
The 1/2” infrasound microphone capsule is designed for acoustic measurements in research, development and industry and is also used in building acoustics and audiology, among other things.
- Frequency range 1 Hz to 20 kHz
- Free Field
- Measuring range 15 dB(A) to 135 dB
The microphone capsule has a fixed charge carrier layer (backelectret) to provide the polarization voltage.
The careful construction and the constructive concept of the microphone capsules guarantee a high temporal constancy of the electro-acoustic parameters.
The internationally common thread type (60 UNS) for connecting the microphone capsule allows interchangeability with other 1/2” microphone capsules and enables connection to all suitable calibration and measuring devices.
