Outdoor USB Microphone
iSV1611-R
USB Weatherproof Microphone
The USB microphone model iSV1611 is a digital microphone with USB interface, consisting of pre-polarized ½” electret microphone capsule, preamplifier, 2 channel (Stereo) ADC and USB interface, which can be used with apps on smartphone, tablet or PC.
PC, smartphone, or tablet receive the digitized 2 channel signal data via USB cable connected to iSV1611. The dual channel operation allows simultaneous measuring in the 16 -100 dB(A) and 56 – 140 dB(A) range.

Weatherproof Microphone
MR40
Outdoor microphones are used for outdoor acoustic measurements or monitoring of tissue and traffic noise.
ROGA outdoor microphones are equipped with a windscreen, a rain cover and a bird deflector to protect them from such and other weather influences.
The MR40 outdoor microphone can be calibrated with a sound calibrator eg CA111 by carefully removing the windscreen and rainscreen.
The sound entrance at a 90º angle to the microphone axis is ideal for monitoring ambient and traffic noise.
MR40 is a 1/2-inch pre-polarized condenser outdoor microphone.
It is suitable for continuous use in rainy days or in a very high or very low temperature environment.
MR40 uses a WS2F and IEC 61672 Class 1 MP40 microphone, which is characterized by its stability.
It is the best choice for long-term outdoor use, such as noise monitoring.

MR40 Microphone Rain Cover
In principle, all 1/2″ microphones can be converted with these parts.
11.7mm-60 UNS protective grid thread is a prerequisite for converting a microphone into a weatherproof microphone
