ROGA NVH Microphones

The ¼” condenser microphones MI15, MI17, MI19, RG-50 and MI21 are free-field types with integrated electronics. All types can be supplied with close tolerances (±0.5dB) with transfer factors between 25 and 100mV/Pa. Power is supplied by a constant current source IEPE (standard) with usually 4mA. Coaxial cables are used as feed lines. As a standard the microphones are equipped with BNC connectors and are also available with TNC connector.

The microphones should not be exposed to aggressive environmental conditions.

1/2" USB Measurement Microphone
Class 1 WSF2

The USB microphone model iSV1611 is a digital microphone with USB interface, consisting of pre-polarized ½” electret measurement 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 measurement in the 16 -100 dB(A) and 56 – 140 dB(A) measurement range.

  • Frequency range                                                                                                        3.5 Hz – 4 kHz: ± 0.5 dB                                                                                            4 kHz – 20 kHz: ± 1.5 dB
