USB Microphone

1、USB microphone model iSV1611 & iSV1610 is a kind of digital microphone with a USB interface, composed of a measurement microphone, preamplifier, 16-bit A/D, and USB interface which can be used with the Apps on smartphone, tablet, or program on PC.

2、Smartphones or tablets or computers will get the digital signal data through a USB cable connecting with iSV1611/1610, combining the program installed on a smart device, just a unit of a digital sound level meter or real-time signal analyzer can do the integral measurement, statistical measurement, Octave, 1/3 Octave, and FFT analysis.

3、Because the digital signal is from a USB microphone instead of the built-in microphone on a smart device, its application meets the standard IEC 61672 Class 1 and IEC 61260 Class 1.
