Frequently Asked Questions

Can I use an SMM-U1 or SMX-U1 microphone to record non-ultrasonic signals?

Our newer ultrasonic microphones (SMM-U1 and SMX-U1) have built-in high-pass filters at 8 kHz to cut down on wind noise and other sources of low-frequency rumble. This means that any sound at frequencies lower than 8 kHz will be significantly reduced in volume or completely absent.
