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.
