The front membrane
greatly decreases
the sensitivity
in ultrasonic range
so provide a
shelter from rain and unscrew and remove the front membrane to have a better sensitivity.
Versions
Three VT Ultra-Mic384 versions are available:
-
VT Ultra-Mic384 USB MICROPHONE
-
VT Ultra-Mic384 BOTTOM RECORDER
The different versions have the same circuitry and as a consequence the same functionality.
VT UltraMic-384 USB MICROPHONE
The easiest way to detect and record ultrasound, all integrated in a
delrin
container and aluminum tube.
VT UltraMic-384 BOTTOM RECORDER
The hydrophone version. The bottom recorder is essentially an UltraMic installed into a plastic case specifically designed to
support high pressure for deep sea recordings.
Waterproof
VT Ultramic-384 is a waterproof IP67 microphone when the front cap is tightly screwed. The USB connector is – not a
waterproof device, therefore it must be protected from humidity and dust. The microphone sensor is protected by a PTFE
membrane glued to the black front cap.
Even if the membrane is very thin it will block a part of ultrasonic sounds. If you don’t need the waterproof protection or if you
have provided a custom shelter for VT UltraMic-384 from rain, then unscrew the front cup so you’ll get all the sensitivity of VT
UltraMic-384.
While the VT UltrMic-384 is water resistant and designed to operate in an outdoor environment, it is strongly recommended that
the VT Ultramic-384 be protected from the direct rain or snow. In addition, please note that it will be difficult for the sound to be
captured by the sensor if the windscreen or the sensor becomes wet.
Finally, please ensure that the USB cable leads down from the device so that any water is channeled away from the microphone,
minimizing the chance of water infiltration through the grommet.
