High-quality full spectrum recordings at a price never seen before!


The M500 microphone is easily used with a tablet PC or laptop to record bat calls and other ultrasonic signals with the highest quality.         


The M500 USB Ultrasound Microphone comes in a small and durable aluminium enclosure. It utilizes the same advanced electret microphone technology as the well-known D500X detector and can be used both in directional and omnidirectional modes (with or without the directional horn).


Low-noise technology, high sampling frequency and efficient anti-aliasing filter provide highest quality recordings.


The microphone comes with a free 'Lite' version of the easy-to-use BatSound Touch recording program that saves the recordings as 16 bit wav files. Real-time display of the waveform and the spectrogram as well as real-time monitoring of the bat calls are also available. The program offers various triggering modes; manual and automatic, with or without pretrigger, level triggered or frequency triggered operation.


A 0.5 m USB (type-A to mini-B) cable is included. A type mini-B to micro-B/OTG USB cable, suitable for use with a smartphone or tablet, can be purchased separately.
