3,600 kr excl VAT

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

The M500 microphone is easily used with a Windows PC/tablet/laptop to record bat calls and other ultrasonic signals with the highest quality. For recording with the M500, the BatSound Touch or BatSound Touch Lite software is used.

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.

Please note that the tablet and cable are only shown as reference. The tablet is not included with the M500 and the supplied cable is a USB Mini-B/USB-A type.
