Pettersson D500X MKII c/w External Microphone
Product code: 12510
The D500X Mk II is as easy to use and provides the same features as the classic D500X, with the following exceptions:
*It does not include an internal microphone. Instead it ships with an external microphone which is either directly connected to the microphone jack or through an extension cable. The microphone jack is an XLR type so no adapter cable is required.
*It is powered by 4 C type batteries which last roughly three times longer than the AA batteries used in the classic D500X.
*The jack for external power is a standard 2.5 mm DC power jack for easy connection.
The D500X is an ultrasound recording unit intended for long-term, unattended recording of bat calls. In contrast to time expansion bat detectors, the D500X records full-spectrum ultrasound in real time with virtually no gaps between recordings. The recorder is equipped with four slots for CF cards, which typically makes it possible to leave the unit in the field for more than a month. The triggering system allows the device to automatically start recording as a sound is detected.
The recording length can be selected in steps from 0.3 up to 20 seconds (or continuous in manual mode). In order not to fill the card too fast at locations with high activity, a minimum time between two recordings can be applied. The recorder is normally operated in a low-power mode with no pre-trigger (i.e. the recording starts as the sound exceeds the chosen threshold level), but both pre-and post-trigger functions are available in the standard (not low-power) mode. The D500X stores the bat calls in time stamped wav files.
The D500X comes in a rugged and weather-protected aluminium housing. A soft protection case with straps to hang the unit in e.g. a tree is included.
Various accessories are available, such as microphone extension cables up to 100 m.
