D240x Ultrasound Detector
D240x Ultrasound DetectorD240x Ultrasound Detector
Very popular heterodyne and time expansion detector with backlit, large digit, accurate digital display, showing the tuned frequency in the heterodyne mode. The frequency and volume controls are on the side of the case, making it easy to adjust. Using stereo headphones, the heterodyne signal is heard on the left channel and the time expansion signal on the right channel. When the built-in speaker is used, a switch is used to select the heterodyne or time expansion signal.
A digital recorder can be connected to the D240X to record the time expanded calls for analysis on a PC. If the recorder has a “voice activated” recording mode, a fully automatic bat recording system is obtained, which can be left in the field for unattended recording of bat calls.

D500X Ultrasound Detector/Recorder Mk I
D500X Ultrasound Detector/Recorder Mk ID500X Ultrasound Detector/Recorder Mk I
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.
| Weight | 1200 g |
| Dimensions | 165 × 170 × 53 mm |
| Class | Direct, high-speed recording |
| Microphone | Advanced electret, jack for external microphone |
| Frequency range | 15 kHz – 190 kHz (500 kHz sampling rate, high-pass filter enabled) 5 kHz – 190 kHz (500 kHz sampling rate, high-pass filter disabled) |
| Connections | External microphone, external trigger, external DC supply |
| Timer | Four on/off periods per day |
| Bandwidth | 8 kHz (+/- 4 kHz), -6 dB |
| Batteries | 4 x AA size, Alkaline or NiMH recommended |
| External DC supply | 5.5-8 V, typically ca. 200 mA (average, when recording), depends on CF card type and number of CF cards |
| Recording | ADC Resolution: 16 bits Anti-aliasing filter: Yes, 8th order, 190 kHz cut-off frequency Sampling rates: 44.1, 300, 500 kHz (optimized for 500 kHz) Recording length: 0.3, 0.5, 1, 2, 3, 5, 10, 20 sec or manual recording Recording medium: CF card, 4 slots |
D500X Ultrasound Detector/Recorder Mk II
D500X Ultrasound Detector/Recorder Mk IID500X Ultrasound Detector/Recorder Mk II
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.
