Pettersson D240x
Heterodyne and Full Spectrum Time Expansion Bat Detector

Pettersson D240x
The bat detectors from Pettersson Elektronik are high quality instruments, designed in close cooperation with leading bat workers for optimum performance in full spectrum recordings.

Features

Frequency range:10 - 120 kHz

Two detectors in one! Select between HET or TE technology at the flip of a switch. A backlit, digital display shows tuned HET frequency. This is used when actively monitoring bat activity so you can hear in real time when the detector is receiving a strong bat call.

Listen to the HET output in real-time for the ideal bat pass while the D240x simultaneously records the full spectrum (10-120 kHz) sound. When a suitable, desired bat has just passed by and the HET clicks are starting to fade, single-handedly stop the full spectrum recording with a button push on the back of the D240x. The D240x will continually replay the full spectrum (and now time expanded) call which can be off-loaded to a separate recording device such as the H2 Zoom or into a laptop running SonoBat or Batsound.

Flip the master output switch to TIMEEXP to listen to your newly recorded bat pass in 10x time expansion and the high quality tonal qualities that only full spectrum recordings can capture.

Small size: 119x60x25mm with built in loudspeaker.

Manual and level-sensitive automatic triggering.

Frequency-selective trigger in the level-sensitive mode allows user to exclude certain frequency ranges.

Record various lengths of TE calls to an on-board memory chip: 0.1s, 1.7s (recommended for passive monitoring), and 3.4s (recommended for active monitoring).

Attach a digital recorder for a compact, reliable passive recording package or to enable voice notes during active monitoring, without a computer.

Capable of automatically capturing bat calls and, using a separate control box, off-load TE calls to a connected recorder.

The TE signal stored in the detector memory can be replayed at its original rate through the HET system.

Power: (1) 9-V alkaline battery; operates for 12-16 hours

Output: (1) audio line out, (1) headphone port

The front of the D240x shows the center of the tuned frequency band when in heterodyne mode. This readout has no bearing when recording in TE which is always full spectrum. It records TE constantly even when listening to the HET output, enabling you to wait for a good bat pass before triggering a TE save so you avoid lesser quality calls.
Switches are arranged on the rear so that the all important start/stop recording button is naturally under your finger when holding the detector during active monitoring.

The D240x features an autotriggering setting with an adjustable threshold to send more calls and less noise to your recorder when used passively.

The D240x TE output can be saved without a laptop using a digital recorder such as the Zoom H2 recorder. Using the SonoBat AutoParser utility these calls are time stamped and waiting for further analysis.
