The FR125-EXT system is a
recording system developed for extended duration
monitoring projects. The system includes the FR125-EXT recording
unit along with a 20 foot EXT microphone cable and the choice of a
directional or hemispherical ultrasonic microphone element.
The system can support cable lengths of up
to 250 feet. Longer cables are available at additional cost.
Drawing just 3.2 Watts, the FR125-EXT is one
Acoustic Technologies lowest power recording solutions. It is capable of
recording up to two weeks using a small 40 Ah external car battery and
it will operate continuously with the addition of a 20 Watt or larger
includes an integrated backup battery, an embedded microcontroller, a
high speed 16-bit digitizing system and two USB connectors which allow
it to control and operate an ultrasonic microphone along with a
combination of external USB hard-drives, Compact Flash writers, or USB
Internally, the FR125-EXT runs an embedded version of
SPECTíR software. It supports an operation timer, the WAVPACK loss-less
compressed file format, sleep mode to conserve battery power, a file
scrubber to reduce noise-only files, and a
remote file transfer mode that will automatic transfer recordings back
to a specified FTP site.
The FR125-EXT is backwards compatible and will operate
with either Binary Acoustic
Technologies EXT ultrasonic microphone units or with our USB-based
